[#201] An ecological pyramid of energy flow is, often an inverted pyramid in which of the following ecosystem?
Correct Answer

(B) Ocean

Explanation

Solution: An ecological pyramid of energy flow is, often an inverted pyramid in the Ocean ecosystem. Life on the ocean's surface connects worlds. From shallow waters to the deep sea, the open ocean to rivers and lakes, numerous terrestrial and marine species depend on the surface ecosystem and the organisms found there. In this ecosystem, the standing crop of phytoplankton, the major producers, at any given point will be lower than the mass of the heterotrophs, such as fish and insects. This is explained as the phytoplankton reproduce very quickly, but have much shorter individual lives.

[#202] Adherence of two-children norm shall help in
Correct Answer

(C) Stabilising ecosystem

Explanation

Solution: Adherence to the two-children norm shall help in Stabilising ecosystem.
An ecosystem is said to possess ecological stability or equilibrium if it is capable of returning to its equilibrium state after a perturbation or does not experience unexpected large changes in its characteristics across time. Focusing on the biotic components of an ecosystem, a population or a community possesses numerical stability if the number of individuals is constant or resilient. Adhering to two children will maintain the ratio of population with the availability of resources.

[#203] The method for converting combustible gaseous compounds CO 2 and H 2 O, halogen HX and S to SO 2 , is
Correct Answer

(B) Adsorption method

Explanation

Solution: The method for converting combustible gaseous compounds CO 2 and H 2 O, halogen HX and S to SO 2 , is Adsorption method. Adsorption is a surface phenomenon and does not penetrate through the surface to the bulk of the adsorbent, while absorption involves the whole volume of the material, although adsorption does often precede absorption. It is the adhesion of atoms, ions, or molecules from a gas, liquid or dissolved solid to a surface.
