∙ 9y agoThis 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.

∙ 6y agoIt results in a population cycle where populations riseand fall over a predictable period of time. It's like a computer program.
Start
- Lots of lions
- Adequate zebras
- Lions eat zebras
- Too few zebras
- Some lions starve
- Are there enough lions to form healthy breeding population? (Yes: go to #10, No got to #12)
- Are there enough zebras to form a breeding population? Yes: Go to #,10 No: Go to #12)
- More zebras than the remaining lions need
- Zebra population expands
- Lion population expands
- Go back to #1
- Lions die out
- Zebra over population
- (Go to End)

The death rate of Lions increase
In a certain ecosystem owls are predators for mice. The owl population increases and they eat more mice. This causes the mouse population to decrease. What happens next?
the population of owls decreases

the population of owls decreases. (Apex)
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.
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.
What effect did removing predators have on prey?
By Removing prey the predators don't have enough food to eat so the predator population decreases.
What describes all stable ecosystems?
The population of predators are dependent on the population of preys

Biotic factor that affects the size of a population in a specific ecosystem?
The number and kinds of predators in the 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
