Which of these statements is true about autotrophs, but not heterotrophs?

They use sugar and oxygen to make carbon dioxide and water.

They use chlorophyll and oxygen to make carbon dioxide and water.

They use sunlight, water, and carbon dioxide to make sugars.

They use sunlight, water, and oxygen to make chlorophyll.

How are the reactants represented in the chemical equation for photosynthesis?

6CO2 + O2

6CO2 + 6H2O

C6H12O6 + 6O2

C6H12O6 + 6H2O

Which statement best describes the relationship of photosynthesis and energy?

The process of photosynthesis is energy-storing because the process converts light energy into chemical energy, which is stored in the bonds of glucose.

The process of photosynthesis is energy-releasing because the process converts light energy into free energy that can be used for cell functions.

The process of photosynthesis is energy-conserving because no energy is used throughout the process of forming glucose and oxygen molecules.

The process of photosynthesis is energy-wasting because photosynthesis is an inefficient process that depletes the cell of energy stored in the bonds of glucose.

How are the products represented in the chemical equation for photosynthesis?

O2 + 6CO2

C6H12O6 + 6H2O

6CO2 + 6H2O

C6H12O6 + 6O2

In which situation would it be least likely for a scientist to revise her experimental methods?

if her results support her hypothesis

if her data do not support her hypothesis

if no conclusions can be drawn from the data

if results are the same after repeating the procedure

Miles wants to write the equation for photosynthesis. The diagram below represents one of the molecules in the equation.Which chemical formula reflects the diagram?

Johannes wants to know whether soil, water, or both are needed for plant growth. He chooses to conduct experiments on a willow tree for five years to answer his question. How can his experimental methods be changed to improve his experiment?

He needs to ask scientists what they think.

He needs to conduct the experiment for a longer period.

He needs to use a larger sample size.

He needs to test more factors in the environment.

Which statement summarizes a change that occurs during photosynthesis?

It converts visible light to high-energy gamma rays.

It converts carbon to oxygen.

It converts light energy to chemical energy.

It converts energy to mass.
