Answers
Answer:
2. Collectively, soil microorganisms play an essential role in decomposing organic matter, cycling nutrients and fertilising the soil. ... Soil microbes are of prime importance in this process. Soil microbes are also important for the development of healthy soil structure.
3. Apart from penicillin, the most important antibiotics from fungi are the cephalosporins (beta-lactams with similar mode of action to penicillin, but with less allergenicity) and griseofulvin (from Penicillium griseofulvum and related species) which is used to treat althlete's foot and related fungal infections of the skin.
4. Microorganism plays very important role in agriculture because the soil microbes (bacteria and fungi) are essential for decomposing organic matter and recycling old plant material. Some soil bacteria and fungi form relationships with plant roots that provide important nutrients like nitrogen or phosphorus.
5. Microorganisms are found everywhere in the environment and play a leading role in countless natural processes. Among other things, they operate the basic drug cycles that are necessary for the plants' supply of nutrients via the reaction of organic matter in soil.
