History studies the past of people. In order to date the events that ocurred in the past, historians use units of time. In history, we use mainly years and centuries as units of time.
An ecosystem consists of all the organisms living in one place, as well as the physical environment they live in. Organisms in an ecosystem interrelate with each other. For example, a dessert is an ecosystem that consists of all the living things that live there (camels, lizards, snakes, cactuses,...), the physical environment (sand, rocks and air), and the interrelationships among the living things and the environment.
Ecosystems come in all shapes and sizes. They can be as small as a terrarium in your room or as big as an ocean.
ECOSYSTEM = PHYSICAL ENVIROMENT + LIVING THINGS (fauna and flora)
