Answer:
C. Cutting down forests.
Explanation:
Carbon dioxide is an inorganic gaseous molecule with the chemical formula, CO2. It is naturally released into the atmosphere via a lot of processes. However, CO2 is the most important greenhouse gas as it contributes the most to the global warming effect of the Earth.
The effects of an increase in CO2 concentration in the atmosphere is as follows:
- increase in water contamination and floods
- ocean acidification
- reduction of cold-related deaths
However, the cutting down of forests is not an effect of an increase in CO2 concentration but rather a cause.
The correct answer is adaptive
radiation.
Adaptive radiation is the process by which a single specie or
single ancestral lineage, goes through several or various speciation processes and
then become adaptively specialized to a specific or particular environmental or
ecological place.
Producing genetically engineered crops that are resistant to pests decreases the chance of the crop being destroyed, invaded, or disturbed witch can produce more product. Therefore, more product, faster production and more benefits.
