Example 1: Humans require oxygen for life, and plants use carbon dioxide for photosynthesis. Here, both humans and plants benefit mutually. Humans use the oxygen given by the plants. In return, plants use carbon dioxide, which Humans exhale.
Example 2: Lichen is a mutualistic relationship between a fungus and algae. Algae provide food to fungi obtained from photosynthesis. The fungus provides anchoring and protection to the algae.
