Which types of organisms are primarily responsible for recycling nutrients in a food web?
A
Decomposers
B
Primary consumers
C
Apex predators
D
Producers
Verified step by step guidance1
Understand the role of decomposers in a food web: Decomposers are organisms such as fungi and bacteria that break down dead organic matter and waste products, converting them into simpler substances like nutrients that can be reused by producers.
Examine the role of primary consumers: Primary consumers are herbivores that feed on producers (plants and algae). They do not recycle nutrients but rather transfer energy through the food web.
Analyze the role of apex predators: Apex predators are at the top of the food chain and consume other organisms. They do not recycle nutrients directly but contribute to population control within the ecosystem.
Understand the role of producers: Producers, such as plants and algae, use nutrients from the soil and water to create energy through photosynthesis. They rely on decomposers to recycle nutrients back into the ecosystem.
Conclude that decomposers are the primary organisms responsible for recycling nutrients in a food web, as they break down organic matter and return essential nutrients to the environment for use by producers.
