One process that can lower atmospheric carbon is the oceanic carbonic acid cycle, specifically when the oceans have (decreased/increased) carbonate ion concentrations.
What is the main impact of increasing atmospheric sulfur dioxide?
Energy flows unidirectionally through ecosystems, as inorganic molecules and heat during its many transfers up and down between trophic levels.
What is the average residence time for water molecules in the Earth's lakes and reservoirs? Check all that apply. (4 000 years, 1-10 years, 10 years, 10 000 years)
Approximately 99% of non-potable water is locked underground as water or as ice.
Which of the following are ways in which carbon can enter the atmosphere? Check all that apply. (cellular respiration, volcanic eruptions, leaching from minerals or rocks, subduction of tectonic plates)
increasing concentration of stably toxic substances at each trophic level
Which of the following statements about the nitrogen cycle is false? Check all that apply. (Ammonification converts organic nitrogenous matter from living organisms into ammonium (NH4+), Denitrification by bacteria converts nitrates (NO3−) to nitrogen gas (N2), Nitrification by bacteria converts nitrates (NO3−) to nitrites (NO2−), Nitrogen fixing bacteria convert nitrogen gas (N2) into organic compounds)
Global nitrogen enters the living world via nitrogen fixation pathways and it's release by movement of rocks.
decomposition then uptake and use of nitrogen by microbes
Excess agricultural fertilization eventually leaches excess nitrogen and phosphorus to waterways, which leads to overgrowth of photoautotrophs and excessive uptake of nutrients by heterotrophs in a process called
Oysters and clams used to help keep the Chesapeake Bay clean but are less successful today. What is the main cause of this reduction in effectiveness?
Atmospheric sulfur enters the atmosphere from the decomposition of inorganic molecules and burning of fossil fuels by humans.
Where is the largest reservoir of carbon located on earth?
energy that is available to primary consumers uptake of phosphorus nitrogen and potassium
Decomposers are found everywhere on earth where organic matter is found as long as oxygen is present.
lifestyle of breaking down plant and animal tissues and components
