The Miller-Urey experiment is important because this was considered as the breakthrough in the study of origin of life, as to where and how exactly life began on earth and that it was possible to form organic molecules from inorganic molecules.
The brain is most of the ape's main gimmicks, aside from the opposable thumb. It allows us to not die without claws, fangs, and other evolutionary benefits.
Answer:
Unlike matter, as energy flows through an ecosystem in one direction, from photosynthetic organisms to herbivores to omnivores and carnivores and decomposers, less and less energy becomes available to support life.
Explanation:
Primary producers use energy from the sun to produce their own food in the form of glucose, and then primary producers are eaten by primary consumers who are in turn eaten by secondary consumers, and so on, so that energy flows from one trophic level, or level of the food chain, to the next.
Energy is acquired by living things in three ways: photosynthesis, chemosynthesis, and the consumption and digestion of other living or previously-living organisms by heterotrophs.
Living organisms would not be able to assemble macromolecules (proteins, lipids, nucleic acids, and complex carbohydrates) from their monomeric subunits without a constant energy input.
