In summary, decomposers are not typically shown in food chains or food webs because they are responsible for breaking down dead materials and recycling nutrients rather than being part of the direct flow of energy. The main difference between a "pyramid of energy" and a "pyramid of biomass" is that the former considers the amount of energy released when a specific mass of an organism is burnt, while the latter considers the weight of the completely dehydrated organism.

Decomposers may be represented in the food chain (reference)

uuummm... actually they should be shown coz they are part of the energy cycle, i.e they release the energy from dead materials back to the surrounding, hence completing the cycle...

pyramid of energy is more representative as compared to the pyramid of biomass. the pyramid of energy considers the amount of energy liberated whe a specific mass of that organism is burnt while the pyramid of biomass considers the weight of the completely dehhydrated organism.
 

1. What are decomposers?

Decomposers are organisms that break down dead organic matter, such as dead plants and animals, into simpler substances that can be recycled in the environment.

2. Where can decomposers be found?

Decomposers can be found in all ecosystems, including on land and in water. They are present in soil, on the surface of plants, and in bodies of water.

3. What are some examples of decomposers?

Some examples of decomposers include bacteria, fungi, worms, and insects. These organisms play a crucial role in the decomposition process and help to recycle nutrients in the environment.

4. How do decomposers break down organic matter?

Decomposers break down organic matter by secreting enzymes that break down complex molecules into simpler substances. These substances are then absorbed by the decomposers and used as energy for their own growth and reproduction.

5. What is the importance of decomposers in an ecosystem?

Decomposers play a vital role in maintaining the balance of nutrients in an ecosystem. They break down dead organic matter and return essential nutrients, such as nitrogen and phosphorus, back into the soil, which can then be used by plants for growth. Without decomposers, the environment would become overwhelmed with dead organic matter and essential nutrients would be locked away, leading to a decrease in plant growth and overall biodiversity.
