Question

What are decomposers? List two consequences of their absence in an ecosystem.

Answer 1

Decomposers are organisms, such as bacteria, fungi, and certain insects, that break down dead organic matter (plants, animals, and other waste products) into simpler substances. They play a crucial role in recycling nutrients in the ecosystem, ensuring the flow of energy and maintaining the balance of the environment.
Two consequences of the absence of decomposers in an ecosystem:
• Accumulation of dead matter: Without decomposers, dead plants and animals would accumulate, leading to a build-up of organic waste in the environment.
• Nutrient deficiency: The absence of decomposers would disrupt the nutrient cycle, leading to a shortage of essential nutrients like nitrogen, phosphorus, and carbon, which are required for plant and animal growth.
