They use carbon dioxide to power photosynthesis, which uses solar energy to create food, using chloroplasts and chlorophyl. This gives them a useable source of energy to live and grow, and they release oxygen which we breathe. 10% of this energy is passed onto consumers when they digest the plant.
The microscopic algae are unicellular, colonial and filamentous forms of organisms.
Algae
Certain algae is unicellular and microscopic. Multicellular algae can be microscopic, but often are not. Seaweed is an example of algae that is a single multicellular organism and not microscopic.
The organisms need plants, algae and bacteria for their nourishment. This ensures their survival.
Bacteria or bacterium is a microscopic single celled simple plants some are harmful and some are helpful. Algae is a simple chlorophyll-bearing organisms lacking true stems, roots, or leaves. Unicellular and multicellular; divided into blue-green algae (similar to bacteria) and all other algae.
Plankton are microscopic organisms that live in the ocean. Zooplankton are tiny animals. Phytoplankton are tiny plants. Some examples of phytoplankton include many types of algae, or single-celled plants.
Photosynthesis, used by plants and some algae.
Multicellular photosynthetic organisms are classified as plants. They are capable of producing their own food through the process of photosynthesis.
Algae, plants, and cyanobacteria.
plants There are other organisms beside plants. Algae,some bacteria and protozoans are examples
In the food chain, organism that are producers are green plants and algae. These organisms make there own nutrients through the process of photosynthesis.
For starters, algae are plants. Plants never use oxygen. Animals use oxygen in the process of respiration. Decomposers use oxygen in the process of respiration when decomposing plants and animals including algae.
