Protista knowledge. Autotrophic protista. They can perform photosynthesis and mainly consist of unicellular algae. They can be divided into a number of systematic groups according to the shape of their cells and the type of photosynthetic pigments they use.
They do not need a living source of energy or organic carbon. Autotrophs can reduce carbon dioxide to make organic compounds for biosynthesis and also create a store of chemical energy. Most autotrophs use water as the reducing agent, but some can use other hydrogen compounds such as hydrogen sulfide.Phototrophs (green plants and algae), a type of autotroph, convert electromagnetic energy from sunlight into chemical energy in the form of reduced carbon.hus, heterotrophs â all animals, almost all fungi, as well as most bacteria and protozoa â depend on autotrophs, or primary producers, for the energy and raw materials they need. Heterotrophs obtain energy by breaking down organic molecules (carbohydrates, fats, and proteins) obtained in food.
