Trophic Levels and Feeding Relationships

Front

What is a secondary consumer?

Back

A secondary consumer is an organism that eats primary consumers (herbivores) in a food chain.

Front

What are omnivores?

Back

Omnivores are organisms that can consume both plants (primary producers) and animals (primary or secondary consumers).

Front

What is the shape of energy and biomass pyramids?

Back

Energy and biomass pyramids typically have a pyramid shape because the amount of biomass at each trophic level cannot exceed the energy available to support it.

Front

What is competition in ecological terms?

Back

Competition occurs when two or more organisms vie for the same resources in an ecosystem, such as food, space, or light.

Front

What is the second trophic level in a food chain?

Back

The second trophic level consists of herbivores, which are organisms that consume primary producers.

Front

Define primary consumer.

Back

A primary consumer is an organism that eats primary producers (plants) in a food chain.

Front

What is a producer in an ecosystem?

Back

A producer is an organism that can make its own food through photosynthesis or chemosynthesis, forming the base of the food chain.

Front

What role do carnivores play in a food chain?

Back

Carnivores are organisms that eat other animals, typically functioning as secondary or tertiary consumers.

Front

Explain the concept of trophic levels.

Back

Trophic levels are the hierarchical levels in an ecosystem, defined by how organisms obtain their energy, including producers, primary consumers, secondary consumers, and tertiary consumers.

Front

What is predation?

Back

Predation is an interaction where one organism (the predator) hunts and consumes another organism (the prey).
