Answer:

Option B, by saltation in the first few meters above the land surface

Explanation:

In the process of saltation, sand is carried by air and the sand grains remains suspended for a small distance till the fall down. These sand grains form a parabolic trajectory before falling down. The other characteristics such as height and time of suspended grains depends on grain size, shape, and density, lift & drag force and characteristics of wind such as velocity and turbulence.

Hence, option B is correct

The graph shows the change in number of two populations, lions and zebras. The solid line represents the population of zebras an

9966 [12]

The graph portrays predation. The relationship shows that an increase in the population of zebra results in a subsequent increase in the lion population, and vice versa. This, therefore, means that the lion population is dependent on the zebra population due to an interaction (predation). The lion population will always be lower than that of the zebra because of the inefficiencies of energy transfer up the trophic levels (exhibited by a typical energy pyramid).
