Answer:
Heterotrophs
Explanation:
Heterotrophs are organisms that are not able to form their own source of energy and are dependent on others to gain energy. Most of the algae are autotrophs which uses light energy to make organic energy source.
Some algae are heterotrophs that do not require sunlight and pigments as they do not make their food on their own and utilize sugars manufactured by other plants and algae.
They are also called colorless algae as they do not possess pigments. These heterotrophic algae are consumers, not producers. Therefore the correct answer is heterotrophs.
One difference between mechanical and electromagnetic waves is that mechanical waves need a medium to pass through (solid, liquid, gas). EM waves can travel through matter or though a vacuum. In regards to telecommunications, EM waves can be radio waves, these are used in TV's, phones, computers, radios. Mechanical waves somewhat relate to this since radios produce sound;so an EM wave would turn into a mechanical vibration inside a speaker then sound would be produced.

Explanation:
All of this extra carbon needs to go somewhere. So far, land plants and the ocean have taken up about 55 percent of the extra carbon people have put into the atmosphere while about 45 percent has stayed in the atmosphere. Eventually, the land and oceans will take up most of the extra carbon dioxide, but as much as 20 percent may remain in the atmosphere for many thousands of years.
The changes in the carbon cycle impact each reservoir. Excess carbon in the atmosphere warms the planet and helps plants on land grow more. Excess carbon in the ocean makes the water more acidic, putting marine life in danger
