They break down dead organic matter, recycling nutrients.
B
They consume primary producers.

Verified step by step guidance1
Understand the role of decomposers in an ecosystem: Decomposers are organisms, such as bacteria and fungi, that break down dead organic matter.
Recognize the importance of nutrient recycling: By breaking down dead organisms, decomposers release nutrients back into the soil, making them available for use by plants and other primary producers.
Differentiate decomposers from other organisms: Unlike primary producers, decomposers do not produce energy through photosynthesis. Instead, they obtain energy by consuming dead organic material.
Consider the ecological impact: Decomposers play a crucial role in maintaining the balance of ecosystems by preventing the accumulation of dead matter and facilitating nutrient cycling.
Clarify misconceptions: Decomposers do not create new habitats or consume primary producers; their primary function is to recycle nutrients by breaking down dead organic matter.
