The following data were collected on two species of plants from the same genus:
plant 1

percent water composition = 90%

photosynthetic mechanism = c4

plant 2

percent water composition = 32%

photosynthetic mechanism = c3

based on this information, which statement is likely true?
a. both plants inhabit the same environment.
b. plant 1 has evolved mechanisms for storing large quantities of water.
c. plant 2 has evolved mechanisms for storing carbon dioxide.
d. the plants are competing for the same ecological niche.
