Explanation:
Keystone species are animals that help manage other animal species by controlling population numbers and biodiversity within an ecosystem. The impacts of keystone species are usually greater than their numbers.
owls can be a great benefit to places where rodent populations are high. Dense urban areas often suffer from an abundance of rats and mice spreading disease, and rural agricultural communities have their crops consumed and soil eroded from burrowing voles and field mice. Without owls, and other top predators, rodent populations could explode and exacerbate the effects they produce.
Answer:
the owl is a keystone species, as many other birds. and it gives them the nutrients they need when they eat the bird and it mangeges the population of the other species:)

Convection in the troposphere causes
•wind •ocean currents •both wind and ocean currents •neither wind nor ocean
Explanation : The uneven heating of the regions of the troposphere by the sun ( the sun warms the air at the equator more than the air at the poles ) causes convection currents, large-scale patterns of winds that move heat and moisture around the globe. As air rises, expands, and cools, water vapor condenses and clouds develop.
