9. Which process usually uses carbon dioxide molecules?
A) cellular respiration
B) asexual reproduction
C) active transport
D) autotrophic nutrition

D) autotrophic nutrition

Explanation: Autotrophic nutrition is a type of nutrition in which a living organism manufacture its own food. For example, plants are autotrophs and they manufacture their own food using chlorophyll present in plant leaves to trap sunlight in the presence of carbon dioxide and water. This process is known as photosynthesis. In photosynthesis, plants use chlorophyll (a green pigment found in the Chloroplast of plant cells) to trap energy from the sun, in the presence of water and carbon dioxide to produce glucose and oxygen. The balanced chemical equation for photosynthesis is 6CO2 + 6H2O + solar energy --> C6H12O6 + 6O2.

start by finding the main effect, is it bad or good? Than specify if the ph is a representative of bad or good effects from it, once you have solved that then add together the 2 to find what the specific affect is and form your thesis.
