photosynthesis by algae living in coral tissue. Human body is combination of trillions of cells and a singular cell of smaller organelles (mitochondria) and others, all living symbiotically. Chloroplasts in green leaves, apparatus for photosynthesis are complete smaller organisms like cells and mitochondria, capable for self replication. Then there is purple bacteria, the photosynthetic bacteria that employs its extremely sensitive molecular antenna system that absorbs individual photons and passes on to reaction centre the green chloroplasts where splitting of water molecules and synthesis of various products. proteins, carbohydrates etc. takes place. Large number of green algae grow in tissues of the worm (Convoluta roncoffensis), releasing nitrogen and preparing nitrogen compounds for host and in return get suitable matrix for its growth. Sea anemome (Adamsia palliata) grows on shell of the hermit crab (Eupagurs pridaux) and serve as powerful deterrent against predacious fish, A worm Neresis also lives inside the shell and helps to keep it clean and in return gets food. The crocodile bird fearlessly enters the mouth of crocodile, removes leeches around teeth, the ferocious crocodile does not harm it. A long tube worm of genus Riftia possesses no mouth, stomach, intestines or annus and the bacteria living in its inner nutritional tissue provide it the primitive circulatory systems. Nitrogen fixing bacteria in roots of leguminous plants fix nitrogen directly and make it available to plant. Likewise Mycorrhiza fungus make nutrients from soil available to plants. Green algae grows on long groove hair of sloth bear making it turn almost green and help in camouflaging. In crab-coelentrate relationship the later helps to camouflage and in return gets food. Mixed groups of zebras and ostriches derive mutual benefit by virtue of keen sight of ostriches and greater power of scent of zebras.
There is an intricate symbiotic relationship between the tree Colvillea major and the Dodo bird. The seeds of this tree would germinate only after passing through the gut of
