Answer:

Option (A)

Explanation:

Phytoplanktons refers to the marine algae that are responsible for the production of food on which the aquatic species are dependent on. They are the major producers of freshwater ecosystems. This freshwater includes rivers, streams, ponds, and lakes. They are mostly dominated in the upper region of the water body, where they get the necessary amount of sunlight in order to carry out the process of photosynthesis. Some of the examples of phytoplanktons are cyanobacteria, algae, and diatoms.

Thus, the correct answer is option (A).

37. Currently, rooftop solar panels produce only a fraction of the electricity used in the buildings on which they are installed
rewona [7]

Installing active solar energy systems on all available, unshaded rooftop

space and positioning them to face south.

<h3>What is a Solar system?</h3>

A solar system usually comprises of panels which help to collect solar

energy from the Sun and convert them to other forms of energy such as:

  • Heat energy.
  • Electrical energy.

The Passive system optimizes the use of heat or light directly from the sun

while the active systems converts the sun's energy into a more usable form

such as electricity. It is also best to position the panels to face south  

because the Sun is found at this region thereby encouraging maximum

trapping of solar energy.
