Food Webs and Trophic Cascades
Now that we know about nutrient cycling, we are ready to look at food webs as a whole. These represent feeding relationships within a community.These relationships designate certain trophic levels, so let's learn about what these mean...

Energy Flow and Nutrient Cycling in Autotrophs and Heterotrophs
The biosphere is an extremely dynamic system, with energy flowing from one group of organism to another at all times. How does this flow operate? How do nutrients cycle? What is biomass? What are gross and net primary productivity? Let's...
