Net primary productivity is calculated as GPP - respiration units of GPP kJ/m2/y which of the following factors is NOT used for quantifying primary productivity over time? change in consumer biomass Which is the portion of energy that an organism uses to maintain its body temperature? respired Terrestrial NPP is greatest in _____ ecosystems, and aquatic NPP is greatest in _____ ecosystems. tropical; coastal Between latitudes of 30° N and 30° S, NPP is primarily constrained by precipitation In aquatic ecosystems, trophic pyramids of biomass are inverted because the standing biomass of algae is lower than the standing biomass of consumers Assimilation energy is the percentage of consumed energy that is digested and absorbed Aquatic ecosystems typically have ¬¬¬¬¬_____ trophic levels, while terrestrial ecosystems typically have _____ trophic 5; 3-4 A trophic level has a biomass residence time of 5 years and net productivity of 3 kg/m2/y. What is the biomass in the trophic level? 15 kg/m2 Chose a logical path for a molecule of water starting and ending in the atmosphere. precipitation, infiltration, evaporation, condensation Which statement is TRUE about the global hydrologic cycle?- Precipitation is greater than evaporation in terrestrial ecosystems. Precipitation and evaporation are about equal in terrestrial ecosystems In waterlogged conditions, anaerobic metabolism of carbon compounds can cause the production of the greenhouse gas methane (CH4) Nitrogen-fixing plants such as soybeans are able to convert atmospheric nitrogen to nitrate and ammonium Which is NOT an example of a major human alteration to the global nitrogen cycle? Animal waste from agriculture Dead zones are formed when rivers that empty into oceans carry excess phosphorus and nitrate runoff. These dead zones are caused by algal blooms Which of the following does NOT significantly affect terrestrial decomposition rates? phosphorus content of litter Decomposition is more rapid in _____ forests because of _____. tropical; increased temperature and precipitation In the study of leaf decomposition in a stream in Germany using leaf litter enclosed in either fine- or large-mesh bags, researchers found that decomposition was strongly affected by invertebrates and lignin content which is not an adaptation to low oxygen aquatic environment increased metabolic activity Match adaptation to benefit prevent loss of leaf tissue produce boundary layer of still air able to take up water after brief rainfall protect plants from slow water loss small leaves with high density veins; spines and hairs; shalllow roots; resin a fish that has tissue solute concentrations that are higher than surround waters is hyperosmotic; trying to not drink the environmental water in attempt to maintain internal water concentrations photosynthesis occurs in two steps known as ___ and the ____ light; calvin why are both CO2 and O2 limited in aquatic environments? not very soluble in water a smallmouth bass swimming in cold water of a springtime lake would likely expend ______ energy than when swimming in warmer water of lake during the summer more the temp that water reaches maxx density 4 degree Celsius rate of biological processes increases two to four times for each ___ increase in temp 10 deg C fish obtain oxygen from the water through their gills using countercurrent circulation which photosynthsis method is best suited to warm dry environment C4 fixation and CAM aquatic organisms have developed streamline shapes to adapt to the viscosity of water a plant with high number of stomata high rate of transpiration the low density of ice allows aquatic plants to survive the winter primary cause of coral bleaching increased water temperature waters polar nature makes it a good solvent T/F adding dissolved compounds such as salt to water increases the boiling point and freezing point false anaerobic condition more common in deep water than shallow spotted salamanders lay eggs in gelatinous masses on twigs partially submerged in small ponds. associated with the eggs scientists have found mutualistic relationship with the developing eggs. what benefit does the salamander receive from this relationship salamander embryos receive increased oxygen supply which does not limit the ability of aquatic plants to photosynthesize high levels of carbonic acid which is not a true statement all ectotherms are poikilotherms which of the following is
