Explanation of Solution

In the ecological hierarchy, the biosphere consists of the all the ecosystems. The entire ecosystem on the earth comes under the biosphere. The ecosystem is the community along with the abiotic factors. The community is the group of the entire population present in a region interacting with one another. The population is the group of interbreeding individuals of a species present in a particular region at a particular time period. So, it can be said that the ecosystem comprise all the population and the abiotic factor present in a region.

Conclusion

The populations, ecosystem, and the biosphere are the important higher levels of biological organization. The biosphere comprises the entire ecosystem and the ecosystem comprises the entire population along with their abiotic factors.
