the science calorie (little c) is a measure of heat energy the food calorie (big C) is a measure of energy that we burn, but it is equal to 1,000 science calories so 1 big C is equal to 1,000 little c's.
Protists are a group made up of protozoa, unicellular algae, and slime molds. We will concentrate on the animal portion of this group: the protozoa (proto = first, zoa = animals).
Unicellular organisms. A unicellular organism is a living thing that is just one cell. There are different types of unicellular organism, including: 1  bacteria. 2  protozoa.3  unicellular fungi.rotozoa are unicellular organisms that live in water or in damp places. The amoeba is an example of one. Although it is just one cell, it has adaptations that let it behave a bit like an animal: 1  it produces pseudopodia (âfalse feetâ) that let it move about. 2  its pseudopodia can surround food and take it inside the cell.
