Answer:
<u>protein and lipids</u>
Explanation:
Proteins, like carbohydrates and lipids, are compounds of carbon hydrogen and oxygen. However, unlike carbohydrates and lipids, proteins also contain the element nitrogen and are hence referred to as nitrogenous compounds. In addition to nitrogen, proteins may contain phosphorus or sulphur or both. Some proteins such as haemoglobin contain other elements such as iron.
Answer:
D. Increased sunlight and increased nutrients will increase phytoplankton populations.
Explanation:
Both sunlight and nutrients are required by phytoplankton communities. We know that <u>phytoplanktons</u> are <u>primary producers</u> and they produce food via <u>photosynthetic activities</u>. To carry out photosynthesis, <u>presence of (inorganic) nutrients and sunlight is highly important</u>. In this process, energy is fixed in energy rich molecules such as glucose and organism multiply and/or gain biomass. A decrease in any of them will result into reduced photosynthesis and hence reduced phytoplankton population growth.
