NEET BIOLOGY

Detailed explanation-1: -The amount of energy transferred from a lower trophic level to a higher trophic level always decreases as energy is lost at each step as heat. Only 10 percent of energy is transferred from one trophic level to the next.

Detailed explanation-2: -Solution : Loss of energy from one trophic level to next higher tropic level is 90%.

Detailed explanation-3: -The amount of energy at each trophic level decreases as it moves through an ecosystem. As little as 10 percent of the energy at any trophic level is transferred to the next level; the rest is lost largely through metabolic processes as heat.

Detailed explanation-4: -Toxins found at trace levels in low trophic levels become concentrated (magnified) through the higher trophic levels. If an organism is unable to excrete toxins at the rate it absorbs them, then it will store excess toxins which will later be absorbed by whatever higher trophic level organism preys on it.

Detailed explanation-5: -Trophic Levels and Biomass With less energy at higher trophic levels, there are usually fewer organisms a s well . Organisms tend to be larger in size at higher trophic levels, but their smaller numbers result in less biomass.
