... Carbon dioxide is a waste gas that is produced by this process and it must be removed from the cells because it is toxic to the cells. The movement of both oxygen into the cells, and carbon dioxide out of the cells is carried out by diffusion. Diffusion is a mode of passive transport in which substa ...

Organisms at high altitude
.jpg?width=300)
Organisms can live at high altitude, either on land, or while flying. Decreased oxygen availability and decreased temperature make life at high altitude challenging. Despite these environmental conditions, many species have been successfully adapted at high altitudes. Animals have developed physiological adaptations to enhance oxygen uptake and delivery to tissues which can be used to sustain metabolism. The strategies used by animals to adapt to high altitude depend on their morphology and phylogeny.
