what would happen if:
grass died
Primary consumers would most likely die and since they died secondary consumers wouldn’t be able to survive, because they wouldn’t have any food
what would happen if:
snakes decreased
The predators of snakes would have less of a chance of survival, because there would be less snakes to hunt.
how do buildings harm ecosystems?
Because it gives less space for things such as green plants and grass to grow and producers are the most important, without it primary and secondary producers wouldn’t be able to survive.
