Question

Which of the following describes a potential outcome of competition, as discussed in your textbook? Select all correct answers.

A.	If two species use the same limiting resource, they can coexist if they partition that resource such that they are using it in different ways

B.	Resource partitioning in sympatry can lead to character displacement, given enough time, which means that two species will look more different when found together than when they live apart

C.	If two species use the same limiting resources in the same way, the worse competitor can be excluded from sympatric areas (meaning, areas where they are both found)

D.	If two species compete for a limiting resource, natural selection can cause the worse competitor to become the better competitor, given enough time

Answer 1

The answer would be- A ,B and C

Option D is incorrect. Worst competitor will not be able to survive. Better competitor will survive in nature by the course of time.

And option A,B and c all describes potential outcome of competition. Potential outcome of competition is the outcome after two species engages in competition. It can result in -

• Resource partitioning- using same resource in different ways.
• Character displacement-. Changing features to minimize competition in the same environment.
• Competitive exclusion- where worst competitor is excluded.
