I think A is the right answer because secondary consumers are herbivores. I am 99.9% sure about this.
A. A describes the effect of light intensity on photosynthesis.
Answer: A
Explanation:
In plants and other primary producers, photosynthesis is a biological mechanism that is vital to energy production. Energy-containing carbohydrates are derived from light, water and carbon dioxide in the form of glucose molecules.
The waste product oxygen is released as a result. Photosynthesis depends on many variables, including:
carbon dioxide concentration,
ambient temperature
and light intensity
It is a rate-limited reaction. Since photons or particles of light provide the energy required for the reaction, high intensities of light increase the photosynthetic rate. From the graph shown, as the intensity increases steadily, so does the rate- but at too high of an intensity, it ceases to affect the rate of photosynthesis, which becomes constant or plateaus.
Beyond this point, either the supply of carbon dioxide or the temperature limits the reaction. For instance, at high intensities tissues may even be damaged by high temperatures or heat.
Monosaccharides and the second one is amino acids
I think the correct answer would be option 1. It is the marine life in the Arctic circle that is most affected by the extinction. It was estimated that about 40% of the endangered animals of this part are in extinction. This is because of climate change and the destruction of their homes. Also, scientists say that the temperature change of this area is increasing rapidly as compared to the rest of the world which means the animals would have to adapt to these conditions and while some can adapt easily, there are those that cannot and would die to extinction.
