100

This element occurs in gas form and is the most abundant in the atmosphere. 

What is Nitrogen? 
100

This member of the food chain refers to organisms that snack on primary consumers. 

What is secondary consumer? 

100

This reserve is well-known for housing significant amounts of phosphorus. 

What is rocks? 

100

This is a process in which dead organisms are broken down, re-introducing important elements into the soil. 

What is Decomposition?

100
This refers to all life on earth.
What is Biosphere? 
200

This element can be found trapped in rocks with other minerals. 

What is Phosphorus? 

200

Other than the food chain, name one of the two other types of food cycle diagrams. 

What is Food Web OR Food Pyramid. 

200

This very large reserve is known for housing an abundance of gases. 

What is the atmosphere? 

200

This process is when plants convert carbon dioxide and water into sugar for chemical energy. 

What is Photosynthesis? 

200

This refers to the layer of gases that surrounds the globe. 

What is the atmosphere? 

300

This element is easily the most abundant in the human body.

What is Oxygen? 

300
This member of the food chain breaks down decomposing organisms and re-introduces elements into the environment as waste. 

What is Decomposers? 

300

This large reserve makes up over 70% of Earth's Surface housing many elements for the nutrient cycle. 

What is the Ocean? 

300
This process is when animals eat other living organisms for chemical energy. 

What is Consumption? 

300

This refers to all bodies of water on Earth including the ocean. 

What is hydrosphere? 
400

This element is the foundational building block of all living things? 

What is Carbon? 

400

This member of the food chain takes up nutrients from it's environment to produce it's own food for chemical energy. 

What is Producers. 

400

This reserve stores Carbon in the form of a sugar called glucose. 

What is plants? 

400

This process is when lightning splits nitrogen gas in the atmosphere, it becomes oxidized, and rain water carries it to the lithosphere. 

What is (lightning) fixation. 

400

This refers to the layer of Earth just beneath the surface. 

What is Lithosphere? 

500

These two elements come together to form a compound called Nitric Oxide. 

What is Nitrogen and Oxygen? 

500

This member of a food chain feasts on everything else. 

What is Apex Consumer/Apex Predator? 

500

This reserve is one of the spheres of the Earth and houses fossil fuels which are utilized for non-renewable energy. 

What is the lithosphere? 

500

This process refers to how atmospheric gases, such as COand N2, move in-and-out of bodies of water from the atmosphere. 

What is Diffusion? 

500

This refers to all frozen water that spans the Earth's surface. 

What is Cryosphere?
