A food chain in an ecosystem includes cherry trees, birds and cats. Birds eat cherry and cats eat birds. If the population of cats decrease, how will this affect the population of cherry trees?
Cherry trees will decrease because there will be more birds to eat them.
What would happen if all producers in an area disappeared?
Consumer populations would increase because more sunlight could get through
decomposer populations would increase because more sunlight can get through
consumer populations would decrease because producers provide them with water
Consumer populations would decrease because producers provide them with energy.
Consumer populations would decrease because populations provide them with energy.

This is how plants return water back to the into the environment.
What is transpiration.
Why does a bicycle slow down when the brakes are applied?
