2) Ecosystem: A system of biotic and abiotic things that interact with each other in an environment


1) Flagella: Whip-like structures that help the cell move.

2. Fat : fats are also nutrients that provides energy and helps the body digest the certain vitamins but can be also unhealthy if one eats too much.
