Detailed explanation-1: -Carnivores are heterotrophs that consume animals; examples of heterotrophs include lions, polar bears, hawks, salmon, and spiders. Obligate carnivores (such as cats) are unable to digest plants so they can only eat animals.

Detailed explanation-2: -Fungi are heterotrophic. These organisms are plant-like in having cell walls but they lack chlorophyll (green pigment essential in photosynthesis). Protists (Kingdom Protista) that are heterotrophs include protozoans, certain nonphotosynthetic algae, water molds, and slime molds.

Detailed explanation-3: -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-4: -Bacteria, fungi, yeast, cows, dogs, humans are all heterotrophs. They all depend on plants and other animals for their food.

Detailed explanation-5: -All fungi are heterotrophic, which means that they get the energy they need to live from other organisms. Like animals, fungi extract the energy stored in the bonds of organic compounds such as sugar and protein from living or dead organisms. Many of these compounds can also be recycled for further use.
