Question

Could a fallen tree in a forest be regarded as an entire ecosystem? Explain

Answer 1

Answer:

Yes

Explanation:

dead wood that falls into a stream continues to perform an ecological role.  It provides habitat and a source of food for aquatic animals and plants. It controls current velocities and helps prevent scouring of the streambed.  It stabilizes stream banks, and provides waterfalls and pools important for fish feeding and spawning.
