Answer:
The correct option is ALL THE REDWOOD TREES THAT LIVES IN A FOREST.
Step-by-step explanation:
In the study of the ecosystem, population refers to a group of living organisms that belong to the same species and which live in the same area and interact with one another. In the options given, option A is wrong because a spider and a fly are not the same specie. Option C is wrong because all the plants that live near each other in a forest can not be the same species. Option D is wrong because all the coyotes on earth are not living in the same environment, where they can interact with one another. Option E is wrong because the earthworm that live in a grassland and the one that live in the forest are not living in the same environment and therefore can not interact.
