Question

Which of the following represents the proper ecological hierarchy?

• A. Population --> community --> ecosystem --> biosphere
• B. Ecosystem --> community --> population --> biosphere
• C. Population --> ecosystem --> community --> biosphere
• D. Biosphere --> ecosystem --> population --> community
• E. Community --> population --> biosphere --> ecosystem

Answer 1

The correct option is A Population --> community --> ecosystem --> biosphere

An ecosystem is all the living things in an area interacting with all of the abiotic parts of the environment.

A population is a summation of all the organisms of the same group or species, which live in a particular geographical area, and have the capability of interbreeding.

The community is an interacting group of various species in a common location.

The biosphere is an irregularly shaped, relatively thin zone in which life is concentrated on or near the Earth's surface and throughout its waters. Thus, the correct answer is option A.
