Understanding Detritivores and Decomposers

The video discusses detours, which are heterotrophs that consume dead matter, aiding in nutrient recycling in ecosystems. It highlights the role of decomposers like fungi and bacteria in breaking down organic compounds, making nutrients available for producers. Examples of detours include worms, millipedes, and sea stars, which help clean ecosystems by feeding on dead matter.

What is the primary role of detritivores in an ecosystem?

• To consume living plants

• To produce energy through photosynthesis

• To compete with decomposers for food

• To eat fragments of dead matter

Which of the following is NOT an example of a decomposer?

• Fungi

• Bacteria

• Worms

• Mushrooms

How do decomposers primarily break down dead organisms?

• By photosynthesis

• By consuming them whole

• By competing with detritivores

• By releasing digestive enzymes

What is a key difference between detritivores and decomposers?

• Detritivores produce their own food

• Detritivores consume living organisms

• Decomposers release digestive enzymes

• Decomposers are always larger than detritivores

Why are detritivores and decomposers crucial for the biosphere?

• They compete with each other for resources

• They prevent the accumulation of dead organisms

• They increase the number of predators

• They reduce the need for producers

Which of the following is an example of a detritivore?

• Algae

• Fungi

• Bacteria

• Sea star

What is the benefit of detritivores feeding on dead organic matter?

• They compete with producers

• They produce oxygen

• They increase the number of living organisms

• They help clean up the ecosystem
