Animals also influence other animals and plants. Herbivores, which are animals that consume plants, usually consume plants that are common to their environment. These animals have developed specific adaptations for consuming these plants, such as claws or sharp teeth to break nuts. Carnivores, which are animals that consume other animals, also have adapted for their environment. Carnivores may have long legs for speed to catch up to prey, or they may be capable of flight. For example, cheetahs can run as fast as 115 km per hr.

The number of predator, prey and plant life also influences each other. As an example, if several plants were to die off in a biome, the number of herbivores would likely decrease. With fewer herbivores to feed on, carnivores might disappear as well. If there are too many carnivores, then the number of herbivores will decrease as well. If there are less herbivores, the number of plants increase. You can see why all of these factors come together in complex ways.
