Questions and Answers
Explain the role of detritivores and decomposers in an ecosystem.
How does composting demonstrate the concept of matter being recycled in an ecosystem?
Answer: Composting is an excellent example of matter being recycled in an ecosystem. In composting, organic matter such as food scraps, yard waste, and paper products are collected and broken down by a combination of detritivores and decomposers, such as earthworms, bacteria, and fungi. The resulting compost is rich in nutrients and can be used as a natural fertilizer for plants. This process demonstrates the recycling of matter, as the organic matter that would have otherwise been discarded is instead broken down and repurposed as a valuable nutrient source for new plant growth.
Study Notes
- Detritivores and decomposers recycle in an ecosystem.
- They eat dead plants, animals, and animal wastes.
- Detritivores break up organic matter into smaller pieces.
- Decomposers break down smaller pieces into simple substances.
- These substances are left in the soil as nutrients for plants.
- Decomposers convert biotic elements into abiotic elements.
- They allow matter to be recycled and reused by other organisms.
- Composting is a perfect example of matter being recycled.
- Earthworms and other detritivores break down decaying matter.
- Bacteria, fungi, and other decomposers further break down matter into nutrient particles.
