Final answer:
Consumers are organisms that obtain their energy from other organisms. They are grouped into herbivores, carnivores, and omnivores based on their food sources.
Step-by-step explanation:
Consumers and Decomposers
Recall that producers make their own food through photosynthesis.
But many organisms are not producers and cannot make their own food.
They must get their energy from other organisms.
They must eat other organisms, or obtain their energy from these organisms some other way.
The organisms that obtain their energy from other organisms are called consumers.
All animals are consumers, and they eat other organisms.
Fungi and many protists and bacteria are also consumers.
But, whereas animals eat other organisms, fungi, protists, and bacteria "consume" organisms through different methods.
