Answer:
Plants are made up of roots, stems, and leaves, and most produce flowers, fruit, and seeds. ... Using carbon dioxide, water, nutrients, and energy from sunlight, the chlorophyll makes the food that the plant needs. This process is called photosynthesis. During this process, plants release oxygen into the air. During the day, plants soak up sunlight during photosynthesis, the process they use to get energy. But when the sun goes down, plants' opportunity to eat disappears and other physiological processes take over, including energy metabolism and growth. Plants release oxygen during the day in the presence of natural light through the process of photosynthesis. While at night, the plants uptake oxygen and release carbon dioxide, which is called respiration.

Answer:
D variations in individuals are not heritable
Explanation:
Genetic variation in individuals is what drives evolution. In a population of individuals in an environment, with the adequate resources, overpopulation can occur. However, resources are usually a limiting factor for population growth: there is not sufficient food/shelter etc. for everyone to survive.
Some individuals are better suited to success in the environment. This is because of random variation in their DNA that has arisen that give them a selective advantage. This allows them to thrive, take advantage of the limited resources over other members of the population, and be more likely to survive to reproductive age. This is natural selection.
Because this variation is genetic (in the DNA), they can then pass it on to their offspring. Over time, this leads to evolution over time.
