Trophic levels: These refer to different positions in a food chain where organisms obtain their energy. For example, plants occupy the first trophic level as primary producers.

Energy pyramid: This is a graphical representation that shows how energy decreases at each trophic level in an ecosystem. It demonstrates the diminishing amount of available energy as you move up the food chain.

Biomagnification: This process occurs when toxins or pollutants become more concentrated as they move up through trophic levels in a food chain.
