the population of owls decreases
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.
Decrease, as snakes are predators of frogs and an increase in snake population would lead to more predation on frogs, reducing their population.
Yes, an organism without predators can harm an ecosystem by disrupting the balance of the food chain. Without natural predators to control their population, the organism can overpopulate and outcompete other species for resources, leading to a decrease in biodiversity and potential ecosystem collapse.
As the owl population increases and they consume more mice, the immediate effect is a decline in the mouse population. This reduction in prey can lead to a subsequent decline in the owl population over time due to food scarcity. Additionally, the decrease in mice may allow for the recovery of other species within the ecosystem, potentially leading to a more balanced food web. Overall, these dynamics illustrate the interconnectedness of predator and prey populations in an ecosystem.
One factor that can affect the populations in an ecosystem is that, if an ecosystem had owls with no predators, the owl population would increase and eat all the mice in the ecosystems. The population of the mice would decrease more and more.
When a living thing is removed from a food web the population of it's predators will decrease and the population of its prey will increase, disrupting the ecosystem of the living thing.

If the owl population increases, the vole population will decrease. This is because there will not be enough voles for all of the owls. Then the owl population will decrease, therefore causing another increase in vole population.

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.
