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.

Detailed explanation-2: -“Heterotroph is an organism that is unable to synthesize its own food, and therefore, has to rely on other sources, specifically plant and animal matter.” All animals and non-photosynthetic plants are classified as heterotrophs since they are unable to prepare food.

Detailed explanation-3: -Humans do not possess the physiological mechanism to produce their own food from the raw materials in their surroundings like the plants. Hence, humans consume plants and other animals to fulfill their energy needs. As they derive food or energy from other sources they are referred to as heterotrophs.

Detailed explanation-4: -True. Plants that manufacture their own food are called heterotrophs.

Detailed explanation-5: -The three types of heterotrophs are herbivores, omnivores and carnivores, and detritivores.
