The correct answer is option B.
This shows commensalistic relationship.
What is commensalism?
Commensalism is a biological relationship (symbiosis) in which individuals of one species profit, while those of the other species suffer neither advantages nor disadvantages.
This is in contrast to parasitism, which is related to parasitism in that the parasitoid has a free-living state and eventually kills its host rather than just damaging it, amensalism, where one is damaged while the other is unaffected, and parasitism, where one is harmed and the other benefits.
The host species, which is largely unharmed, may provide nourishment, shelter, support, or means of mobility for the commensal.

Answer:
The water cycle.
Explanation:
The sun drives the movement of water through a process called the water cycle. In this process, water is evaporated from the sun's heat that reaches Earth. This water rises into the atmosphere in the for of water vapor. This water vapor then collects in the atmosphere along with other particles such as fine dust. This water then precipitates back onto the Earth. Presumably, the water precipitation may fall onto a land formation and integrate back into the ecosystem in the form of ground water or join a steam/river and end up in a lake or the ocean. The water then continues this cycle.
Answer:
The right atrioventricular valve (tricuspid) regulates the opening between the <u>right atrium</u> and the <u>right ventricle</u>.
Explanation:
Valves are gates that allow the connection between atria and ventricles. The two valves located on the right side (tricuspid and pulmonary) direct the incoming blood from the body to the lung, where it is oxygenated; from there it returns to the left atrium, to later pass through the mitral and aortic valves. The left atrium connects to the left ventricle through the mitral valve and the right atrium connects to the right ventricle through the tricuspid valve.
