Question

this question will consider how the amount of overlap between niches might affect the overall ecosystems resilience to change. (how bad would it be for the ecosystem if one of the species was eliminated?) in scenario iii, there is overlap between the niches of the two species. because of this, if one of the species was removed, many of niche components because. in scenario i, there is overlap between the niches of the two species. because of this, if one of the species was removed, many of niche components because. based on the answers above, if there is more overlap in niches, ecosystems will be to survive changes because they have a \backup\ to get jobs done.

Explanation:

• For Scenario III: Looking at the diagram, the two - niche circles (for species A and B) overlap a lot. If one species is removed, since there is a large overlap, the other species can take over many of the niche components.
• For Scenario I: The two - niche circles overlap but not as much as in Scenario III. So, if one species is removed, the other species can take over some (but not as many as in Scenario III) of the niche components.
• For the general statement: More niche overlap means that when a species is lost, another species (with the overlapping niche) can fill in more of the ecological "jobs", making the ecosystem more resilient.

Answer:

• In Scenario III, there is a large overlap between the niches of the two species. Because of this, if one of the species was removed, many of niche components would still be filled because the other species has a large overlapping niche.
• In Scenario I, there is a moderate overlap between the niches of the two species. Because of this, if one of the species was removed, many of niche components would be partially filled because the other species has a moderate overlapping niche.
• Based on the answers above, if there is more overlap in niches, ecosystems will be more resilient to survive changes because they have a "backup" to get jobs done.
