Answer:
A
Producers, or autotrophs, make their own organic molecules. Consumers, or heterotrophs, get organic molecules by eating other organisms. A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another
B ,Producers, such as plants and algae, use energy from sunlight to make food energy by combining carbon dioxide and water to form organic matter. This process begins the flow of energy through almost all food webs.
C,The herbivore then becomes prey their energy is transferred to the predator. When consumed some of the energy is transferred but some of the energy is lost at each link in the chair (or trophic level). In the above example, the grass loses some energy by respiration, the rabbit loses energy by heat and waste.
hope it helps ,this my own opinion only if you don't think this is right then it's alright you can find another answer better than mine
