What impact does bleached coral have on the ecosystem in which it lives?

answer question 1-6

1) If the producer level had 1000 Joules of energy in this food chain, how much energy makes its way up to the owl?


2) If the producer level had 10,000 Joules of energy in this food chain, how much energy makes its way up to the owl?


3) If the 2nd Level consumers had 10 joules of energy in this food chain, how much energy was at the producer level?


4) Why doesn't the total amount of energy from the producers make it to the owl? What evidence supports your answer?

5) Other types of birds also form pellets. What would you expect to find in the pellet of a seagull? Explain your reasoning

6)Construct a food chain (with at least 3 organisms) based on what you discovered in your owl pellet. Use your prior knowledge of food chains to fill in any missing parts of the food chain.
