Question 4 task card 2

Explain why so many trees are needed to support just one lion in the eco-system.

Trees provide food for the 1st level consumers which then feed the 2nd level. There must be alot of trees to feed all the 1st level consumers for them to survive. The lion being the 2nd level consumer doesnt eat all 1st level consumers and so therefore all those extra trees are to provide for other animals.
As shown in the book on page 245 it shows how a food web works and how many producers are needed to suport just one 3rd order consumer.
