Why is biomass a better alternative to coal?A. Biomass does not release carbon dioxide.
B. Biomass is not radioactive.
C. Biomass does not need to be burned.
D. Biomass can be regrown quickly.

Answers

Answer 1
Answer:

Biomass is a good fuel alternative and has many advantages over the usage of coal. The most important is it is renewable and can be grown quickly. Option d is correct.

Biomass is an alternative fuel source. Biomass can be used to make biofuels and biogas. Coals are fossil fuel which means that they are formed from the fossilized remains mainly of trees and algae etc of the carboniferous period  which was  286-360 mya. Which is why their presence on the earth is limited and they are soon bound to get exhausted.

These have lesser carbon dioxide emissions as compared to coal but they do have a carbon footprint. Additionally, while it is true that biomass can be used without being burnt through processes like anaerobic digestion and the resulting biogas/biofuel can be used to generate heat and electricity. This process can have a significant carbon footprint if not done properly.

Biomass can be used to generate biofuels that can be less polluting if utilized properly, However the fact that they are renewable and their production can be controlled is the most important.

Hence it can be concluded that biomass is better than coal because it can be grown quickly. Correct option is d.

Describe how deforestation might contribute to global warming.

Answers

Deforestation may contribute to global warming as the more trees you chop down the higher the carbon dioxide in the air, as the trees take in some carbon dioxide so when you chop down trees the carbon dioxide levels increase making the gloabl warming increase

Global warming can be affected by deforestation because the removal of tress affects the level of carbon dioxide in the environment. The level of carbon dioxide increase with a decrease in the number of trees that cause global warming.

Further Explanation:

The deforestation or the removal of vegetation from the shore can result in soil erosion. The soil erosion will result in the loss of nutrients rich soil. These nutrients are essential for the development of algae and plants. Global warming is a serious concern because of two reasons: Rapid warming of the Earth leads to rapid environmental changes making it difficult for species to adapt. Over time, natural habitats have become limited because of the resilience to climatic changes caused by global warming. The increased human population leading to urbanization and deforestation resulted in these changes. The increase in the human population leads to an increase in their needs for survival. They started to disrupt the food chains by removing predators. They hunted animals for food and other needs. They removed trees for their shelter. These human activities lead to a change in the environment and habitat.

Old grouth forests are full of sick, diseased and decadent trees?

Answers

That is false. An old-growth forest — also termed primary forest, virgin forest, primeval forest, late seral forest, or (in Britain) ancient woodland — is a forest that has attained great age without significant disturbance and thereby exhibits unique ecological features and might be classified as a climax community.
