Answer 2

The CO2 content of the soil is a biotic factor.

• A biotic factor is a living object that organically changes its surroundings.
• Algae, and marine life such as fish and aquatic plants are few examples of organisms found in freshwater habitats. The interaction of biotic and abiotic elements leads to the formation of a specific ecosystem.
• The soil's total CO2 level is a biotic component naturally affecting the organic matter and living things that make up the soil.
• The amount of carbon dioxide in the air is governed by the equilibrium among biological processes that produce it, such as respiration, and those that use it, such as photosynthesis.
• The amount of carbon dioxide in the soil will depend on a number of elements, including the degree of aeration, root respiration, water content, and soil microbes.
