natural selection

Explanation:

Charles Darwin and Alfred Wallace, are the parents of the theory of evolution, which occurs by the process of natural selection.

In short, the theory of species evolution says that groups of living things pass on some characteristics from parent to child, and from one generation to the next, nature selects the individuals best suited to the environment in which they live. Thus, as the environment changes - with increasing or decreasing temperature and rainfall, for example - the more surviving and reproducing are those who are better able to feed, escape predators or find mates for breeding, among other skills. . This process is called natural selection and, over millions of years, the result is the emergence of new species, similar to the original but different in some crucial characteristics.

the element that provides strength to the exoskeletons of clams and oysters is phosphorus. this is so because calcium carbonate is the main component in the shells.

explanation:

kelp are large brown algae that live in cool, relatively shallow waters close to the shore. they grow in dense groupings much like a forest on land. these underwater towers of kelp provide food and shelter for thousands of fish, invertebrates, and marine mammal species.
