True or False: The excess energy from cellular respiration is DIRECTLY used for completing bodily processes.

• True. We need these energy for our cells to go through processes.

• False. This energy must be packaged in another molecule before it can be used.

Food molecules in ecosystems have what in common?

• Atoms like carbon, hydrogen and oxygen.

• Atoms like nitrogen, phosphorus and zinc.

• They all have the same amount of energy.

True or False: All ecosystems start with producers going through photosynthesis to provide food for the food web.

• True. Photosynthesis is the only way to build food molecules at the bottom of the web.

• False. Chemosynthesis can occur without sunlight to build food molecules at the bottom of the web.

What is also an outcome of cellular respiration?

• More atoms are created

• More energy is created

• There is excess energy not used to create the outputs

• There are excess atoms not used to create the outputs

Why do big macromolecules hold more energy? (Things like carbs have more calories)

• They contain more matter, which stores energy

• They contain more bonds, which store energy.

What molecules are the inputs of cellular respiration?

• CO2 and H2O

• O2 and H2O

• O2 and Glucose

• CO2 and O2

What molecules are the outputs of cellular respiration?

• CO2 and H2O

• O2 and H2O

• O2 and Glucose

• CO2 and O2

What molecules are the inputs of photosynthesis?

• CO2 and H2O

• O2 and H2O

• CO2 and Glucose

• CO2 and O2

In a molecule like H20 or O2 the "energy" is the ______.

• bonds

• whole molecule

• atoms

How do we know energy is conserved in cellular respiration?

• The energy in the inputs is equal to the energy in the outputs plus the excess energy that is released. The total stays the same.

• The energy in the inputs is less than the energy in the outputs plus the excess energy that is released.

• The energy in the inputs is more than the energy in the outputs plus the excess energy that is released.

• Energy changes into ATP so it cannot be conserved.
