Biology (Ecology) Energy Pyramid

Which organism represents the trophic level containing approximately 0.1% of the initial amount of chemical energy produced by the plants?

Approximately what percentage of original chemical energy produced by the phytoplankton would be present in the population of humpback whales?

If 10,000 kcal of energy are present in the grass population, approximately how much energy would be expected in the population of lions?

What happens to most of the energy that is not passed from one tropic level to the next?

If 5,000 kcal of solar energy is converted into chemical energy by the algae population. About how many kcal of energy would be expected in the fish population?
