None of the provided options are reasonable. <span>comparing nutrient concentrations between the photic zone and the benthic zone can not tell you whether differences in concentrations between the photic and benthic zone are due to uptake by phytoplankton or because nutrients are sinking to the sea bottom and ocean stratification is preventing mixing. The approach of c</span><span>ontrasting nutrient uptake by autotrophs at different locations under different temperatures would not provide useful information on limiting nutrients. but rather uptake rates at different temperatures. It is likely that e</span>xperimentally enriching some areas of the ocean and compare their productivity to that of untreated areas can provide an indication of limiting nutrients, but this is not advisable, as it would have to be done on a large scale, and one cannot be sure of the ecological consequences. Also, because it would not be a controlled experiment, other factors could create 'noise' in the data. The last option, <span>observe antarctic ocean productivity from year to year to see if it changes, also does not help, as there is no correlation between nutrient concentrations using this approach. The best approaches would be either the last approach, but with the additional monitoring of nutrient concentrations, or under a controlled laboratory experiment.</span>
Answer:
Oxygen, air, oxygen from the air, oxygen from air and the second part is synthesis
Explanation:

In photosynthesis, carbon dioxide is reduced. This reduction occurs during the Calvin cycle. The energy for the reduction is gained from Light reaction.
<u>Explanation:</u>
The pigment called Chloroplasts that are present in plants helps them in the conversion of light energy into chemical energy. This pigment contains electrons has higher energy that will be transported in the photosynthesis p[process.
The main source of this process to take place is energy that is obtained from sun. Chlorphylls abosrb the solar energy.The electrons in the chloroplast produces NADPH and ATP. This process is called as the light reactions as the main source of this reaction is light.

Answer:
The experimental results cannot be reproduced.
Explanation:
The ability to follow a specific set of procedures and achieve the same results is one of the key parts of the scientific method. If the results cannot be replicated, the study is invalid. Unfortunately, results of invalid studies are sometimes announced to the public before replication attempts can be made to invalidate the study. Trying to reverse public belief at that point can be impossible.
