A scientist is examining an organism that feeds on decaying matter to gain energy for survival. What kingdom would be the best option when clarifying this organism?

fungi

Explanation:fungi are heterotrophic plants. They are organisms that lack chlorophyll,true roots,stems and leaves .as a result they cannot produce their own food .they depend on dead and decaying matter for their source of energy, thus they are saprophytes.Fungi may be Unicellular or multicellular. They consist of harlike filaments of hyphae which fuses together and forms a mass of mycellium. Common example of fungi we see around us are mushrooms. Fungi feed by secreting digestive enzymes into their substrate and they absorb the nutrients that are broken down by the enzymes. Fungi are important because they help to rid the environment of dead matter by decomposing them. Matured fungi reproduce asexually by the means of spores
