species at the top of the food chain, with no predators of its own. Also called an alpha predator or apex predator. trophic level. noun. one of three positions on the food chain: autotrophs (first), herbivores (second), and carnivores and omnivores (third).
What does bottom of the food chain mean?
In many ecosystems, the bottom of the food chain consists of photosynthetic organisms (plants and/or phytoplankton), which are called primary producers. The organisms that consume the primary producers are herbivores: the primary consumers. Secondary consumers are usually carnivores that eat the primary consumers.
Are we at the top of the food chain?
At the top of the scale are meat-eaters that don’t have any predators themselves, such as polar bears and orca whales.

Why are humans on top of the food chain?
Humans are said to be at the top of the food chain because they eat plants and animals of all kinds but are not eaten consistently by any animals. The human food chain starts with plants.
