Animal

Animals are eukaryotic organisms with many cells. They do not use light to get energy as plants do through photosynthesis. The study of animals is called zoology. Animals use different ways to get energy from other living things. They usually eat other living things, but some are parasites or have photosynthetic protists as symbionts.

Plants are also multicellular eukaryotic organisms, but most animals are mobile, meaning they can move around. Animals take in oxygen, and give out carbon dioxide. This cellular respiration is part of their metabolism (chemical working). In both these ways they are different from plants. Also, the cells of animals have different cell membranes to other eukaryotes like plants and fungi.
