Question

How do materials cycle through biotic and abiotic parts of an ecosystem?

Accepted Answer

Living things are made of elements from the environment, which turn into complex compounds such as protein and fats. When animals eat each other, they are passed along. When they die, the elements are recycled and returned into the soil or air.
