Organisms that photosythesize get their energy from the sun

Fungi has a cell wall of chitin and cannot photosynthesize
Organisms that cannot produce their own oxygen gas include animals, fungi, and many bacteria. These organisms rely on other sources of oxygen, typically through respiration of oxygen produced by photosynthetic organisms like plants, algae, and cyanobacteria. Unlike autotrophs, which can photosynthesize and generate oxygen, these heterotrophic organisms obtain energy by consuming organic material.

Organisms in the plant kingdom include grasses, trees, ferns, mosses, and flowering plants. These organisms are characterized by their ability to photosynthesize and produce their own food.
There are no known animals that can photosynthesize. Photosynthesis is a process carried out by plants, algae, and some bacteria to convert sunlight into energy. Animals rely on consuming other organisms for energy.
The first organisms that were the first forms of life and were able to photosynthesize, were plankton. Most of our oxygen comes from the plankton living in the oceans. They play a big role in our everyday life, sharing that position with plants and all nature life (of plants).
