Population Changes
Change is inevitable in nature.
Ecosystems have to cope with sudden changes like hurricanes and long term changes like ice ages.
Healthy Ecosystems will withstand the stress caused by change. Populations will recover or adapt to a new climate.
Population Changes
Stressed ecosystems do not handle change well.
They are already fragile or out of balance. They react with population spikes (boom) and population crashes (bust)
Population spike (boom)- Increase in population happens quickly.
Population crash (bust)- Decrease in population happens quickly
Sometimes a stressed ecosystem will not recover from change.
Population Effects Ecosystems
If a change affects one population in an ecosystem, the change will be felt throughout the system over time.
When one population of organisms increases or decreases, other populations will be affected because all living things are interrelated.

Answer:
The gas argon does not reach a state of vibrational excitation when infrared radiation strikes this gas.
Explanation:
The dry atmosphere is composed almost entirely of nitrogen (in a volumetric mixing ratio of 78.1%) and oxygen (20.9%), plus a series of oligogases such as argon (0.93%), helium and gases of greenhouse effect such as carbon dioxide (0.035%) and ozone. In addition, the atmosphere contains water vapor in very variable amounts (about 1%) and aerosols.
Greenhouse gases or greenhouse gases are the gaseous components of the atmosphere, both natural and anthropogenic, that absorb and emit radiation at certain wavelengths of the infrared radiation spectrum emitted by the Earth's surface, the atmosphere and clouds . In the Earth's atmosphere, the main greenhouse gases (GHG) are water vapor (H2O), carbon dioxide (CO2), nitrous oxide (N2O), methane (CH4) and ozone (O3 ). There is also in the atmosphere a series of greenhouse gases (GHG) created entirely by humans, such as halocarbons (compounds containing chlorine, bromine or fluorine and carbon, these compounds can act as potent greenhouse gases in the atmosphere and they are also one of the causes of the depletion of the ozone layer in the atmosphere) regulated by the Montreal Protocol. In addition to CO2, N2O and CH4, the Kyoto Protocol sets standards regarding sulfur hexafluoride (SF6), hydrofluorocarbons (HFCs) and perfluorocarbons (PFCs).
The difference between argon and greenhouse gases such as CO2 is that the individual atoms in the argon do not have free bonds and therefore do not vibrate. As a consequence, it does not reach a state of vibrational excitation when infrared radiation strikes this gas.
