Detailed explanation-1: -Heterotrophs are known as consumers because they consume producers or other consumers. Dogs, birds, fish, and humans are all examples of heterotrophs. Heterotrophs occupy the second and third levels in a food chain, a sequence of organisms that provide energy and nutrients for other organisms.

Detailed explanation-2: -There are four types of consumers: omnivores, carnivores, herbivores and decomposers. Herbivores are living things that only eat plants to get the food and energy they need. Animals like whales, elephants, cows, pigs, rabbits, and horses are herbivores. Carnivores are living things that only eat meat.

Detailed explanation-3: -The person who pays and purchases a product is called a consumer.

Detailed explanation-4: -Algae are producers, which prepare their food themselves through photosynthesis. They are not consumers.

Detailed explanation-5: -Omnivores are heterotrophs that consume both plants and animals. They include pigs, brown bears, gulls, crows, and humans. Omnivores actually fall on a continuum between herbivores and carnivores. Some omnivores eat more plants than animals, whereas other omnivores eat more animals than plants.
