Question

Micro organisms acts upon the dead plants to produce
A. Sand
B. Mushrooms
C. Humus
D. Wood

Answer 1

Hint: The microscopic species that occur as unicellular, multicellular, or cell clusters are microorganisms or microbes.

Complete Answer:
- Microscopic species are present all over us and also within our bodies, usually known as microorganisms or microbes. The 'Microbes' group contains a wide number of species, including bacteria, fungi, viruses, algae, archaea and protozoa.
- The vast majority of microbes on earth do not pose a particular danger to humans, plants or animals; in fact, they work together with humans to make the world go round, aiding decomposition, decay and even aiding us digest our food. There are, however, some microorganisms that have a detrimental effect on our lives, causing disease, unpleasant smells, and dangerous products and surfaces.
- The mechanism by which dead plants are turned into organic matter is referred to as decomposition. Decomposition is the first step in the body's recycling of the nutrients used by the dead plant.
- It is the method of breaking down the dead tissue and turning it into simpler organic farms, which are the food for many animals.
- The animals that conduct the decomposition process are referred to as detritivorous. The decomposition contributes to humus formation.

The correct answer is option(C) Humus.

Note: Decomposers in any ecosystem play an important role. Dead species can not be broken down without decomposers and recycled into other living matter. However, the reason that decomposers decompose is merely because they need to live. Decomposers are heterotrophic, which means that from ingesting organic material, they get their energy. In order to grow and replicate, a dead organism offers nutrients for decomposers such as bacteria and fungi to use, propagating their own organisms.
