Algae are found in a variety of habitats including aquatic, terrestrial, and unusual environments. They are divided into three main types based on habitat - terrestrial algae that live on moist soil and surfaces, aquatic algae that live in water, and algae found in unusual habitats. Terrestrial algae, also called edaphophytes, live on or inside earth and occur on moist soil, tree bark, damp wood, rocks, and cliffs.

1. Algae in Diversified Habitats

2. • Algae are chlorophyll-bearing autotrophic members of thallophytes
comprising a large heterogeneous assemblage of relatively simple
plants.
• Algae may be aquatic, semi-aquatic, or terrestrial in their habitat.
• In the sea, they make up the major part of the vegetation.
• On pools of calm water, they often form the green-colored “pond
screen” or “pond scum“.

3. Types of algal habitat
• Algae are found everywhere on the earth, in air, water, and soil.
• Three types of algae can be found based on their habitat.
• Terrestrial algae,
• Aquatic algae
• Algae as unusual habitats

4. Terrestrial algae
• Terrestrial algae are also known as edaphophytes.
• The edaphophytes are found upon or inside of the earth.
• They occur on moist soil as a part of soil flora, and also on barks of
trees, on damp wood, on rocks and cliffs, etc.
• They are two types- Saphophytes and Cryptophytes.
