Answer:
Multicellular
Eukaryotic
Heterotrophs
Explanation:
Both cells of fungi and animals are eukaryotic meaning they have nucleus and organelles. They are multicellular organisms (meaning they are composed of many cells). Their cells are also heterotrophic meaning they depend on organic molecules for energy as opposed to plants that can make their food from abiotic factors. Fungi, however, digest their molecules extracellularly while animals do it intracellularly.
