19 de oct. de 2023 · The food chain describes who eats whom in the wild. Every living thing—from one-celled algae to giant blue whales ( Balaenoptera musculus )—needs food to survive. Each food chain is a possible pathway that energy and nutrients can follow through the ecosystem. For example, grass produces its own food from sunlight.
Food Chains. A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another. Each organism in a food chain occupies a specific trophic level (energy level), its position in the food chain. The first trophic level in the food chain is the producers. The primary consumers (the herbivores that eat producers) are the second trophic level.
Food chains give us a clear-cut picture of who eats who. However, some problems come up when we try and use them to describe whole ecological communities. For instance, an organism can sometimes eat multiple types of prey, or be eaten by multiple predators, including ones at different trophic levels.
