4 Major Spheres
Refers to all living this on Earth
Biosphere
Refers to the continuous movement of water between the Earth's surface and the air.
Water cycle
What are the different roles of organisms in the ecosytem?
Producers, consumers and decomposers
This models the series of feeding relationships among organisms in the ecosytem.
All water on Earth is recycled through this process.
The water cycle.
This includes water in all its forms
Hydrosphere
This is the process by which water vapor turns into clouds.
Condensation
They break down dead and / or decaying matter.
Decomposers
Overlapping food chains in the ecosystem
Food web
Is a thick sheet of slow-moving ice
Glacier
Refers to all landforms, including those underneath the Earth's visible surface
Geosphere
Runoff
What are the 3 types of consumers?
Herbivore, carnivore, omnivore
What is the source of all the energy in a food chain?
The Sun
Any harmful substance that affects Earth's resources
Pollution
Is the layer of gases surrounding the Earth.
Atmosphere
Plants and animals are the integral parts of this cycle, because of the direct exchange of these elements.
Oxygen-Carbon Cycle
Organisms that use the energy from the sun to make their own food.
Producers
Where does food chain start and where does it end?
It starts with producers and ends with decomposers
The practice of using resources wisely.
Conservation
It makes up most of the Earth's surface
Hydrosphere
The continuous circulation of nitrogen from the air to the soil to organism and back.
Nitrogen Cycle
Organisms that can not make their own food.
Consumers
The movement of energy from one organism to another in a food chain or food web
Energy Flow
A kind of precipitation that contains gases and harmful chemicals that form acids.
Acid rain
