What are the three things needed for an ecosystem to be self-sufficient? (able to keep going and stay balanced) | show 🗑
|
||||
show | Habitat is where an organism lives,
But a niche is all strategies and adaptations a species uses in its
environment, how it survives & reproduces, etc.
A species’ niche includes ALL interactions between the species and its habitat.
