Answer 1

Answer and Explanation:

1. Nutrition- microorganisms are able to feed on food materials obtained from the living or dead bodies of plants or other animals. They are therefore heterotrophs.
2. Movement- both localized and generalized movements which results in the animal moving from one point to another. e.g., using flagella, cilia
3. Excretion- they lack highly specialized excretory organs but some microorganisms use contractile vacuoles for excretion which removes waste.
