Answer:
B. the appearance of lichens and mosses in an area where a glacier has recently melted away
Explanation:
Ecological succession, which refers to the series of changes that occurs over time in an ecosystem, can be of two types namely: primary succession and secondary succession.
Primary succession is a succession that involves an area where no form of life has grown previously, hence, the area of land is barren e.g bare rock. Primary succession is first colonized by species called PIONEER SPECIES e.g. lichens, mosses etc.
According to this question, "the appearance of lichens and mosses (pioneer species) in an area where a glacier has recently melted away" is an example of PRIMARY SUCCESSION.
Answer:
A scientific hypothesis can be described as a tentative statement which can either proved to be right or wrong through the support of the experiments being performed.
The possible hypothesis for the theory that Wood Thrush decreases are not due to deforestation can be as follows:
<em>'If the population of the Wood Thrush is not affected by deforestation, then the population of the Wood Thrush will remain the same when deforestation occurs in a particular area.' </em>

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.
