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

Answer:

All living organisms are directly or indirectly dependent on soil. Plants obtain water, minerals from the soil and prepare food for animals,                                   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 other microbes that live in soil help in the decomposition of dead plants and animals in water to return the nutrients back to the water.
