Suppose a friend says that we don't need to worry about the rising temperatures associated with global climate change. her claim is that increased temperatures will make planktonic algae grow faster and that carbon dioxide (co2) will be removed from the atmosphere faster. according to her, this carbon will be buried at the bottom of the ocean in calcium carbonate shells. as a result, the amount of carbon dioxide in the atmosphere will decrease and global warming will decline. comment.'
a) primary producers usually grow faster when co2 concentration increases, but to date they have not grown fast enough to make co2 levels drop. b) primary producers usually grow slower when co2 concentration increases, so to date they can't make co2 levels drop. c) primary producers grow fast enough to make co2 levels drop even today. d) primary producers don't remove co2 from the atmosphere.

The correct answer is option A) "Primary producers usually grow faster when CO2 concentration increases, but to date they have not grown fast enough to make CO2 levels drop".

Explanation:

It is true that primary producers, including planktonic algae, growth faster at rising temperatures and at high CO2 concentrations. However, it is not valid to assure that this response from primary producers will remediate the effects of global climate change. We have no evidence of an atmospheric CO2 concentration drop in the last years, even though we have evidence of rising temperatures. Therefore, we should consider that there are several conditions affected by global climate change, and primary producers growing faster is not enough to remediate them.

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.
