Fungi

Fungi can be single-celled or complex multicellular creatures. They are found in pretty much any natural surroundings; however, they generally live on the land, principally in soil or plant material instead of in the ocean or water. Fungi are the members of the group called the decomposers that live off dead and decaying matters. Fungi assume a significant part in the carbon cycle and its different components. They act as a parasite by causing illnesses like rusts, scabs, or ulcers. In crops, contagious illnesses can prompt critical money-related misfortune for the rancher. An exceptionally modest number of growths cause illnesses in creatures. In people, these incorporate skin illnesses such as competitors' feet, ringworm, and thrush.
