Step-by-step explanation:
By definition, a food chain represents a single pathway by which energy and matter flow through an ecosystem. This means that a food chain shows the eating patterns in an ecosystem. Food energy flows from one organism to another. We can represent this flow using arrows. The arrows are used to show the feeding relationship between the animals. In fact, the arrow points from the organism being eaten to the organism that eats it.
We can conclude that the correct answer is:
Answer:
The food chain describes who eats whom in the wild. This means that a food chain shows the eating patterns in an ecosystem. Then, the food energy flows from one organism to another. We can represent this flow using arrows. The arrows are used to show the feeding relationship between the animals. In fact, the arrow points from the organism being eaten to the organism that eats it. On the other hand, organisms in food chains are grouped into categories called trophic levels. these levels are divided into producers (first trophic level), consumers (second, third, and fourth trophic levels), and decomposers.
