How does natural selection contribute to total biodiversity?

Natural selection says that either they evolve differently and increase their biodiversity or they die. Both wouldn't have enough food to survive so animals with those traits would become less and less common. ... Natural Selection can also decrease the biodiversity.

Increase their biodiversity or they die

Explanation:

Both wouldn't have enough food to survive so animals with those traits would become less and less common. ... Natural Selection can also decrease the biodiversity.

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
