The term that refers to the particular way an organism obtains energy is trophic level.

Here's why:

* Trophic level describes an organism's position in a food chain or food web. It reflects how an organism gets its energy.

* Producers (like plants) are at the first trophic level, making their own food through photosynthesis.

* Consumers at higher trophic levels get their energy by consuming other organisms.
