A food chain is a sequence of events in nature in which one organism eats another, and is then eaten by another in turn. All food chains start with the primary source, either the sun or chemicals produced by hydrothermal vents deep in the ocean. When an organism uses those sources to make food, it starts the food chain.

Answer 2

Answer:

A food chain's length is restricted to just 3 or 4 steps due to energy loss. ... Consequently, the shorter the food chain, the more energy that is available to the final consumer. A shorter food chain is also considerably more efficient as less energy is lost.
