Mario and Luigi
Heterotrophs and autotrophs 
Herbivores and carnivores

Answer 1

Question 2

What is primary purpose of photosynthesis?

1) To use light energy to convert inorganic compounds into chemical energy.
2) to use light to take pictures of the surroundings.
3) to transform glucose into ATP energy
4) to convert food to carbon dioxide

Answer 2

1) to use light energy to convert inorganic compounds into chemical energy

Question 3

The basic chemical equation for photosynthesis is…..

1) CO2 +O2>Energy
2) 2H + O> H2O
3) Chlorophyll + CO2 > C6H12O6(glucose)
