Final answer:
Photosynthesis is a result of natural selection and enhances genetic diversity, it is not a random process.
Step-by-step explanation:
b. Photosynthesis is a result of natural selection because it allows organisms that can efficiently use nutrients in their environment to survive and reproduce, while organisms that cannot utilize these nutrients as effectively are less likely to thrive.
a. Photosynthesis enhances genetic diversity because it is a process that allows organisms to convert solar energy into chemical energy, enabling them to build new structures and achieve biodiversity. This diversity is further influenced by natural selection favoring organisms that can extract maximal value from the available nutrients.
c. Photosynthesis is not a random process, as it involves specific biochemical pathways and reactions that are highly regulated and coordinated. The evolution of photosynthesis is a result of natural selection acting on organisms that were able to harness energy from the sun and utilize it for their metabolic needs.
