Light excites the electrons in chlorophyll a molecules of photosystem 1. As these electrons move to another primary electron receptor, electrons from photosystem 2 replace them.
Therefore the answer is FROM PHOTOSYSTEM 2.

Answer:
You would find the greatest variety of species in the tropics, and coral reefs. The Amazon basin in South America has the largest area of tropical forests where you could find the most variety of species.
Explanation:
Answer:
E. are found in nitrogen-fixing cyanobacteria AND are used to protect nitrogenase.
Explanation:
Heterocysts are specialized cellular compartments found in nitrogen fixing cyanobacteria. They provide the ideal anaerobic environment for nitrogen fixation since nitrogenase enzyme cant work in presence of oxygen. Hence, in a cyanobacteria both the oxygen requiring photosynthesis process and the oxygen sensitive nitrogen fixation process takes place simultaneously.
Heterocysts have an additional cell wall made of glycolipid that provides a hydrophobic barrier to oxygen. They are involved in production of nitrogenase and other proteins that are required for nitrogen fixation. They also degrade photosystem II which is responsible for producing oxygen and produce proteins which remove any remaining oxygen.
If we were to differentiate anthroprocentric and biocentric views of the environment you could say that anthroprocentric is more holistic than biocentric. They consider the importance of the environment to human beings. Biocentric sees humans as an individual part of the environment.
Also Biocentric views tend to focus more on biotic factors (living things) and anthroprocentric veer towards the abiotic factors (non-living things).
