Q:

Which of the following is an Abiotic factor?

A) Plants B) Water
C) Consumers D) Animals

Answer:   B) Water



Explanation:

Abiotic and biotic factors are what make up an ecosystem.

 

Abiotic factors are all nonliving components of an ecosystem. These factors include chemical and geological features such as water or lack of water, soil, rocks, and minerals. Other abiotic factors include physical components such as the temperature and weather affecting the ecosystem.


The biotic factors in an ecosystem include all living things. All plants, animals, fungi, protists, and bacteria within an ecosystem make up that system's biotic factors. The biotic factors can be broken down further into producers, consumers, and decomposers.

The biotic factors present in an ecosystem are highly dependent on the abiotic factors that are present. Even slight changes to either factor can have a major consequence upon the system as a whole.
