Explanation: mushrooms are fungi.fungi are heterotrophic organisms which do not have chlorophyll,true roots or leaves.they feed on decaying matter,as a result.a mushroom usually has a threadlike filaments called hyphae.a mass of hyphae forms the mycellium .fungi reproduce asexually by means of spores. A fungi mycellium can grow from a single spore.the spore are motile and they germinate when they land on an suitable surface.mushrooms usually grow on soil and trees.most mushrooms we see around us are basidiomycetes.they produce basidiospores borne in the basidium.
Natural selection allows nature to chose which species survives. Only the fittest get to pass on their genes. And by fittest i mean the ones that are better adapted to the environment.<span />
