An organism that makes its own food by the process of photosynthesis is known as an autotroph. Autotrophs are capable of converting sunlight energy into chemical energy to synthesize organic molecules, such as glucose. They accomplish this through the presence of organelles called chloroplasts, which contain a pigment called chlorophyll.

During photosynthesis, autotrophs absorb light energy from the sun using chlorophyll. This energy is then used to convert carbon dioxide and water into glucose and oxygen. The overall chemical equation for photosynthesis is:

6CO2 + 6H2O + light energy → C6H12O6 + 6O2

In simpler terms, carbon dioxide, water, and light energy combine to produce glucose (a form of sugar) and oxygen as a byproduct. Glucose serves as the primary energy source for the autotroph, while oxygen is released back into the atmosphere as a waste product.

Photosynthetic autotrophs are found in various forms, such as plants, algae, and some types of bacteria. Plants are the most commonly known autotrophs, utilizing their leaves as the main site for photosynthesis. Algae are photosynthetic organisms that are primarily found in aquatic environments, ranging from microscopic forms to larger seaweeds. Some bacteria, such as cyanobacteria, also have the ability to perform photosynthesis.

Overall, the ability of autotrophs to produce their own food through photosynthesis is crucial for maintaining the balance of ecosystems and providing energy for other organisms through the food chain.
