Question

How do the populations in a community depend on each other

Answer 1

If you are talking about a community of like animals then they depend on each other because some animals could be in the same food chain to survive for food , if 1 species died out then most would be impacted by it and maybe die out too. Hope it makes sense and helps...!

Answer 2

Populations (all members of one type of organism living in an ecosystem) in a community (several populations living in an ecosystem) depend on each other because different species in various population could be sharing a similar food chain and depending on each other for survival.

if one population dies out in a community then all the populations that depend on that species for food may also die out. Hence a change in one population affects the entire community because all the populations in a community depends on each other.
