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.

The short answer to it is no, humans are not autotrophs. All entities are broadly classified into one of the two categories – autotrophs (ones who make their own food) and heterotrophs (one who cannot produce its own food and depends on others for its nutritional requirements).

Algae, along with plants and some bacteria and fungi, are autotrophs. Autotrophs are the producers in the food chain, meaning they create their own nutrients and energy. Kelp, like most autotrophs, creates energy through a process called photosynthesis.

grass is an example of an autotroph because it uses sunlight to produce food using photosythesis and grows.

Autotrophs get their energy from the sun, while heterotrophs get their energy from eating other organisms. An example of an autotroph is a daisy, and an example of an autotroph is a dog.

Heterotrophic or Autotrophic: The zebra is Heterotrophic, and this is because the zebra does not have the ability to go through photosynthesis, meaning that it does not make its own food using energy (sunlight). This mammal has to hunt for its food, just like we do.

Conversely animals like cow, dog, lion, horse, etc. are said to be heterotrophic as they cannot prepare their own food and depends directly or indirectly on others for their nutrition.

frogs are heterotrophs, they are not producers meaning they do not make their own food.

Adult frogs generally have a carnivorous diet consisting of small invertebrates, but omnivorous species exist and a few feed on plant matter. Frog skin has a rich microbiome which is important to their health.

Wolves are categorized as either secondary or tertiary consumers. However, in many food chains, wolves are apex predators.
