AP BIOLOGY

Detailed explanation-1: -Organisms belonging to Kingdom Fungi and Kingdom Animalia lack chlorophyll and thus cannot carry out photosynthesis, hence they show complete heterotrophic nutrition.

Detailed explanation-2: -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.

Detailed explanation-3: -Because fungi cannot produce their own food, they must acquire carbohydrates and other nutrients from the animals, plants, or decaying matter on which they live. The fungi are generally considered heterotrophs that rely solely on nutrients from other organisms for metabolism.

Detailed explanation-4: -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-5: -Within Domain Eukarya, kingdoms Fungi and Animalia are entirely heterotrophic, though most fungi absorb nutrients through their environment. Most organisms within Kingdom Protista are heterotrophic while Kingdom Plantae is almost entirely autotrophic, except for myco-heterotrophic plants.
