Unlike animal-like protists, many fungus-like protists are a) decomposers b) parasites c) heterotrophic d) unicellular

a) decomposers i think im not 100% sure.

A. decomposers

The decomposers are organisms that break down the dead and decaying organisms such as plants and animals. The fungi are the primary decomposers if the litter in the ecosystem. The fungi are saprophytic organisms which feed upon the nutrients obtained after the decomposition process. They exhibit a fungal hyphae which can penetrate deep inside of soil in order to obtain the food. Protists are simple unicellular organisms, these are members of the kingdom Protista. Some of these Protists shows similarity in structure and function with animals, plants, fungi and microbes. The molds are protists which are found on feeding upon dead decaying matter like fungi. Examples are slime mold and water molds.

meiosis is the first to occur after the nuclei of opposite of opposite mating types fuse

unicellular organisms, like bacteria, are able to perform all life functions within one single cell. multicellular organisms need many different types of cells to carry out the same life processes. each of these special types of cells has a different structure that it perform a specific function.
