What is the relationship between a cheetah and the environme by Issac Miller on Prezi
Mar 1, Examples of Predator-Prey Relationships. Cheetah and Gazelle. In the African Savannah, the most famous example of predator-prey duo will. Mar 7, Cheetahs are second level consumers. They are carnivores. Cheetahs eat gazelles, gazelles eat grass, and the grass go through. May 1, Cheetahs and Gazelles The wild animals are vast and various in number. They all have some kind of relationship to animals because they all.
If cheetahs could think of what animal to feed upon, they would like to choose the gazelle, but they would also know that the gazelle is a quite formidable foe. Even though the discovery channel may show the gazelle getting caught and killed by the cheetah all the time, it is not even close to being like that.

The gazelle is a common animal, so that is why the cheetah hunts the gazelle, but if the cheetahs had reasoning, they would choose to chase a much easier animal like the hyena. It is instinct to chase the common animal because that is how a certain species can survive.
Their instinct is to hunt the most common animal so that is why the cheetah hunts the gazelle. The cheetah acts strictly based upon instinct when they choose to hunt. So it is easy to say that the cheetah acts upon instinct rather than the belief that they act based upon reasoning. The gazelle uses their instinct rather than reasoning. The gazelle is often the prey of cheetahs.
Yes, both the cheetah and the gazelle live in the same habitat, but they feed on different things. Gazelles eat plants, herbs and seeds while cheetahs eat meat. Why does the gazelle go to the drier parts of the savannah and not stay in the grassy parts where the cheetahs do not go as much?
It is because they have little reasoning, so they use their instinct to base all of their decisions. These drier parts of the savannah are where the cheetahs like to hunt. These areas where the grass shoots sprout are the favorite feeding grounds for the gazelles, so is it instinct that or reasoning that the gazelle chooses to eat in the drier parts of the savannah.
It is instinct because if they realized that the cheetahs live and hunt there, then they would not go to those places and choose to eat in the moderately warm areas where the cheetah does not live.
If the gazelles realized that the cheetah lived in the dry, sunny areas of the savannah, then they would not go to those parts as much as they do now.Leopard 'Befriends' Impala: Unusual Predator - Prey Interaction Caught On Camera
It is this reason that makes it seem hard to believe that the gazelle uses reasoning, or even that the cheetah uses instinct. If the gazelle could realize that the cheetah hunts in the drier areas, then they could possibly have some reasoning, but they do not realize that the cheetah hunts in the drier parts of the savannah, so it is hard to believe that the gazelle could have reasoning because it does not realize that it could eat plants and seeds in the softer ground areas where the cheetah does not go.
The gazelle does not realize that they are at a disadvantage in certain areas, so the gazelle uses instinct rather than reasoning. There are however reasons to believe that the gazelle and cheetah use reasoning. This is because the gazelle is able to make many zigzag-like moves without slowing down, while the cheetah is unable to make these quick changes in direction as well as the gazelle can.
The gazelle realizes that it is slower than the cheetah, but it also knows that the cheetah is unable to make quick, swift moves like the gazelle can. Also, the cheetah can only run full speed for a couple hundred yards at most, so all the gazelle has to do is run in zigzags for a little bit to slow the cheetah, so that they gazelle may get away or even kill the cheetah itself. The gazelle now has a reason for going to the habitat of the cheetah because they may realize that they can beat the cheetah.
If they use this knowledge, then yes the gazelle uses reasoning. This pattern is known as a hierarchy or a food chain. The hierarchy does not go on indefinitely, and ends at what is described as the top of the food chain. For example, in some ocean ecosystems, sharks are at the pinnacle of the food chain. Other than humans, such so-called apex predators are not prey to any other species.
This relationship applies only to the particular ecosystem that the apex predator is in. If transferred to a different ecosystem, an apex predator could become prey. For example, the wolf, which is at the top of the food chain in northern forests and tundra environments, could become the prey of lions and crocodiles if it were present in an African ecosystem.
Predator-prey relationships involve detection of the prey, pursuit and capture of the prey, and feeding. Adaptations such as camouflage can make a prey species better able to avoid detection.
10 Dumbfounding Examples of Predator-Prey Relationships
By blending into the background foliage or landscape and remaining motionless, an insect or animal offers no visual cue to a predator since it mimics its surroundings. There are many examples of mimicry in predator-prey relationships. Some moths have markings on their outer wings that resemble the eyes of an owl or that make the creature look larger in size. Insects popularly known as walking sticks appear similar to the twigs of the plants they inhabit.
Another insect species called the praying mantis appears leaflike. The vertical stripes cause individual zebras in a herd to blend together when viewed for a distance. To a predator like a lion, the huge shape is not recognized as a potential source of food. Camouflage can also be a strategy used by a predator to avoid detection by prey.
An example is the polar bearwhose white color blends in with snow, reducing the likelihood that the bear will be detected as it approaches its prey. In this case, the same strategy and color can be utilized by young seals, since their color allows them to be invisible as they lie on the snowy surface. The community of individuals and the physical components of the environment in a certain area.
A sequence of organisms, each of which uses the next lower member of the sequence as a food source.
An interconnected set of all the food chains in the same ecosystem. The natural location of an organism or a population. Factors that influence the evolution of an organism. An example is the overuse of antibiotics, which provides a selection pressure for the development of antibiotic resistance in bacteria.
The opposite of camouflage can occur. A prey can be vividly colored or have a pattern that is similar to another species that is poisonous or otherwise undesirable to the predator. A successful predator must judge when pursuit of a prey is worth continuing and when to abandon the chase. This is because the pursuit requires energy. A predator that continually pursues prey without a successful kill will soon become exhausted and will be in danger of starvation.
Predatory species such as lions are typically inactive during the hot daytime hours, when prey is often also resting, but become active and hunt at night when conditions are less energy taxing and prey is more available. Similarly, bats emerge at night to engage in their sonar-assisted location of insects that have also emerged into the air. When supplied with food in a setting such as a zoo, predators will adopt a sedentary lifestyle.
Predation is an energy-consuming activity that is typically done only when the creature is hungry or to supply food for offspring. In settings such as an aquarium, predators and prey will even co-exist.
Being a prey does not imply that the creature is completely helpless. The prey may escape from the predator by strategies such as mimicry, or can simply outrun or hide from the predator.
Some species act coordinately to repel a predator. For example, a flock of birds may collectively turn on a predator such as a larger bird or an animal such as a cat or dog to drive off the predator.
This mobbing type of repulsion can be highly orchestrated. As well, some bird species use different calls, which are thought to be a specific signal to other birds in the vicinity to join the attack. Even birds of a different species may respond to such a call.
The fluctuation in the numbers of a predator species and its prey that occurs over time represents a phenomenon that is known as population dynamics. The dynamics can be modeled mathematically. The results show that a sharp increase in the numbers of a prey species an example could be a rabbit is followed soon thereafter by a smaller increase in numbers of the relevant predator in this case the example could be the fox.
As the prey population decreases due to predator killing, the food available for the predators is less, and so their numbers subsequently decline. With the predator pressure reduced, the numbers of the prey can increase once again and the cycle goes on. The result is a cyclical rising and falling of the numbers of the prey population, with a slightly later cyclical pattern of the predator.
A famous predator-prey model is the Lotka-Volterra version. The two equations were formulated in the mids by Italian mathematician Vito Volterra — to explain the decline in a fish population observed in the Adriatic Sea during World War I — At the same time, American mathematician Alfred Lotka — was using the equations to explain the behavior of some chemical reactions.
Their efforts were recognized as the Lotka-Volterra model, which represents one of the first examples of ecological modeling. Other examples include the Kermack-McKendrick model and the Jacob-Monod model used to model predation of one bacterial species on another.
Impacts and Issues Predator-prey relations are an important driving force to improve the fitness of both predator and prey. In terms of evolution, the predator-prey relationship continues to be beneficial in forcing both species to adapt to ensure that they feed without becoming a meal for another predator.

This selection pressure has encouraged the development and retention of characteristics that make the individual species more environmentally hardy, and thus collectively strengthens the community of creatures that is part of various ecosystems. For example, lions that are the fastest will be most successful in catching their prey. Over time, as they survive and reproduce, the number of fast lions in the population will increase.
