The fungus in return gets organic materials from the alga. The alga provides organic nutrients for the lichen through photosynthesis and the lichen provides protection from drying out because the alga lives within the fungus's cell wall.
similarities:

4. Vertebrates and invertebrates belong to kingdom Animal.
Difference:
Invertebrates are those that do not possess a vertebral column or backbone while Vertebrates are those where vertebral column or backbone is present.

Using the fossil remains of plants and animal species a boundary between the Permian and Triassic was identified because the fossils indicated that there was elimination of more species of plants and animals.
