Answer:
Carbon Dioxide and Water
Explanation:
During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.
Causes death of aquatic organisms due to unavailability of air in water, chemicals block air circulation in water bodies
Answer:
Sexual reproduction enhances the genetic variation within the population, as new individuals are produced due to the random combination of genetic substances obtained from two parents. As only fit individuals attain sexual maturity and breed, the entire population seems to incline towards enhancing fitness in its environment. However, there is always a probability that the random combination producing the genome of the offspring will in real sense generate an offspring that is less fit for the environment in comparison to its parents.
