What is a foodchain A foodchain is the way that different living Biology Diagrams As the consummate omnivores, humans are predisposed to deep involvement in food webs. Humans prey upon animals at all trophic lev-els, use almost half of the terrestrial earth to raise livestock (1), consume a large fraction of thesea'splantsandanimals(2),andappropriate more than a quarter of terrestrial net primary productivity for food (3). A typical human food chain is three or four organisms long. Plants, or algae being the producer, are at the bottom of the food chain. Herbivores like cows, goats, pigs, and sheep, the primary consumer of the food chain, follow them. When humans feed on the primary consumers, they become secondary or apex consumers in this food chain.
But as far as the planet's food chain, we're technically not at the top of it. Actually, we're not even close. As the insanely-interesting new study by the -- deep breath -- Proceedings of the National Academy of Sciences of the United States of America points out, to be at the scientific "top of the food chain," a species must ingest only the
Humanity's Role in Food Chains: Unveiling the Impact and Consequences Biology Diagrams
It's a platitude that we've all heard dozens of times, whether to justify our treatment of other species or simply to celebrate a carnivorous lifestyle: humans are the top of the food chain
Role of Humans in Food Chains. Humans play significant roles in food chains, both directly and indirectly. As apex predators, humans have a substantial impact on the balance of ecosystems and the distribution of species within food chains. Directly, humans participate in food chains through hunting, fishing, and agriculture. Humans are typically at the top of food webs as apex predators. This is because humans consume both plant and animal products. They eat primary producers (like plants) and various levels of consumers (like cows, pigs, chickens, fish, etc.). Additionally, there are very few predators that prey on humans, which is why they are considered at the top of the food chain.

In the new study, ecologists specifically calculated human's trophic level โ a number between 1 and about 5.5 that tells you how much energy it takes to make a species' food.. Plants and algae
