An organism that gets energy by eating other organisms

Producer Consumer Decomposer Food chain

Correct Answer:

Consumer

Explanation:

In ecosystems, energy moves from producers to consumers. A consumer is an organism that gets energy by eating other organisms, whether plants or animals, so herbivores, carnivores, and omnivores fit this description. Producers, by contrast, make their own energy through photosynthesis or chemosynthesis, so they don’t rely on eating others. Decomposers obtain energy by breaking down dead material and waste, recycling nutrients rather than directly consuming living organisms. A food chain is a simple way to depict who eats whom, not an organism itself.
