Explanation:
I took the same test and got it right
These mushrooms and other fungi will be classified as decomposers and they will obtain their nutrition by breaking down the body of organisms that have died. These organisms play a vital role in the cycling of nutrients in a food chain, since they convert the macromolecules present in dead organisms into smaller ones and release them back into the environment.
This is Mitosis, which occurs with all nucleated somatic (body) cells, but not in germ (sex) cells.
Germ cells, aka gametes, on the other hand, undergo Meiosis, a process of nuclear cell division whereby 1 parent cell gives rise to 4 daughter cells. These daughter gametes, either sperm or egg cells, all have 1/2 the number of chromosomes as the original parent, termed "haploid." The genes of these gametes were also randomly assorted and crossed-over, allowing a shuffling of their chromosomes' genes.
