What do algae form symbiotic relationships with?

Algae can form symbiotic relationships with a variety of organisms, including fungi, animals, and plants. Some common examples of symbiotic relationships involving algae include:

1. Lichens: Algae can form a symbiotic relationship with fungi to create lichens. The algae provide the fungi with photosynthetic energy, while the fungi provide structural support and protection for the algae.

2. Coral: Algae known as zooxanthellae form a symbiotic relationship with coral polyps. The algae provide the coral with nutrients through photosynthesis, while the coral provides the algae with a protected environment to grow.

3. Salamanders: Certain species of algae can form symbiotic relationships with aquatic salamanders, providing them with camouflage and potentially some nutritional benefits.

4. Plants: Algae can form symbiotic relationships with certain plants, such as ferns and cycads, to provide them with nutrients and help them thrive in certain environments.

Overall, algae can form symbiotic relationships with a wide range of organisms, benefiting both parties in various ways.
