Question 3

How are living organisms dependent on the soil? Are organisms that live in water totally independent of soil as a resource?

Answer

Almost all living organisms are directly or indirectly dependent on soil. Plants obtain water, minerals from the soil and prepare food for animals.

On the other hand, other organisms that live in water are not totally independent of soil because the microbes growing on the soil in water are the primary producers which start the food chain and even microbes that live in the soil help in the decomposition of dead plants and animals in water to return the nutrients back to the water.
