Explanation:
Abiotic factors include non-living environmental factors like wind, temperature and light, and chemical elements. These affect the biotic, living factors and shape their survival. For example high temperatures hinder the survival of organisms, and a lack of rainfall creates drought conditions where biotic factors die off due to food scarcity.
Biotic factors comprise the most important environmental components; bacteria, plants, animals, and fungi. The interaction between these living organisms can be classed into three groups; producers, like algae, plants, trees and grasses; consumers, which are plants that eat other animals or producers; and decomposers, that break down dead organic matter into soil.
