Document Summary
In which of the following ecosystems is npp most likely to be limited primarily by nutrients: temperate grassland, tundra, tropical rainforest, temperate evergreen forest, a lentic ecosystem. E is the only one that is an aquatic ecosystem which are most likely to be limited by nutrients. Lecture 11 nutrient cycles and applied ecology. Discuss what steps, if any, have been made to resolve these issues. Global biogeochemical cycles: nutrients carried long distances by winds (gases/particles) and waters (dissolved solutes/particles, c, n, p and s cycles biologically important, altered through human activities. Pool amount of element in component of biosphere (e. g. , trees can be large c pools) Flux rate of movement of element b/w pools (when n gas is fixed and put into a biologically useful form for plants or photosynthesis: e. g. , terrestrial plants = c pool. Climate change can lead to more hurricanes due to ocean temperature (more evaporation occurring)
