What is the primary source of energy for most life on Earth?

• Geothermal energy

• Chemical energy stored in water

• Solar energy

• Energy released by decomposers

The main purpose of photosynthesis is to convert:

• Chemical energy into heat energy.

• Heat energy into light energy.

• Light energy into chemical energy

• Kinetic energy into potential energy.

Which molecule is the main carbon-based product created by plants during photosynthesis?

• Oxygen

• Carbon dioxide

• Chlorophyll

• Glucose

The primary molecule in plant cells responsible for capturing light energy is:

Which two molecules are the primary reactants (inputs) required for photosynthesis?

• Oxygen and Glucose

• Glucose and Water

• Carbon Dioxide and Water

• Oxygen and Carbon Dioxide

Organisms that capture solar energy to produce their own food are known as:

• Consumers

• Decomposers

• Producers

• Heterotrophs

The energy stored in the bonds of glucose molecules is classified as:

• Solar energy

• Kinetic energy

• Thermal energy

• Chemical energy

Which essential product of photosynthesis is released into the atmosphere?

• Nitrogen

• Oxygen

• Carbon Dioxide

• Methane

If plants could no longer perform photosynthesis, the immediate effect on consumers would be:

• An increase in atmospheric CO2

• A loss of the primary source of organic molecules

• Increased access to water

• A decrease in atmospheric oxygen

The process of converting light energy into the chemical energy stored in glucose occurs within which organelle?

• Nucleus

• Chloroplast

• Mitochondria

• Cell Membrane
