If the number of photosynthetic organisms on Earth decreased drastically, which would happen as a result? Less water would be av
ailable on Earth’s surface. Less solar energy would reach Earth’s atmosphere. More oxygen gas would be found in Earth’s atmosphere. More carbon dioxide gas would be found in Earth’s atmosphere.
More Carbon Dioxide Gas would be found in the atmosphere because there would not be enough plants to photosynthesize the Carbon Dioxide that living creatures create.
The amount of CO2 found in the atmosphere varies over the course of a year. Much of this variation happens because of the role of plants in the carbon cycle. Respiration happens all the time, but dominates during the colder months of the year, resulting in higher CO2 levels in the atmosphere during those months.
