Biomass on the deep ocean floor. energy source or energy sink?
Thermal energy from a sun in another solar system. energy source or energy sink?
Thermal energy from our sun. energy source or energy sink?

Answer 1

The answers are (in respective order);

Energy sink

Energy sink

Energy source

Energy source

An energy sink is a reservoir for chemical compounds that play a critical role in the cycle of these elements. An example is a rainforest which is a huge carbon sink they take carbon diode out of the atmosphere and store it in their tissues . An energy source, on the other, is a source of energy that also powers nutrients and element cycles.

Answer 2

Biomass in the rainforest is the energy sink.

Biomass on the deep ocean floor is the energy sink.

Thermal energy from a Sun in another solar system is the energy source.

Thermal energy from our Sun is the energy source.

Step-by-step explanation:

An energy sink is the component of the physical environment, or more usually any physical system, which captivates some form of energy or matter. For example, a forest functions as a sink for carbon dioxide as it captivates more of the gas in the process of photosynthesis than it discharges at the time of respiration.

On the other hand, an energy source is something like coal, oil, or the Sun that has an application in providing power for heat, light, machines, and others.
