Verified step by step guidance1
Understand the concept of a food web: A food web is a complex network of interconnected food chains in an ecosystem, showing how different organisms are related through feeding relationships.
Identify the role of decomposers: Decomposers are organisms, such as bacteria and fungi, that break down dead or decaying organisms. They play a crucial role in nutrient cycling.
Recognize the process of decomposition: Decomposers break down organic matter into simpler substances, releasing nutrients back into the soil and making them available for primary producers like plants.
Differentiate decomposers from other roles: Unlike primary producers that create energy through photosynthesis or top predators that consume other animals, decomposers focus on recycling nutrients.
Conclude the primary role: The main function of decomposers in a food web is to break down dead organisms and recycle nutrients back into the ecosystem, supporting the growth of primary producers and maintaining ecological balance.
