Tinea cruris, most commonly known as jock itch, is a fungal infection of the skin. It belongs to a group of fungal skin infections called tinea. Like other tinea infections, jock itch is caused by mold-like fungi, which are known as dermatophytes.
Ecologists (scientists who study the relationships of organisms with their living and nonliving environment) generally recognize two kinds of succession, primary succession and secondary succession. Primary succession takes place on an area that is originally completely empty of life. As an example, an area that has been covered by a flow of lava has, for a time, no life at all on it. Over a period of time, however, various kinds of organisms begin to grow in the area.
Primary Succession begins from scratch and it forms from desolate land. Primary Succession needs time to pass starting from rocks to lichens and mosses to grasses, etc.Second â¦ ary Succession, on the other hand, is formed from a disaster or human interaction on an ecosystem that was most likely in bad shape.rimary Succession begins from scratch and it forms from desolate land.
