Solution
The correct option is C B and C only
Pioneer species are those species which are the first one to appear in an ecosystem which has been disrupted earlier. For example - lichens.Sedimentary cycles include those of iron, calcium, phosphorus and other more earthbound elements. It never includes nitrogen. The nitrogen cycle is considered as a gaseous cycle. Secondary succession occurs in a region where the ecosystem has been colonised earlier but they have been distorted by any natural calamities. For example forest fire.The pyramid of biomass in the sea is inverted. Because the productivity of phytoplankton is so high, that a smaller biomass can support a larger mass of consumers.
Therefore, the correct answer is option C.
