Explanation:
Answer:
A considerable increase in phytoplankton populations in winter, and a greater increase in spring due to increase in light intensity.
Explanation:
Nitrogen and phosphorus are important nutrients required by phytoplankton populations. The growth of phytoplankton populations is dependent on the level of the availability of Nitrogen and Phosphorus in the presence of sunlight.
A rise in the aquatic coastal levels of nitrogen and phosphorus would result in a great increase in phytoplankton populations in spring, as stimulated by nutrient enrichment coupled with the availability of sunlight during spring. Phytoplankton populations would increase also in winter but not as high when compared to the rise in population in spring
B. going to be refined by further investigation
thats the answer because you need proof that the theroy is wrong
June 21st represents the sun in the sky at noon for the northern hemisphere.
Explanation:
The summer is hotter because the sun's part is higher in the sky. This reason makes the days longer and makes summer sun more intense.
The summer solstice for northern hemisphere occurs in june 21. On this day the sun's position at noon is higher in altitude of the year.
In the summer season , The north pole is tilted towards the sun and this causes the sun's part to be higher in the sky causing the northern hemisphere to receive more light and heat.
