Answer:
The correct option is B) ecosystem
Explanation:
Species can be described as a group or organisms that can interbreed and produce fertile offsprings.
A population can be described as the number of a particular type of species which are living in a given area at a particular time and they have the ability to breed and produce viable offsprings.
All the different populations living in an area at a particular time make up a community.
All the living communities with all the non-living factors (abiotic factors) of an area make up an ecosystem. Hence, ecosystem is the correct option.
