<u>Answer</u>:
Phytoplankton feed on nutrients brought up by upwelling.
Hence, option D is the right answer.
<u>Explanation</u>:
Phytoplankton are microscopic marine plants, i.e they live in water bodies. They are autotrophic, i.e they prepare their own food. They are called phytoplankton because they absorb photo energy i.e sunlight. They absorb carbon dioxide and release oxygen. As they need to absorb sunlight, they are present near the surface of the water.
Upwellings are ocean currents which bring nutrients from deep cold water to the surface. Upwellings happen because of the rotation of the Earth and winds. The phytoplankton depend on the nutrients brought by the upwellings to prepare their food using sunlight and they form the food for various sea animals.

Answer: Option(a) is correct.
Explanation:
Correct Option : Marginal cost curve above average variable cost for a typical firm in the market.
In a market of perfect competition, the shutdown price of the firms will be minimum point of average variable cost. So, there is supply of goods by the firms if the price is equal or above the shutdown point of the firm.
Therefore, the supply curve of the firm is the above part of the MC curve from the minimum point of average variable cost.
Answer:
9%
Explanation:
WACC is the average cost of capital of the firm based on the weightage of the debt and weightage of the equity multiplied to their respective costs.
According to WACC formula
WACC = ( Cost of common stock x Weightage of common stock ) + ( Cost of preferred stock x Weightage of preferred stock ) + ( Cost of debt ( 1- t) x Weightage of debt )
As WACC is calculated using Market values.
Company Value = 100%
Value of Debt = 28%
Value of Debt = 100% - 28% = 72%
WACC = ( 10.54% x 72% ) + ( 5.27% x 28% )
WACC = 7.59% + 1.48% = 9.07% = 9% (rounded off)
