What do living things use ATP for?

• Cellular rest

• Cellular energy

• Cellular degradation

• Cellular death

What happens to other 90% of energy if only 10% gets passed to the next trophic level?

• false, 100% gets transferred to the next level

• the predator scares 90% out of the prey

• the predator uses the energy to fight off bacteria

• most get lost to heat

Why do plants take CO2 out of the air?

• to use the carbon for sugars

• to use the carbon for production of water

• to use the carbon to make oxygen

Why does a plant eventually stop producing the products of photosynthesis if placed in a dark room long enough?

• The Calvin Cycle only works in the light

• The Calvin Cycle runs out of carbon dioxide

• The Calvin Cycle needs the products of the light dependent reactions

What happens when water gets split by photosystem II?

• Electrons are donated to the ETC and oxygen gas is made a waste product

• Carbon dioxide is produced allowing the start of The Calvin Cycle

• Oxygen gas combines with carbon dioxide to make NADPH

What stage uses carbon dioxide in photosynthesis?

• ETC

• Calvin Cycle

• Light dependent reactions

What are the reactants of photosynthesis?
