In an ecosystem, what role do decomposers play?
A
They break down dead organic matter, recycling nutrients.
B
They produce energy through photosynthesis.
C
They are the primary consumers of herbivores.
D
They compete with primary producers for sunlight.
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 plants and other producers.
Differentiate decomposers from other roles: Unlike producers, decomposers do not produce energy through photosynthesis. Instead, they obtain energy by breaking down organic material.
Identify the relationship with other organisms: Decomposers are not primary consumers of herbivores; rather, they consume dead organic matter from all trophic levels.
Clarify competition dynamics: Decomposers do not compete with primary producers for sunlight, as they do not rely on photosynthesis for energy.
