Protists are eukaryotes, which means their cells have a nucleus and other membrane-bound organelles. Most, but not all, protists are single-celled. Other than these features, they have very little in common. You can think about protists as all eukaryotic organisms that are neither animals, nor plants, nor fungi.
Whitecap and swell are the two types of waves which are generated by moving over of water.
Waves are normally generated by the wind moving over water surface. They indicate the speed of the wind in the area. Swell is the wave which usually with smooth tops and that have moved beyond the area where they were first generated.
Height of waves varies over time. The wave height is calculated statistically as the average height of the highest one-third of the waves that is experienced over time. Swell waves are the regular, longer period waves which are generated by distant weather systems. They may travel over thousands of kilometers distance. A whitecap is a wave formed when the narrow crests of a wave are blown off by the winds. This creates a mixture of air and water.

As succession proceeds in an ecosystem, there is an increase in population density. This is accompanied by the change in the species diversity as well. Thus, the correct option is B.
Ecological succession is the process through which the mixture of species and habitat in an area changes over the period of time. Gradually, these communities of species replace one another until a climax community like a mature forest is reached in that ecosystem, or until a disturbance, like a fire, occurs in that region.
The succession of an ecosystem begins with a pioneer species such as the lichens, some fungi species. Species such as the lichen begins to secrete acids which begin to break the barren land into a number of small particles. The small particles mix with the lichen species remains and starts the process of soil formation. On addition of the soil, more diverse plant species such as bryophytes and pteridophytes grow on the land. Later on, these plants are replaced by the most diverse angiosperm species. In this way, the species diversity tends to increase as a result of ecological succession.
Therefore, the correct option is B.

Answer: B.
Explanation: Ecological succession, quite literally, is the change in the species of an area/ecosystem that had earlier been completely wiped out. Wildfires are a prime example of that.
