Ecology question?

Assume a human requires 2000 calories per day. How much daily energy input is required at the producer level to support the carnivorous diet?

    The flow of energy through the ecosystem is part of the food web, each position a organism occupies is called a trophic level.

    About 10% of the energy is transferred through each trophic level contributing to biomass production of the next organism.

    1. Primary production- plants take energy mostly from the sun --1000 calories

    2. Herbivores eat the primary producers(plants)--100 calories

    3. CARNIVORES eat the herbivores-- 10 calories

    4. Apex predators eat other carnivores-- 1 calorie

    So we can say the minimum daily energy input required at the producer level to support a (100%) carnivorous diet is 200,000 calories.

    That is assuming an all meat diet--which is the definition of a carnivorous diet.
