Question

How might adding trees, other plants, and phytoplankton to the biosphere impact global climate change?

a
The biosphere will absorb oxygen, and the temperature of the atmosphere will increase.
b
The biosphere will absorb carbon dioxide, and the temperature of the atmosphere may decrease or the warming of the atmosphere will slow.
c
The biosphere will absorb oxygen, and the temperature of the atmosphere will decrease.
d
The biosphere will absorb carbon dioxide, and the temperature of the atmosphere will increase.

Answer 1

Answer:

B) The biosphere will absorb carbon dioxide, and the temperature of the atmosphere may decrease or the warming of the atmosphere will slow.

Explanation:

The Climate is constantly influenced by changes caused by the increase in global temperature called Global Warming. Global warming is caused by the emission of green house gases which includes carbondioxide (CO2). Hence, one way to prevent the climate from further deterioration is to find a way of removing gases like CO2 from the atmosphere.

Plants like trees and phytoplanktons like algae are photosynthetic organisms. This means they have the ability to perform the process of photosynthesis, which is the usage of light energy from sun to synthesize food in form of organic molecules (glucose) from an inorganic source. The inorganic source is Carbondioxide (CO2). Plants take in CO2 via the stomata on their leaves. Carbondioxide is a vital raw material for photosynthesis, hence, the photosynthetic process helps remove Carbondioxide from the atmosphere.

If trees, other plants, and phytoplankton are added to the biosphere, they will perform photosynthesis and absorb a good amount of Carbondioxide (CO2), which contributes to global warming, from the atmosphere. Hence, the temperature or warming of the atmosphere caused by global warming will decrease.

Answer 2

Answer:

Option B. The biosphere will absorb carbon dioxide, and the temperature of the atmosphere may decrease or the warming of the atmosphere will slow.

Explanation:

• Phytoplanktons are algae that float on the surface of the water. They contain chlorophyll and perform photosynthesis. They play an important role in the marine ecosystem as they are providers o food to many species of fish and other aquatic organisms.
• Apart from that, the most important role of phytoplanktons are absorption of CO2 and release of Oxygen in the atmosphere.
• Phytoplanktons are the major players in photosynthesis hence, account for the most oxygen production in the ecosystem.
• As we are well aware that the increase and decrease in CO2 and O2 affect the rate of global warming and contribute to climate change.
• Adding, trees, and phytoplankton will keep a check on CO2 and increase the amount of oxygen in the atmosphere resulting in the reduction in the rate of Global Warming.
