Biomass has the following use:
It is widely available: Biomass can easily be sourced for. It is widely abundant in the environment.
It is inexpensive: Due to its wide availability, its source materials are very cheap and lies readily in the environment when we compare this to exploration for fossil fuels and mining for uranium.
It is carbon neutral: Since biomass constitutes a part of the carbon cycle, energy from biomass does not lead to climate change. Green plants use carbondioxide to manufacture their food and it is released back to the atmosphere when biomass is tapped.
It is environmentally friendly: The use of biomass as a source of energy does not affect the environment negatively. It is a clean source of energy.
It helps to reduce amount of waste: biomass energy helps us put wastes into a very good use.
The correct answer is - D. the Great Australian Bight.
The Great Australian Bight is a body of water that is located south of the Australian mainland. It is spread in most of the southern coast of the continent, and in general it is a shallow body of water that looks like it is penetrating into the continent because in this part Australia has an inward half circular shape. Because it is mainly shallow body of water, and the coast in this part is mostly flat, it is not a place that is suitable for creating ports.
