Answer: 2. Population bottleneck

Explanation:

A Population bottleneck is a term used to refer to an event that causes the population of a species to reduce in very large numbers. Such an event can be environmental disasters like famine, the overhunting of a species or the destruction of its habitat.

In the case of the Cha-tham Island Robin, the bottleneck event must have been the introduction of cats and rats which then went on to hunt the birds to near extinction.

The density of gas particles in a section of Earth’s atmosphere decreases. Which of the following is the most likely explanation
aalyn [17]

Answer:

<em>A. The air pressure in that section of Earth’s atmosphere decreased. </em>

Explanation:

In the free air, the density of the air diminishes as the air is warmed. On increasing the pressure, the density also increases. The air is packed. The density increments as pressure increments.

The thickness and density of air decline with the increase of height because of that the surface area of the Earth's climate diminishes with increase in height, along these lines gas particles can spread out.

The density of the air is most minimal at a high rise on a hot day when the pressure of the atmosphere is low.
