The graph shows the results of an investigation into the effect of distance from a light source on the rate of photosynthesis. Based on the data represented in the graph, the rate of photosynthesis_1_ as the level of available _2_ increases. The greatest change in the rate of photosynthesis occurs when the light level is _3_. Which table contains the numbers and terms that correctly complete the statements?

A:

Explanation:

Photosynthesis is a chemical process in plants and other primary producers that is integral to energy production. Carbohydrates containing energy is made from light, water and carbon dioxide in the form of glucose molecules.

As a result, the waste product oxygen is released. Photosynthesis is a rate-limited reaction, depending on many factors, including the concentration of carbon dioxide, atmospheric temperature and intensity of light. Because the energy needed is derived from photons, i.e. light particles, lower light intensities lower the rate of photosynthesis significantly.

genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).
