Biology Basics (Wild Card)
100

This element is the backbone of all organic molecules.

What is carbon?

100

This molecule is the main energy currency of the cell.

What is ATP?

100

Matter in ecosystems is recycled, but this is not.

What is energy?

100

The main source of energy for almost all life on Earth.

What is the Sun?

100

This process uses sunlight to make glucose.

What is photosynthesis?

200

Carbon can form four bonds because it has this many valence electrons.

What is four?

200

Cellular respiration mainly takes place in this organelle.

What is the mitochondrion?

200

Plants get carbon for photosynthesis from this gas in the atmosphere.

What is carbon dioxide?

200

Organisms that make their own food are called these.

What are producers?

200

Plants store extra glucose as this molecule.

What is starch?

300

Glucose, starch, and cellulose belong to this type of macromolecule.

What are carbohydrates?

300

This process breaks down glucose to release energy.

What is cellular respiration?

300

This cycle moves water through evaporation, condensation, and precipitation.

What is the water cycle?

300

Only about this percentage of energy moves from one trophic level to the next.

What is 10%?

300

Animals get energy by doing this to food.

What is eating / consuming / cellular respiration?

400

This type of bond forms when atoms share electrons, common in organic molecules.

What is a covalent bond?

400

This makes its own food (plant)

What is an autotroph?

400

Decomposers are important because they do this to dead organisms.

What is recycle nutrients / break down matter?

400

A diagram that shows energy transfer between organisms is called this.

What is a food chain or food web?

400

This macromolecule includes enzymes and is important for cell structure.

What are proteins?

500
What element would carbohydrates need to add to be able to form amino acids?

What is Nitrogen?

Nitrogen is the primary element missing in carbohydrates that is required for amino acid synthesis. 

500

This stage of cellular respiration happens in the cytoplasm and does not need oxygen.

What is glycolysis?

500

This cycle involves nitrogen fixation, nitrification, and denitrification.  

What is the nitrogen cycle?

500

Energy decreases at higher trophic levels mostly because it is lost as this.

What is heat?

500

This term describes how energy moves in one direction through an ecosystem.

What is energy flow?
