Answers
Answer:
organisms contribute a lot in the formations of soils.
Explanation:
when the organisms died their body decomposed in the soil and increase the soil level. animals waste materials comes out from their body and mixes in the soil and increase the soil level. many plants are broken down by the natural calamities and decompose on the soil and increase the soil level .
Answer:
Living organism contribute to the formation of soil by performing biological weathering. In biological weathering, the living organisms secrete chemical secretions that help in the breakdown of large rocks into smaller fragments. Typical examples of organisms that help in soil formation are Lichens and Bryophytes.
Lichens induce biological weathering by extracting minerals from the rocks, which results in the formation of small cervices that serve as the site for soil formation.
Bryophytes can readily grow in the cervices formed by lichens and further deepen the cervices. These deeper cervices form cracks. In due course of time, because of growth of bigger plants, rocks eventually pulverise and form soil.
