A study based on food supply data shows that humans score a 2.21 on a scale of 1 to 5, indicating an omnivorous diet similar to pigs and anchovies. The trophic level varies widely across countries and regions, and is linked to development, nutrition and environmental impacts.

An apex predator, also known as a top predator, is a predator [a] at the top of a food chain, without natural predators of its own. [6] [7] Apex predators are usually defined in terms of trophic dynamics, meaning that they occupy the highest trophic levels.
A food chain is a linear network of links in a food web, often starting with an autotroph (such as grass or algae ), also called a producer, and typically ending at an apex predator (such as grizzly bears or killer whales ), detritivore (such as earthworms and woodlice ), or decomposer (such as fungi or bacteria ). It is not the same as a food web.
