An organism that needs to eat in order to get energy storage molecules such as starch and fat.

• A. Decomposer
• B. Consumer
• C. Producer
• D. Scavenger

Answer: (B)

Organisms that must eat to obtain energy are consumers. They rely on other organisms for energy-rich molecules, such as starch and fats, which come from the food they digest. Producers, like plants, make their own energy through photosynthesis and store it in molecules without needing to eat. Decomposers and scavengers also consume, but the key idea is that this organism gets its energy by feeding on others, not by making it themselves. Scavengers are a subset of consumers, but the broader term that fits the description best is consumer.
