Which term describes the linear sequence showing how one organism obtains its food from another in an ecosystem?

Explanation:
The idea being tested is how energy travels in ecosystems along a straight line from one organism to the next. A food chain describes that linear sequence of who eats whom, such as grass (producer) being eaten by a rabbit (primary consumer), which is then eaten by a fox (secondary consumer). This makes it the best fit for the description because it highlights a single path of energy transfer. A food web would show many interconnected chains, which is more complex. A biome is a large climatic region, and competition is about organisms contending for the same resources. Therefore, the term is food chain.
