Photosynthesis is the process by which plants, algae, and some bacteria convert light energy into chemical energy, which is stored in the form of sugars.

Here's a breakdown of the organisms that undergo photosynthesis:

* Plants: All plants, from tiny mosses to towering trees, use photosynthesis to create their food.

* Algae: These diverse organisms, ranging from single-celled phytoplankton to giant kelp, are also photosynthetic.

* Cyanobacteria: These bacteria are often called "blue-green algae" and are incredibly important for producing oxygen in our atmosphere.

It's important to note that not all organisms on Earth are photosynthetic. Animals, fungi, and most bacteria obtain energy by consuming other organisms.
