Step 1:I'll solve this ecology problem step by step:
Step 2:: Understand the Role of Decomposers
Decomposers are organisms like bacteria and fungi that break down dead organic matter and waste products from other organisms. Their primary ecological function is to recycle nutrients back into the ecosystem.
Step 3:: Analyze the Nutrient Recycling Process
When organisms die or produce waste, decomposers break down these materials into simpler chemical components. This process releases essential nutrients like nitrogen, phosphorus, and carbon back into the soil and water, making them available again for primary producers like plants to use.
Step 4:: Evaluate the Answer Choices
Let's examine each option: A. They recover nutrients from dead matter and waste. ✓ CORRECT B. They feed the primary producers. (Partially true, but not their main role) C. They take in energy from inorganic compounds. (Incorrect) D. They provide nutrition directly to consumers. (Incorrect)
Step 5:: Explain the Importance of Nutrient Recycling
Decomposers are critical because they: - Break down complex organic molecules - Release nutrients back into the ecosystem - Prevent accumulation of dead matter - Support the continuous cycling of nutrients
Final Answer
Decomposers, such as bacteria, are important to an ecosystem's food web because they recover nutrients from dead matter and waste, enabling nutrient recycling and supporting ecosystem productivity.
