Detailed explanation-1: -If a grassland ecosystem has 10, 000 kilocalories (kcal) of energy concentrated in vegetation, only about 1, 000 kcal will be transferred to primary consumers, and very little (only 10 kcal) will make it to the tertiary level.

Detailed explanation-2: -According to Lindeman’s 10% law, only 10% of energy is transferred to next level. If energy available at first trophic level is 10, 000 Joules, then at second trophic level energy available will be 10% of 10, 000 which equals to 1000 Joules. Was this answer helpful?

Detailed explanation-3: -What is the 10 percent law of energy flow? The 10 percent law of energy flow states that when the energy is passed on from one trophic level to another, only 10 percent of the energy is passed on to the next trophic level.

Detailed explanation-4: -Lindemann gave the ten percent law in 1942. This law states that only 10 percent of energy in a food chain out of the total energy is transferred from one trophic level to another. The rest of the energy is utilized for other metabolic processes and some are released as heat.
