In a pond there are dragonflies, frogs, lily pads, and cattails. We are going to study the dissolved oxygen levels and mud levels in the water and how they affect the living organisms. At what level of organization will we be working?

Is this a description of the areas' weather or climate?
Climate
What is the process by which certain gases trap heat that would otherwise escape the Earth and radiate into space?

What makes the phosphorous cycle unique?
Phosphorous is never in the atmosphere.
Hydrosphere and Atmosphere
Choose the correct options:
Hot air (risies or sinks) and causes (high or low) pressure systems and (produces or prevents) rainfall.
Hot air RISES and causes LOW pressure systems and PRODUCES rainfall.
Why is there greater biomass at the bottom of a pyramid of biomass?
There is less and less energy available to support life as you move up the energy pyramid, therefore there is less and less biomass at each level.
What is the difference between producers and consumers?
Producers are autographs - get energy from the sun
Consumers - depend on autotrophs or other consumers for energy
