Water Cycle
This process changes liquid water into water vapor.
Evaporation
Plants take in this gas during photosynthesis.
Carbon dioxide
Burning coal, oil, and natural gas adds more of this gas to the atmosphere
Carbon dioxide
Sunlight is this type of growth factor: genetic or environmental
Environmental
This pH value is neutral
pH 7
This process changes water vapor into tiny liquid droplets
Condensation
Plants release this gas during photosynthesis
Oxygen
Carbon dioxide belongs to this group of gases that trap heat in the atmosphere
A plant variety inherited from its parent is this type of growth.
Classify a substance with pH 3
acid
Name the two main forces that drive the water cycle
Solar energy (sun) and gravity
This process releases usable energy from food in cells
Cellular respiration
This word means the variety of living things in an ecosystem
Biodiversity
Name two environmental factors that can affect an organism's growth
answers vary
Indicator
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.
Give one ecosystem service that healthy ecosystems provide to people
-clean water
-clean air
-food
-more
True or false
Genes alone determine exactly how large an organism will grow.
False
A solution changes from pH 3 to pH 6 after a base is added. Did it move toward or away from neutral?
Toward neutral
After rain falls, some water flows across the ground while some enters the soil. Name both processes.
Runoff and infiltration
These organisms return nutrients to the soil and air by breaking down dead matter
Decomposers
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
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
An acid and a base are mixed and the final pH is 7. Name the reaction.
Neutralization
