Exercise 1

Part 1

 How does a class being conducted online instead of on campus increase or decrease the classes' contribution to the carbon cycle during the term? Consider the differences between the two in terms of methods of travel, and use of facilities, energy, and other resources.

Answer: An online class will decrease the contribution to the carbon cycle during the term, this is because when a class will not be conducted on campus it will decrease the travel of the students and thus the use of gas will be less by those who use their personal conveyance and for those who use public transport the optimal utilisation of resources will be there as less brakes leading to more fuel efficiency. In terms of energy and other resources, the use of the power in terms of electricity and water will be reduced and thus we can save an adequate amount of energy. When on campus classes are being conducted, everything is being utilize and being taken advantage. Thus this misuse of the resources can be limited and thus it will help in reducing the energy.

Part 2 I took the quiz as assigned and it says that we would 0.00 Earths by the living that you live. Rest you can check my results on the link given below.

Exercise 2  Using ONE ecosystem from the list below, explain the role of the carbon, hydrologic, phosphorus, and nitrogen cycles in this ecosystem.

Choose from a "normal": tropical rain forest, tundra, river delta, or savannah

Answer: I would like to study the eco-system of tropical rain forest and according to me I think that

1) The carbon cycle is a vital part in an ecosystem of the forests. The trees and other plants in the forest are dependent upon the carbon dioxide (CO2) for a process commonly known as photosynthesis. Other things found in the forests, seem...
