What is the role of decomposers in the pond ecosystem?

They release dead matter for reuse by autotrophs through decomposition and mineralization.

The correct answer is (c) They release dead matter for reuse by autotrophs through decomposition and mineralization.

Decomposers play a crucial role in the pond ecosystem by breaking down organic matter and releasing nutrients back into the environment. Their main role is decomposition, which involves the breakdown of dead plant and animal material into simpler inorganic compounds.

When plants and animals die in the pond ecosystem, their organic matter, such as leaves, algae, or dead organisms, accumulates. Decomposers, including bacteria, fungi, and other microorganisms, feed on this organic matter. They break it down into simpler compounds, such as carbon dioxide, water, and various nutrients like nitrogen and phosphorus.

Through decomposition, decomposers release these nutrients from the organic matter, making them available for reuse by autotrophs, such as plants and algae, in the pond ecosystem. This process is essential for nutrient cycling and the sustainability of the ecosystem. It ensures that the nutrients tied up in dead matter are recycled and can be used by other organisms for growth and reproduction.

Decomposers also contribute to mineralization, which is the process of converting organic matter into inorganic forms. By breaking down complex organic compounds, decomposers release inorganic minerals that can be absorbed by plants and other organisms.

In summary, decomposers in the pond ecosystem help break down dead organic matter through decomposition and mineralization. By doing so, they release nutrients back into the ecosystem, allowing autotrophs to utilize them and maintaining the flow of energy and nutrients through the food web.
