Answer:
The scientific study of life, called <u>Biology</u><u>, </u>can be organized around several themes. As the biological hierachy builds from molecules on up to ecosystems, each level has <u> emergent properties</u> that result from interactions among component parts. Life's basic unit of <u>structure and function</u> is the cell, which occurs in two basic forms- prokaryotic and eukaryotic . As organisms interact with the environment, <u>nutrients and chemicals</u><u> </u>cycle within an ecosystem, while energy flows one way from sunlight -> chemical energy -> heat. According to the core theme of <u>evolution </u>all of life is related by common descent. Life was diversified as <u>natural selection</u> had led to the gradual accumulation of adaptations that fit populations to the environment.
Explanation:
Emergent properties- Properties that is exhibited by a group of individuals as a result of interaction among them.
Evolution- the process by which populations develop new characteristic and become more efficient than their ancestors.
