Answer:
high clean-energy startup costs
Explanation:
Protecting the environment means improving its sustainability and reducing pollution to the barest minimal. This utterly means terminating every activity that contributes to pollution in the environment, including the source of energy. The most widely used source of energy is the non-renewable source e.g. coal, fuel, etc.
These source of energy, however, release pollutants in form of greenhouse gases, into the environment. One way to eliminate the use of non-renewable source of energy is to adopt the use of renewable sources e.g. solar energy, wind etc. However, one major setback to doing this is the high production cost involved.
Although these sources of energy (renewable) are referred to as green or clean, but they have really expensive startup costs and are unaffordable most times.
Answer:
C3 plants would have faster growth rates; C4 plants would be minimally affected.
Explanation:
C3 and C4 pathways are the variations of dark reactions of photosynthesis present in green plants. The photosynthetic efficiency of C3 plants is reduced due to the affinity of RuBisCo enzyme for oxygen which in turn leads to the futile pathway of photorespiration. RuBisCo enzyme catalyzes the rate-limiting reaction of the C3 pathway. On the other hand, the C4 plants concentrate CO2 around RuBisCo in their bundle sheath cells of leaves to minimize photorespiration and exhibit higher rates of photosynthesis.
Increased levels of atmospheric CO2 would reduce the photorespiration in C3 plants and would allow them to fix CO2 efficiently due to the increased concentration of CO2 around the enzyme RuBisCo. The increased photosynthetic efficiency would help these plants to exhibit faster growth rates.
However, the photosynthetic rate of C4 plants is not limited by CO2 concentration as they themselves reduce photorespiration by spatial separation of primary carboxylation in mesophyll cell and CO2 fixation in bundle sheath cells. Hence, increased CO2 levels in the atmosphere would not have any impact on their photosynthetic rate and growth.
