Not all organism that are born can be supported by the environment because organisms (blank) for resources

This blank space in this question is COMPETE

Explanation:

This question is describing natural selection, which is the theory proposed by Charles Darwin where he stated that organisms that are better suited for an environment will survive and reproduce better than others.

In the environment, resources such as food, water, mate etc are limited, hence, organisms must COMPETE for the available ones. In this case, organisms that are better adapted will triumph over others. Therefore, it is certain that not all organism that are born can be supported by the environment because organisms COMPETE for resources.

answer: "circumcision is a common procedure in which the skin covering the tip of the penis is surgically removed."

the species living around the vents are especially good at dispersal.  

deep-sea vent originates on the floor of the ocean when seawater circulates through hot volcanic rocks, usually situated where the new oceanic crust is being produced.  

biological dispersal refers to the movement of species from their location of birth to their site of breeding, or from breeding site to another. similarly, the oceanic dispersal refers to the movement of the species from one land mass to another by sea crossing.
