This process changes liquid water into water vapor.

Evaporation

100

Plants take in this gas during photosynthesis.

Carbon dioxide 

100

Burning coal, oil, and natural gas adds more of this gas to the atmosphere

Carbon dioxide 

100

Sunlight is this type of growth factor: genetic or environmental

Environmental

100

This pH value is neutral

pH 7

200

This process changes water vapor into tiny liquid droplets 

Condensation

200

Plants release this gas during photosynthesis

Oxygen

200

Carbon dioxide belongs to this group of gases that trap heat in the atmosphere

Greenhouse gases

Classify a substance with pH 3

acid

300

Name the two main forces that drive the water cycle

Solar energy (sun) and gravity

300

This process releases usable energy from food in cells

Cellular respiration 

300

This word means the variety of living things in an ecosystem

Biodiversity

300

Name two environmental factors that can affect an organism's growth

answers vary

300
This substance changes color to help identify an acid or a base. 

Indicator 

400

Put these events in order: precipitation, evaporation, condensation, collection, runoff

evaporation, condensation, precipitation, collection, runoff

Double Points!!!

Explain one way photosynthesis and cellular respiration are connected.

Photosynthesis and cellular respiration uses carbon dioxide and oxygen which connects the carbon and oxygen cycles.

400

Give one ecosystem service that healthy ecosystems provide to people

-clean water

-clean air

-food

-more

400

True or false

Genes alone determine exactly how large an organism will grow.

False 

400

A solution changes from pH 3 to pH 6 after a base is added. Did it move toward or away from neutral?

Toward neutral

500

After rain falls, some water flows across the ground while some enters the soil. Name both processes.

Runoff and infiltration

500

These organisms return nutrients to the soil and air by breaking down dead matter

Decomposers

500

Explain how cutting down a forest can disrupt the carbon cycle

Fewer tress remove carbon dioxide by photosynthesis and stored carbon may be released which increases atmospheric carbon dioxide 

500

Double points 

Two identical bean plants receive equal water and soil. Plant A get 8 hours of light and grows 14 cm; Plant B gets 2 hours and grows 5 cm. Identify the growth factor and explain.

Growth factor - environmental 

Explanation - amount of sunlight 

500

An acid and a base are mixed and the final pH is 7. Name the reaction.

Neutralization
