An association of individuals of different species living in the same habitat and having functional interactions is what?
Which of the following best explains the connection between increased competition and the evolution of a species by natural selection?
Individuals migrate to another area in order to avoid competition for limited resources in the current ecosystem.
Individuals that have traits that allow them to outcompete others survive better and produce more offspring.
Individuals must become stronger to compete for resources, and this increased strength is passed on to the next generation.
Individuals that must compete for limited resources are more likely to have diseases that cause mutations.

- Which of the following statements is consistent with the principle of competitive exclusion?
