Frequently Asked Questions

Why do we call plants producers and animals consumers?

Plants produce food from sunlight through photosynthesis. They create chemical energy that all other organisms depend on. Animals consume this energy by eating plants or other animals. The terms reflect the role each organism plays in energy flow.

Can an organism belong to more than one trophic level?

Yes, omnivores eat both plants and other animals. Humans are omnivores who can function as primary consumers when eating vegetables and as secondary consumers when eating meat. An organism that eats both plants and herbivores spans multiple trophic levels.

How many trophic levels can a food chain have?

Most food chains have 3-4 trophic levels. Rarely, they might have 5. The limitation is energy loss. Since only 10 percent of energy transfers to the next level, by the fourth level only 0.1 percent of the original energy remains, which is usually not enough to sustain a population.
