Question

A community of organisms and the physical environment it occupies are known together as a(n):________

a. species.
b. community.
c. population.
d. ecosystem.

Answer 1

Answer: Ecosystem

Explanation: I believe it is an ecosystem because a species is a group of one specific kind of organism. A population only refers the number of species in a community or ecosystem and a community only refers to living organisms not the environment. A ecosystem usually refers to both organisms (biotic) and environment (abiotic).
