100

An organism that makes its own food.

What is an autotroph?

100

The process where plants make food from sunlight.

What is photosynthesis?

100

This cycle utilizes the processes of evaporation, precipitation and transpiration.

What is the water cycle?

100

The long-term heating of Earth's surface.

What is Global Warming?

100

The level of the frog in this image.

What is secondary consumer?

200
An organism that breaks down dead organisms for food.

What is a decomposer?

200

The process that organisms use to break down food for energy.

What is respiration?

200

Most of the carbon is stored here in the carbon cycle.

What is the atmosphere?

200

The burning of fossil fuels for energy.

What is combustion?

200

The producers make up this level of the energy pyramid.

What is the (1st, base, primary) level?

300

An organism that eats both plants and animals.

What is an omnivore?

300

The term used to describe the trapping of heat in the atmosphere by gases.

What is the greenhouse effect?

300

Plants and animals release carbon dioxide into the air through this process.

What is respiration?

300

This greenhouse gas is in the highest concentration of all the greenhouse gases.

What is CO2?

300

The level of the hawk in this image.

What is (quaternary consumer/5th level)?

400

Organisms that need to eat to get energy.

What are heterotrophs?

400

The process where nitrogen runoff from fertilizers causes rapid growth of algae in ponds, decreasing the amount of oxygen in the water for other organisms.

What is eutrophication?

400

The net effect of human activity on the carbon cycle.

What is higher CO2 concentration?

400

These types of resources are being used to combat global warming instead of fossil fuels.

What are renewable resources?

400

The ultimate source of energy in an ecosystem.

What is sunlight?

500

The organisms that make up the 1st level of the energy pyramid.

What are producers?

500

The long-term pattern of weather in an area.

What is climate?

500

Without this process, the carbon cycle will completely stop.

What is photosynthesis?

500

This human impact has led to a decrease in biodiversity in rainforests.

What is deforestation?

500

The amount of energy the snake receives from eating a rat when the producers have 759,230 J of energy.

What is 759.23 J?
