Question

Digrams of balance in an ecosystem an eqilibrium

Answer 1

Imagine walking across a balance beam. You keep your arms out and sway from side to side as you walk across the beam. As long as you keep your weight in the center you stay balanced and stay on the beam. But if you become out of balance you fall off. Being in balance is important for many aspects of living things, not just playing on the playground.
All living things must remain in balance, or equilibrium, also known as homeostasis. Our bodies maintain a balance of many things such as temperature. If we are too hot we sweat and if we are too cold we shiver. Our temperature must remain in equilibrium.
Even larger collections of living things like ecosystems must be in balance too. An ecosystem is a collection of living and non-living things in an area. There are lots of types of ecosystems we already know, such as a forest or a meadow. Any collection of living and non-living things in an area is an ecosystem, even a small ecosystem like your backyard.
