The Correct Option is A

Solution and Explanation

Trophic structure of ecosystem is a type of producer - consumer arrangement, in which each food level is called trophic level and the graphical representation of trophic structure of ecosystem constitutes ecological pyramids. Pyramids of number and biomass may be upright or inverted, depending upon type of ecosystem but pyramid of energy is always upright because energy of producers is always more than primary consumers and so on i.e., energy goes on decreasing as we move towards apex from base.

Energy Flow through Ecosystems

The energy flow in the ecosystem is one of the major factors that support the survival of such a large number of organisms. For almost all lifeforms on earth, solar energy is the primary source of energy. It is entertaining to find that we receive less than 50 % of the sun’s effective radiation on the earth. When we say effective radiation, we mean the radiation, which can be utilized by plants to carry out photosynthesis.

The energy flow takes place throughout the food chain and food web. During the process of energy flow in the ecosystem, plants being the producers absorb sunlight with the help of the chloroplasts and a part of it is converted into chemical energy in the process of photosynthesis. This energy is stored in different organic products in the plants and passed on to the primary consumers in the food chain when the herbivores consume the plants as food. Then followed by the secondary consumers. Finally, when tertiary consumers consume the carnivores, energy will again be degraded. Thus, the energy flow is unidirectional in nature.
