When there are many organisms that live in the same area and have to compete for limited resources like food, water, and shelter, it is called competition.

When some organisms are better at competing than others, they may have an advantage and be more likely to survive and reproduce. The other options listed are not correct for this question. Immigration is when organisms come into an area from somewhere else. Symbiosis is when two organisms live together and both benefit from the relationship. Extinction is when all members of a certain species die out. Therefore, the correct answer to this question is option D, competition.
