Explanation:

Each organism in a population produces more offspring than can survive. This is called overproduction. In order for natural selection to occur, populations must have variation. When the environment changes, nature selects favorable adaptations. Over time, these build up in a population.

the overall balanced equation

6co2 + 6h2o > c6h12o6 + 6o2

sunlight energy

where: co2 = carbon dioxide

h2o = water

light energy is required

c6h12o6 = glucose

o2 = oxygen

multiplying and dividing the two decimals and the eqations by the same number of the overalls
