In the context of decomposition, which of the following assertions is...
- The micro-organisms which convert the dead plants and animals to humus are known as decomposers.
- These microorganisms play an important role in the forest. The presence of humus ensures that the nutrients of the dead plants and animals are released into the soil.
- From there, these nutrients are again absorbed by the roots of the living plants and the dead animals become food for vultures, crows, jackals and insects.” In this way, the nutrients are cycled. So, nothing goes waste in a forest.
In the context of decomposition, which of the following assertions is...
Decomposition Process:
Decomposition is the process by which organic matter is broken down into simpler forms by decomposers like bacteria, fungi, and other microorganisms. This process plays a crucial role in recycling nutrients back into the ecosystem.
Assertion 1:
Decomposers feed upon the dead plant and animal tissues and convert them into a dark coloured substance called humus. This assertion is correct. During decomposition, decomposers break down complex organic matter into simpler substances. The end product of this process is humus, which is a dark-colored, organic material rich in nutrients. Humus improves soil structure, fertility, and water retention capacity.
Assertion 2:
These decomposers are helpful in maintaining the supply of nutrients for plants and animals. This assertion is also correct. Decomposers play a crucial role in nutrient cycling within ecosystems. By breaking down dead organic matter, they release essential nutrients like nitrogen, phosphorus, and potassium back into the soil. These nutrients are then available for uptake by plants, which are then consumed by animals, completing the nutrient cycle.
Therefore, both assertions are correct. Decomposers play a vital role in the decomposition process, converting dead organic matter into humus and maintaining nutrient supply for plants and animals.
