The correct answer is: D. heterotrophic eukaryotes
Fungi are eukaryotic organisms that are heterotrophic, meaning they cannot produce their own food and must consume organic matter to survive. They are also non-photosynthetic, meaning they do not use sunlight to produce food. Fungi are found in a variety of habitats, including soil, water, and on decaying organic matter. They play an important role in the environment by decomposing dead organisms and recycling nutrients.
A. Single-celled prokaryotes are organisms that do not have a nucleus or other membrane-bound organelles. They are the simplest type of organism and include bacteria and archaea.
B. Phototrophic eukaryotes are organisms that use sunlight to produce food. They include plants, algae, and some protists.
C. Eukaryotes single-celled and primitive multi-celled organisms is not a correct option.
