Detailed explanation-1: -These protists are called filter feeders. They acquire nutrients by constantly whipping their tails, called flagellum, back and forth. The whipping of the flagellum creates a current that brings food into the protist. Other animal-like protists must “swallow” their food through a process called endocytosis.

Detailed explanation-2: -Protists eat a variety of foods, some of which are phototrophic, meaning they obtain their energy from sunshine. To obtain energy, other animal-like protists must consume organic substances. Slime moulds, for example, are fungi-like protists that degrade decomposing matter into useful nutrients.

Detailed explanation-3: -Protists get food in one of three ways. They may ingest, absorb, or make their own organic molecules. Ingestive protists ingest, or engulf, ba cteria and other small particles. They extend their cell wall an d cell membr ane around the food item, forming a food vacuole.

Detailed explanation-4: -The Kingdom Protista is divided into three groups, grouped by lifestyle: the protozoans, the slime molds and algae. Protozoans include all protists that ingest their food and live in aquatic habitats, such as ponds, drops of water in soil, or the digestive tracts of animals.

Detailed explanation-5: -Heterotrophic protists can’t make their own nutrients, so they have to ingest their food through diffusion or by actively catching prey using phagocytosis or structures such as peduncles and palliums.
