What relationship occurs between prey and another organism?

predator kills and eats prey for its survival. When the predator population increases, the prey population decreases because of too many hunters. When the prey population decreases, the predator population decreases because of the lack of food. Then, the prey population increases because there aren't that many predators and the process repeats itself.


Why is it not a good idea to leave poisoned food for top level consumers in an ecosystem?

If the top level consumers, the apex predators, are poisoned and their population decreases dramatically, then their prey animals have no population control. The prey then has a population boom. In turn, the prey animals decimate their food source, harmng the ecosystem as a whole.


Biotic factor that affects the size of a population in a specific ecosystem?

Predation is a biotic factor that can affect the size of a population in a specific ecosystem. The presence of predators can limit the growth of a population by preying on individuals. This can result in a decrease in the population size.


Does the number of squirrels an ecosystem can support depend on how many predators eat them?

No. The number of a species supported by and ecosystem depends on how much food is available in the ecosystem. If the population (squirrels) exceeds the food supply then some of the population will die. Predators are a factor in controlling population size.


In an ecosystem in Africa lions are predators for zebras. The lion population increases and they eat more zebras. This decreases the zebra population. What happens next?

This is a very simplified scenario. However, in this scenario, the decreased zebra population would not provide enough food for all the lions. Some lions would starve or leave to find food somewhere far away. Once the lion population had decreased enough, the zebra population would recover, and the ecosystem would be back in balance. Note, however, the lion population would usually not spontaneously increase unless the population of prey animals increased first, which would only happen if plants grew especially well for a year, or if one of their predators had a population decrease.

Is the population of predators density dependent?

Yes, the population of predators is density dependent, meaning that it is influenced by the availability of prey and competition for resources within their ecosystem.


Why might large predator populations be a good indicator of the ecological heath of an area?

A large population of predators indicates a healthy ecosystem that supports a large population of prey animals.


How does the presence of predators help keep the ecosystem stable?

Well predators keep the population of like deer from eating all the plants


What are some common predators of very small insects in the ecosystem?

Common predators of very small insects in the ecosystem include spiders, ants, beetles, and certain species of birds and frogs. These predators play a crucial role in maintaining the balance of the ecosystem by controlling the population of small insects.
