What is Energy?

100

These organisms eat plants. Also known as herbivores.

What are primary consumers?

100

An organsim that must consume other organsims for energy.

What are heterotrophs?

100

The largest populations in an energy pyramid.

What are the producers?

200

Cells use this molecule for energy.

What is ATP?

200

These organisms will eat primary consumers. Also known as carnivores or omnivores.

What are secondary consumers?

200

Typically smaller organisms that absorb nutrients from dead decaying matter.

What are decomposers?

200

The smallest population in the energy pyramid.

What are top predators/tertiary consumers?

300

This is the word used for energy in ecology.

What is trophic?

300

These are organisms that produce their own food through light energy.

What are producers?

300

Organism that uses the Sun to gain food.

What is an autotroph?

300

In a food chain or web, the arrow points to this.

What is the consumer?

300

Energy can’t be transferred with 100% efficiency, some will be lost in the process.

What is Law #2?

400

Food energy is measured in this.

What is kcals or kilocalories?

400

These organisms will eat secondary consumers. Also known as carnivores or omnivores.

What are tertiary consumers?

400

Typically larger organisms that consume dead or decaying organic matter.

What are detritivores?

400

The amount of energy transfered between trophic levels.

What is 10%?

400

Energy and matter cannot be created or destroyed, only converted.

What is Law #1

500

Energy for abiotic factors is measured in this.

What is joules?
