Predators are very important in the community because if they didn't catch their prey, then their prey would become overpopulated and there would not be enough producers( Grass, plants etc.) for the prey.
predators and prey do depend on each other in that the predators rely on prey for food and they keep population of prey in check which if they did not there would be over population and food for prey would be decreased and they could die from lack of food.
The predator could help the prey be healthier by slightly decreasing the population so that there is more food available for the remaining members of the population.
A change in the prey population effects the predator population because if there are alot of preys, then the predators would eat the preys and the population of predators would increase. But on the other hand, if there are not enough preys, the predators would starve and die which would decrease the population of predators.
Oftentimes, the predator holds the population of a particular prey in check. Without predators, the population of the prey will flourish. If the change of predators you refer to means 'type of predator', the prey will adapt -or vanish.
Because when a predator feeds on prey, the prey population goes down. When the prey population goes down, then so does the predator population. When the prey population recovers, then the predators soon after prey on the prey, and it repeats.
The various trophic levels will regulate a population when organisms feed on other organisms. The different levels are producers, consumers and decomposers which help in maintaining the nutrient cycle.
Prey, because the prey use camoflage to hide themselves from predators. Also, predators could also use it to hide from other predators or hunters (humans).
True, if the number of prey decreases, the predators will have nothing left to eat and will slowly starve. In some cases the predators will become cannibalistic (eat its own species) to prevent it self from starving to death.So the answer is true, if a prey population decreases the population of its prey will decrease as well.
The connection between prey and predator is that predators are organisms that eat other organisms, and prey are the organisms that are eaten. For example, lion's are predators and zebra are an example of their prey. This can also refer to plants: rabbits are the predators and lettuce is the prey. Without prey, the predators would have nothing to eat. Without predators, the preyy population would increase to the point of overpopulation.
This is a much studied relationship that one might learn about in grade 10 science or Biology 11. Predators rely on the population of their prey for sustenance. An increase in predators could lead to a decrease in the population of the prey which in turn leads to a decrease in the predator population. As the predator population decreases the prey population can again increase and the cycle begins anew.
The predators keep prey populations balanced.
A large population of predators indicates a healthy ecosystem that supports a large population of prey animals.
