Based on the graph, we would expect the bacterial population to change over time. Initially, growth is exponential. The population curve then levels off; that probably represents the carrying capacity for the population. The curve then turns downward indicating a decline in the microbial population. The decline can be attributed to many factors, both density-dependent and density-independent.
Explanation: Most of the water that evaporates from the oceans falls back into the oceans as precipitation. Only about 10 percent of the water evaporated from the oceans is transported over land and falls as precipitation.
