Answer:
Natural processes are interactions among plants, animals, and the environment. These interactions, which include photosynthesis , pollination, decomposition , and others, help create and shape natural communities.
Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways. ... These individuals then pass the adaptive traits on to their offspring. In the essence of Darwin's theory, natural selection will occur if three conditions are met. These conditions, highlighted in bold above, are a struggle for existence, variation and inheritance. In evolutionary theory, adaptation is the biological mechanism by which organisms adjust to new environments or to changes in their current environment. ... The idea of natural selection is that traits that can be passed down allow organisms to adapt to the environment better than other organisms of the same species.
