Answer:
<u>-blue and red light</u>
Explanation:
Plants produce sugars or carbohydrates during the process of photosynthesis. They absorb light energy from the electromagnetic spectrum with pigments within the thylakoid membrane, like chlorophyll a, chlorophyll b.
Chlorophylls are made of ringed molecules chlorine, a hydrogenated form of porphyrin with a magnesium ion bonded to four atoms of nitrogen. Chlorophyll a shows the most absorption of red light (642 nm) and blue light (372 nm); while chlorophyll b shows the most absorption at 626 nm and 392 nm.
Different types of chlorophyll sidechains change the molecules' absorption ranges; A's methyl group is bound at carbon 7, B's aldehyde (CHO) ring is bound at carbon 7. Both absorb light from orange-red and violet-blue wavelengths. As such, the best light wavelengths for photosynthesis are within the blue and red wavelengths (425–450 nm) and (600–700 nm).
Nitrogen,Phosphorus and Potassium
Answer:
B) Changes in the temperature and salinity of water.
Explanation:
<em>Options</em>:
A) Migration of bottom feeders into the region.
<u>B) Changes in the temperature and salinity of water. </u>
C) Migration of fresh water fish to places near the mouths of rivers.
D) Formation of breeding grounds for various species in the shallow waters.
Sea level changes are among the most relevant issues that our planet is facing due to climate change. This phenomenon impacts the salinity and temperature of the ocean because of the melting of glaciers, and ice sheets. Therefore, <u>melting ice alters the level of salinity of the water which, along with temperature, also effect the density of the ocean water, altering ocean currents and productivity.</u> These impacts alter the distribution, behavior, and ecology of marine organisms.
<em>*Note: The melting of the glaciers and ice sheets - result of anthropogenic climate change - has increased sea level.</em>
