Question

when an ecosystem contains many different species, there are usually a high number of links in its food web. how does this affect the sustainability of the ecosystem? a. typically, if one link in the food web is added, the ecosystem will change its location. b. typically, if one link in the food web is removed, the ecosystem will no longer exist. c. typically, if one link in the food web is removed, the ecosystem will remain stable. d. typically, if one link in the food web is added, the ecosystem will destabilize.

Explanation:

A more diverse food - web with many links provides redundancy. This means that if one species (link) is removed, other species can often fill its ecological role, helping the ecosystem remain stable. Adding a link usually does not cause immediate destabilization, and an ecosystem doesn't change location due to a single food - web link addition. Also, an ecosystem won't cease to exist just because one link is removed.

Answer:

C. Typically, if one link in the food web is removed, the ecosystem will remain stable.
