Plants and algae that make their own food are called

• A. Omnivores
• B. Detritivores
• C. Primary Producers
• D. Decomposers

Answer: (C)

The main idea here is how energy enters an ecosystem through organisms that produce their own organic matter. Plants and algae are autotrophs, meaning they make food themselves—most commonly by photosynthesis, turning light energy into chemical energy stored in sugars. This ability to generate energy-rich biomass places them at the base of the food web as primary producers, supplying the energy and organic matter that all other organisms rely on. Primary producers form the foundation of ecosystems; herbivores feed on them, and predators feed on the herbivores and other consumers, transmitting energy up the chain. That’s why plants and algae that make their own food are called primary producers. The other terms don’t fit the role described. Omnivores eat both plant and animal matter; detritivores consume detritus and decomposing material; decomposers break down dead matter and recycle nutrients. They don’t primarily produce their own food, which is the defining feature of primary producers.
