How did the appearance of the smallest creatures, such as microbes and bacteria, in earth's early history impact the geosphere "enriching the soil"?

they improve the aeration of the soil

Explanation:

The microbes play a very significant role in the solid development. The soil is a physiological aspect. In order for a soil to be classified as good soil, it should have several components. For example, it should have enough oxygen in it. This simply means the aeration of the soil should be good. In addition, the soil should have enough living material. The microbes improve the soil texture and other processes such as the nitrogen cycle and the other cycles that are necessary to keep the pH and other soil properties optimum.

The correct answer is: enriching the soil.

Explanation:

The appearance of small creatures such as microbes and bacteria impacted the Earth in all kinds of ways.

One of the ways these organisms impacted on the geosphere was by enriching the soils. Microorganisms are key participants in the fertility of the soil as they are involved in the nutrient cycles. Life as we know it wouldn't be possible if it weren't for the presence of these species, as they nourish our soil and give it its necessary characteristics for the production of food.

the correct answer in apex is tissue development, i know because i just had this question
