Natural selection is the process that result in the adaptation of an organism to environment by means of selectively reproducing changes in its genotype, or genetic constitution. It is the a key mechanism of evolution. Charles Darwin popularised the term "natural selection" contrasting it with artificial selection, which is intentional, whereas natural selection is not.
To make it simple, let's have a group of beetle composing of green and some are brown as an example. here, there is a variation in traits. Since the environment could not support continuous population growth, not all species can reproduce to their full potential. Green beetles can easily be eaten by other species like birds compared to brown beetles. The surviving brown beetles will then generate brown offsprings because their trait has a genetic basis. Since more brown beetles survive and becomes more common in the population, the process continues until all individuals will eventually be brown. so basically, if you have variation, differential reproduction, and heredity, you will have evolution by natural selection as an outcome.

Answer:
Plants.
Explanation:
Producers is an organism in an ecosystem that can make its own food. Plants use a process called "Photosynthesis" in order to make the food it needs to survive. Other organisms have to eat a different organism in order to survive,
Thus, the answer is (A)
Whenever two objects<span> are touching, they usually </span>exert forces on each other<span>. The </span>force<span> of gravity, on the </span>other<span> hand, is an </span>example<span> of a </span>force<span> that exists between </span>objects<span> without them having to be in contact. </span>Objects<span> with </span>mass exert forces on each other<span> via the </span>force<span> of gravity.
