Key Concepts

Omnivory

Omnivory is the dietary habit of consuming both plants and animals. This allows organisms, like humans, to occupy multiple trophic levels simultaneously. Being omnivorous means that an organism can act as a primary consumer when eating plants, and as a secondary consumer when eating animals that have fed on plants.

Secondary Consumers

Secondary consumers are organisms that feed on primary consumers. They play a role in energy transfer by consuming herbivores, and are often carnivorous or omnivorous. The presence of secondary consumers is an important component in understanding the complexity of food webs.

Trophic Levels

Trophic levels refer to the hierarchical positions in an ecological food chain, where each level represents a step in the flow of energy and nutrients. These levels include primary producers, which create energy through photosynthesis; primary consumers, which are herbivores; secondary consumers, which are carnivores or omnivores that eat the primary consumers; and higher-level consumers, which include top predators.

Primary Consumers

Primary consumers are organisms that obtain their energy by feeding directly on primary producers, such as plants. They are a critical link in food chains, transferring energy from the base of the ecosystem (producers) to higher trophic levels.
