Detailed explanation-1: -Heterotrophs are the organism that are not able to synthesize their own food. Thus they are dependent on other organisms for food. Animals depend on plants or other animals for food. Hence they are heterotrophs.
Detailed explanation-2: -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-3: -Which of the following statements best describes the relationship between autotrophs and heterotrophs? Autotrophs produce their organic molecules from CO2 and other inorganic molecules, whereas heterotrophs obtain their organic molecules from compounds produced by other organisms.
Detailed explanation-4: -Animals cannot make food on their own. They depend on plants for their food either directly or indirectly. And therefore, nutrition in animals is said to be heterotrophic.
Detailed explanation-5: -Autotrophic nutrition: In this type of nutrition, the plants and other photosynthetic organisms prepare their own food with the help of sunlight, water and carbon dioxide. Heterotrophic nutrition: The animals cannot prepare their own food. Therefore, they have to rely on other animals for nutrition.
