Which is the Correct Order of Progression

Question

Which is the correct order of progression?
A) ecosystem, community, population, organism
B) organism, community, population, ecosystem
C) organism, population, community, ecosystem
D) population, organism, ecosystem, community
E) community, organism, population, ecosystem

Accepted Answer

The correct order of progression is from organism to population, then to community, and finally the ecosystem. This is because an organism makes up a single living entity, while a population consists of individuals of the same species living in the same area. A community is made up of populations of different species, all interacting with each other in the same area. An ecosystem, on the other hand, consists of all the living and non-living components in an area and how they interact with each other.
