I think the correct answer from the choices listed above is option A. A single population is made of multiple organisms. In biology, population is a group of individuals which belongs to the same species that lives in the same area. Hope this answers the question.
I’m sorry, what’s the question?
The answer is: Ecological Succession
STEPS:
1.) Bare rock (there is no grass at this point).
2.) Lichens (lichens begin to appear).
3.) Small Plants & Lichens (small plants begin to grow & the lichens are spreading).
4.) Grasses (grass starts to grow in certain spots).
5.) Shrubs & Grasses (the grass has covered, at least the majority, of the ground and shrubs begin to appear).
6.) Trees (the shrubs have grown into trees that are tall enough to provide shade)
7.) Animals (the animals return or new animals appear).
