Wildebeest and red-billed quelea engage in resource partitioning, where each uses a different
part of the grass. explain how this works.

In an environment where resources such as food are being depleted, organisms within a species and organisms belonging to different species need to find a way in which they can coexist and survive in the environment. This is done by the organisms so in order to avoid competition. Resource partitioning is a method that organisms use for survival by dividing their resources so that there is lesser competition.

The wildebeest and the red-billed quelea are also using this phenomenon in order to survive. They have divided their part of the grass so that there is lesser competition and both of the species are able to coexist.

i believe the correct answer from the choices listed above is the first option. the scientists need to look at the   validity of data, claims, hypotheses, and observations before  developing an argument. they base their arguments on facts that are present and they make sure they have proofs. 

explanation:

organisms that are both used in toothpaste as well as cause malaria are protista and monera.
