The correct answer is C. food web.
A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another. A food web is a more complex system of interconnected food chains. In a food web, each organism is part of multiple food chains. This is because organisms can eat more than one type of food, and they can also be eaten by more than one type of predator.
A food link is a connection between two organisms in a food chain. It is a single step in the transfer of energy from one organism to another. For example, the link between a plant and a grasshopper is the grasshopper eating the plant.
A food pyramid is a diagram that shows the relative amounts of energy at each trophic level in a food chain. The base of the pyramid is the largest, and each level gets smaller as you go up. This is because there is less energy available at each higher level.
