Why is there less biomass at the top of a food web?
7
keeping thermostat set to 68 degrees F during winter months
commercial fishermen use nets to capture many fish that are not able to be used
pH of acid is less than 7' pH of base is greater than 7
carbonic acid
No energy transfer is 100%; with each transfer 90% or more is lost therefore less biomass is at the top of the food web
we must have enough food for over 7 billion people to eat but protect earth's resources at the same time
