<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:
Annual depreciation (year 1)= $1,400
Explanation:
Giving the following information:
Buying price= $36,000.
Useful units= 300,000 units of product.
Salvage value= $6,000
During its first year, the machine produces 14,000 units of product.
To calculate the depreciation expense for the first year under the units of production method, we need to use the following formula:
Annual depreciation= [(original cost - salvage value)/useful life of production in units]*units produced
Annual depreciation= [(36,000 - 6,000)/300,000]*14,000
Annual depreciation= 0.1*14,000= $1,400
