1 : How do you calculate the adjusted amount of energy that is available to organisms that are one trophic level above producers? 2 : Methylmercury biomagnifies in an ecosystem, meaning its concentration as it moves through each higher trophic level

3 : Scientists are looking to determine the primary productivity of a lake by analyzing its oxygen net primary productivity. How are scientists able to measure how much oxygen is used during a plant’s cellular respiration processes?

4 : Energy transfer is inefficient between trophic levels because

This map shows how climate change might affect precipitation patterns in the great plains of the united states by the end of this century. brown shoes a decrease in percipitation, and blue shows an increase. the maps differ based on the predictive levels of green house emissions. the maps shows that northern area should get a. more pracipations regardless of emmissions b. less pracipation, regardless of emmissions levels c. more precipitation, but only when emission levels.southern areas show a. more pracipations regardless of emmissions b. less pracipation, regardless of emmissions levels c. more precipitation, but only when emission levels.to use these maps to prepare for natural disasters in the great plains, scientist need to ask? a. how many tons of emissions were used at the basis of the map.b. which types of fossil fuels are used in the great plains c. if you think the above is wrong it's probly c the question is cut off

When you run, you begin to breathe heavier and faster. your heart beats more quickly, bringing more oxygen to your cells. which organ systems are working together here?
