Photosynthesis
Photosynthesis and cellular respiration are opposite processes. One difference between the two is that photosynthesis produces oxygen, and cellular respiration produces carbon dioxide.
TRUE or FALSE
True
False
If you put a green leaf in a cup of water, would bubbles come out of it because photosynthesis is releasing oxygen?
True
False

Removes
Plants collect carbon dioxide through small pores in their leaves called...
Glucose
Carbon
Oxygen
Stomata
Sunlight is essential for photosynthesis, because...
Provides energy
Makes ATP energy
Helps plants grow
During photosynthesis, the _________ helps the plants absorb and use energy from the sun, so that chloroplasts can aid in photosynthesis.
Chlorophyll
Glucose
ATP Energy
Water
Energy storage molecules are made by...
Secondary Consumers
Decomposers
Producers
Consumers
If the producers didn't make enough energy storage molecules the the ecosystem would...
Grow stronger
Die
Make plants stop growing but animals getting more food
Decomposers would turn the dead matter into more carbon dioxide and keep the ecosystem going.

originally comes from earth
originally comes from energy
originally comes from the sun
originally comes from light
water, salt, air and soil are examples of
the periodic table
energy factors
biotic factors
abiotic factors
Abiotic factors are parts of the ecosystem that are
not living
living
