Question

Consider a food chain with 1,000 joules (an energy unit) available at the producer level. If this food chain is grass -> grasshopper -> lizard -> crow, how much energy is found at the level of the crow?

Answer 1

You take off a zero every step up you go. 1000 - Producer ; 100 - Grasshopper ; 10 - Lizard ; 1 Crow.
