This chapter is largely a review of ecological principles relevant to marine biology. We will deal with it in summary. Know the following terms and concepts from the chapter:

Terms:

biotic        abiotic        competition        interspecific competition        intraspecific competition            resource partitioning
niche        habitat        ecosystem            symbiont                             commensal                                mutualism
predation                    herbivory            parqasitism                          autotrophs                                heterotrophs
primary prodcuer        consumer            trophic level                        food chain                                    food web
keystone predator        decomposer        dissolved organic matter (DOM)                                        detritus
limiting nutrients            nitrogen cycle     carbon cycle                        nitrogen fixation                        nitrate
benthic                        pelagic                intertidal zone                        littoral                                    sublittoral
bathyal                        abyssal                hadal                                    neritic
 

Concepts:

Know and understand figure 9.16  -  the carbon cycle and figure 9.17 -  the nitrogen cycle. Know the importance of these cycles in limiting biomass and diversity

Know how the concepts of food chains and food webs interlink organisms in a given habitat. Know the few examples of food webs we discussed in class.
