ecosystem
What will happen to a population when there are a lot of resources?

What will happen to a population when it grows extremely large?
Resources become more scarce due to competition, causing the population to decrease
What happens when you add cold water to hot water?
They chase each other, creating convection currents.
How do things become cold?
Transfer the thermal energy somewhere else
What causes planets, moons, stars, and other celestial bodies to stay in orbit?
Gravity
relationship when two or more different species benefit from interacting with each other
symbiosis
How can humans effectively save a species?
Increase their resources and protect them against predators or illegal hunting
What causes wind, hurricanes, and tornadoes?
