Question

Quizplus · Accepted Answer

Trophic levels refer to the levels of a food web based on an organism's source of nutrition, with primary producers at the first trophic level, followed by primary consumers (herbivores) at the second, and so on up to apex predators at the highest trophic level. This classification system is based on the flow of energy and nutrients through the food web. Choices A and B (niche and guild) are related to the specialized roles and functions of organisms within an ecosystem, while choice D (predation) concerns the relationship between predator and prey, which is a key factor in shaping food webs.
