EESA01H3 Chapter Notes - Chapter 3: Primary Production, Arthur Tansley, Landform
Document Summary
Ecosystem: all organisms & nonliving entities that occur and interact in an area at the same time: british ecologist arthur tansley bio entities tightly intertwined with chemical, physical ones. Ecology: the scientific discipline that deals with the abundance and distribution of organisms, the interactions among them, and their interactions with the abiotic environment. Ecosystem ecology: the study of energy and material flows among living and noncomponents of systems. Ecosystem ecologists analyze the structure of ecosystems individual parts & relationships and functional processes. Ecosystems are open systems that receive of energy, process and transform them while cycling matter internally, and produce outputs that move into other ecosystems. Gross primary production: solar energy energy of chemical bonds in sugars by autotrophs. Biomass: organic material of which living organisms are formed. Net primary production: energy that remains after respiration used to generate biomass: ecosystems whose plants convert solar energy to biomass rapidly have high net primary productivity.
