SSC MTS EXAM

Detailed explanation-1: -Energy released from carbon compounds by respiration is used in living organisms and converted to heat. Living organisms cannot convert heat to other forms of energy. Heat is lost from ecosystems. Energy losses between trophic levels restrict the length of food chains and the biomass of higher trophic levels.

Detailed explanation-2: -Answer and Explanation: Energy decreases up the trophic levels because as up the trophic levels, energy is lost through body processes like respiration, reproduction, death, and decomposition due to inefficiencies in metabolism.

Detailed explanation-3: -Energy is lost from the food chain as heat during respiration, due to incomplete digestion, and through excretion of the waste products of metabolism.
