Factors Affecting Population Growth 69Notes D. The logistic growth equation is a mathematical representation of Malthus'idea of population growth and environmental resistance.E. Concept of Chapman (1931)1.
The Earth's oceans contain a large amount of CO2 in the form of bicarbonate and carbonate ions â much more than the amount in the atmosphere. The bicarbonate is produced in reactions between rock, water, and carbon dioxide.
Carbon-14. An important difference between CO2 from natural sources and CO2 from fossil fuels is the age of the carbon it contains. Younger natural sources of CO2 are relatively rich in carbon-14. But since carbon-14 has a half-life of about 5,700 years, it canât be found in fossil fuels that are millions of years old. large diversity of gasses in the atmosphere influence air quality, climate change and the recovery of the ozone layer. Measuring the concentrations of these gases in the atmosphere is quite straightforward. But pinpointing wether the gasses are a natural occurrence or anthropogenic in nature is a lot more complicated.
