True or false:
An example of interdependence is between plants and humans. Plants provide oxygen to humans so that we can survive, and humans provide carbon dioxide to plants so that they can make their own food.

Energy from the sun, or solar energy, travels through space to be absorbed by consumers in order for them to create food.
False
Energy from the sun, or solar energy, travels through space to be absorbed by producers in order for them to create food.

Where is the majority of freshwater found and why is it unusable?
Most of Earth's freshwater is found in glaciers and ice caps. The freshwater there is unusable because it is frozen and inaccessible.

Zebra mussels, which are not native to Lake Michigan, compete with the native mussels for food, space, and oxygen, and are reproducing twice as fast as the native mussels. What would you call the Zebra mussels? What do you think will happen to the ecosystem in Lake Michigan as a result?
The Zebra mussels are invasive species. Because the zebra mussels reproduce twice as fast, it would cause an overpopulation of the zebra mussels. The ecosystem will become unbalanced and eventually the native mussels will die out.

How does the energy we get from food relate to the Sun? Give an example of one food that we eat.
The Sun is the energy source for all energy in a food web. For example, we eat salads. The lettuce in the salad we eat is a producer and makes its own food using the energy from the Sun. Without the Sun, we would not have the food we eat.

What is an El Niño and what does it do to the weather in California?
The El Niño is when warm wind from the equator causes the ocean water to be warmer than usual.
California would get more precipitation, meaning heavier rain and snow.

What is desalination and why is it necessary?
Desalination is the process of removing salt and other minerals from ocean water to make it fresh and clean to drink. Humans need to drink freshwater to survive, but there is a limited amount available to us. If we can make ocean water not salty, it would be drinkable.

What is deep lake cooling and how does it work?
Deep lake cooling is an alternative energy source to fossil fuel powered electricity. The system takes cold water from the lake, uses that cold water to cool down some air, and then pumps the cold air into the building. The water is then pumped back to the lake.
