What happens to the effenciency of the exchange of oxygen in the human body at a high altitude​
Daniel [21]

Answer:

The effiency decreases at higher altitudes

The higher up a person is on a mountain, the thinner the air is due to the lack of plants that can grow. An example of this is Mount Everest. At a certian point on the mountain, called the "Death Zone", the air is too thin to supply enough oxygen to the human body to survive.

N a jungle habitat, there lives a species of snake, called Species A. The carrying capacity of the jungle allows 5000 of Species
OLEGan [10]

Based on the carrying capacity of the habitat and the changes that occurred in number of the two snake species, correct option is They occupy the same niche and are competing fully for all resources; option D

<h3>What is carrying capacity of a habitat?</h3>

The carrying capacity of a habitat is the maximum number of species the available resources in that habitat can sustain.

The data given of the species of snakes, Species A and Species B, indicate that they are both present in the habitat after a change occurs in the habitat.

Since the population of Species A became zero after Species B was introduced in the habitat, they occupy the same niche and are competing fully for all resources.

In conclusion, the competition between the species of snakes is responsible for the decline in Species A.
