Question

Explain why a complex food web is better than a simple food chain for the survival of the community.

Answer 1

A complex food web is more important than a simple food chain for the survival of a community. The food web is more important because it is more intricate and adaptive than a food chain. A community houses many species. These species are dependent on each other for energy and food. So, there are multiple relationships of energy transfer involved.

A food chain is linear, which means that each predator has only one source of food. So the predator is vulnerable if the food source is depleted through disease or a change in environmental conditions. Whereas in a food web, each predator has many food sources. A complex food web provides multiple preys to species at a higher trophic level. As a result, a food web illustrates the feeding relationships between many species at different trophic levels in an ecosystem.

Answer 2

Step-by-step explanation:

A complex food web allows us to see more "pathways" and it is more complete, it shows us that if an species would go extinct there is a lower chance that the ecosystem would collapse.
