Final answer:
A food chain is a linear sequence of energy transfer in which organisms eat one another, with energy decreasing at each trophic level.
Step-by-step explanation:
The term used to describe a linear sequence in which energy is transmitted from one organism to the next as each organism eats another organism is a food chain. In a food chain, energy flows from the producer, the organism that produces its own food, to the consumer, the organism that eats the producer, and further to other consumers. Each step in the food chain is known as a trophic level, with energy decreasing as it moves up the chain. This concept is represented by an energy pyramid, which shows the amount of energy available at each trophic level.
