9. What is a population?

10. What are 3 impacts you have on the environment each day?

Section - II Explain in detail the following

1. Discuss two Ecosystem Services (i.e., pollination, water purification, regulation of the atmosphere, viable fisheries, etc.). What are two ways that each of these services is altered by human activity?

2. Describe two major changes in abiotic factors that will be a part of global warming and note how ecosystems (and the organisms in these systems) will be affected and how they will respond.

3. Fish populations fluctuate over time, depending on many factors. Draw a generalized diagram of population numbers versus time, including increases and decreases. Discuss 5 factors that would influence the success of a population.

4. Outline the pools and fluxes in the hydrologic cycle. Describe two ways in which humans can alter pools or fluxes.
