A functional classification of species that is based on feeding relationships. The number of steps an organism is from the start of the food chain is a measure of its trophic level. Food chains start at trophic level 1 with primary producers such as plants, move to herbivores at level 2, predators at level 3 and usually finish with carnivores or apex predators at level 4 or 5.
