NPP = GPP – R
Net primary production =
______________
= GPP – energy used for cellular respiration
Gross primary production = ________________ production of
primary producers
Respiration = ______________________
Thus NPP is the amount of energy available to primary
consumers = primary production
Explain the different ways in which primary production is
influenced in terrestrial and aquatic ecosystems
Primary production: terrestrial
ecosystems influenced by water, temperature, and
nutrient availability
Evapotranspiration rate measures the amount of
water entering the atmosphere...
Using what you know about the transfer of energy among trophic levels
Using what you know about the transfer of energy among trophic levels, explain why there are so few top predators compared to the organisms in the other trophic groups (e.g. producers, primary consumers, secondary consumers) within a given ecosystem?

Ecosystems How is food chain different from a food web? Explain the difference between gross primary production and net primary production? What is the role of plant metabolism (respiration) in productivity? Why is energy lost from a food chain? Where does it go? Is it destroyed'? What limits NPP? What patterns exist in NPP in oceans vs terrestrial ecosystems? Are nutrients involved with NPP? Which ones? What trophic level (group of organisms) is needed for every ecosystem? What do the...

Briefly explain what the greenhouse effect is and how it affects all life on our planet. Additionally, what are two pieces of evidence introduced in class that demonstrate climate change is “real”? Explain what happens with the total energy of the system at different trophic levels, indicating how much energy is transferred from one level to the next. Add a pesticide to your food chain and explain what happens with certain persistent chemical residues at different trophic levels.

Define and provide examples of the following concepts: Environment, ecosystem, abiotic and biotic factors, natural and experimental boundaries, flows of matter and energy. Explain how the boundaries of an ecosystem may differ from those like national parks, county, state or national borders. Explain how natural features of the landscape (ex: a watershed) or biological phenomena (ex: a species range) can be used to define the boundaries of an ecosystem. Explain how ecosystems vary in size and scale, and how some...

to show how the expected major organic products form.
you should draw and explain (what is happening and
why) at each of the steps in the reaction using
the proper terminology. please use accurate lone pair electrons,
formal charges, and accurate electron pushing arrows
throughout.
