The species had the same fundamental niche, but the high-altitude species was occupying a perceived niche, as it was inhabiting a different ecosystem, with different adaptations, but being the same species.
<h3>Why is the perceived niche considered a subset of the fundamental niche?</h3>
Well, as we know, the perceived niche is smaller than the fundamental niche, in other words it is a specific portion of the fundamental niche, so it is considered a subset of the fundamental niche.
With this information, we can conclude that the species had the same fundamental niche, but that the high-altitude species was occupying a perceived niche, as it was inhabiting a different ecosystem, with different adaptations, but being the same species.

Answer: circulatory system
Explanation:
Blood that return from the upper and lower parts of the body are deoxygenated hence they are transported to the heart for oxygenation. therefore blood enter the heart through vena cava ( the main vein) to the right auricles and it goes to the lower part of the heart which is the right ventricles which is more muscular. due to this blood is pumped from the right ventricles through pulmonary vein which pumps blood to the left ventricles through pulmonary artery and it is allowed to the left ventricles in the lower part of the heart and it pumped back in the body through the aorta( the main artery) .
