Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
An increase in the number of consumers, including humans, would have what effect on an ecosystem?
A
It would increase the amount of carbon dioxide released in the atmosphere
B
It would increase the amount of elemental carbon dissolved in the ocean
C
It would decrease the amount of fossil fuels that are formed
D
it would decrease the amount of carbon dioxide removed from the atmosphere
Explanation: 

Detailed explanation-1: -By adding more carbon dioxide to the atmosphere, people are supercharging the natural greenhouse effect, causing global temperature to rise.

Detailed explanation-2: -Carbon dioxide is released back into the atmosphere during respiration of consumers, which breaks down glucose and other complex organic compounds and converts the carbon back to carbon dioxide for reuse by producers.

Detailed explanation-3: -When there’s more CO2 in the atmosphere, it makes the atmosphere warmer by trapping heat. Since humans are adding more CO2 to the atmosphere, that helps explain why temperatures are increasing around the world.

Detailed explanation-4: -Animals take in oxygen and release carbon dioxide, as required by aerobic respiration to release energy in the form of ATP. If we had too many animals, more carbon dioxide would be released into the atmosphere while the oxygen levels would decrease.
