Second Law
400
Each time you go up the trophic pyramid about how much energy do you loose?
About 90%
400
How many secondary consumers does this food web show?

Dependent Variable
400
What is one way that a poikilotherm can regulate its temperature to stay warm?

If you removed the rabbits from this food web, what would be the impact on the ROBINS?
They would increase. If the rabbits disappear, than the plants increase, if the plants increase so do the inchworms. If the plans and the inchworms increase then the robin will also increase because they have more food.
