Answer:
Population dynamics can be described as the size of a particular population and the environmental and biological factors which influence it.
For human populations, a population which is greater than the resources can be controlled by decreasing the number of births in that population. It can be controlled by people migrating from the place due to less resources available.
For animals, the population can be controlled by increasing the amount of predators for the particular population so that they decline in number. Or shifting of the organisms can be done to places where there are enough resources available.
At the conclusion of investigation number 1, the relationship between the light intensity and disks floating is; as the light intensity increases, the percentage of floating discs increases. More light will equal to more discs floating.
Answer:Increase in ambient global temperatures.
Recyling energy to be used again
Regulation of oxygen and carbon dioxide levels
An increase of erosion and siltation along waterways
Explanation:
Conservational biologists think about the preservation of ecosystem by maintaining the environment in a human control way.
Increase in ambient global temperatures.: The humans must prevent the increase in global temperature worldwide by preventing the rise of greenhouse gases which can lead to global warming worldwide.
Recyling energy to be used again: The sources of energy like wood, waste water can be recycled again for reutilization.
Regulation of oxygen and carbon dioxide levels.: The oxygen and carbon dioxide levels must be regulated. As oxygen is the basic requirement for respiration. The increase in carbon dioxide levels due to human activities is likely to cause respiratory diseases and health hazards in living beings.
An increase of erosion and siltation along waterways.: The erosion and siltation will likely to deposit nutrients and debris which may either contaminate the waterway or may cause eutrophication.
