What is the main difference between a food chain and a food web?
What is the main difference between a food chain and a food web?
- In a food chain, all organisms consume at all trophic levels, whereas in a food web, organisms consume only at one trophic level.
- A food chain represents a single energy flow pathway, while a food web shows the complex network of interconnected food chains. (correct)
- A food chain involves multiple interconnected food pathways, while a food web is a single linear pathway.
- A food chain involves both biotic and abiotic components, while a food web focuses only on biotic components.
What is the primary role of nutrient recycling in nature?
What is the primary role of nutrient recycling in nature?
- To regulate the population sizes of different species within an ecosystem.
- To prevent the accumulation of abiotic factors in an ecosystem.
- To ensure a constant supply of energy for all trophic levels in an ecosystem.
- To replenish essential nutrients in the soil for plant uptake and growth. (correct)
What is the significance of energy flow in ecosystems compared to nutrient cycling?
What is the significance of energy flow in ecosystems compared to nutrient cycling?
- Energy flows within individual organisms, while nutrients are transferred between different species.
- Energy is always recycled in an ecosystem, while nutrients flow unidirectionally.
- Energy flows only in one direction through trophic levels, while nutrients can move in cycles. (correct)
- Energy transfer occurs between biotic and abiotic components, but nutrient cycling only involves biotic factors.
