Hydrological Cycle
When water rains down, we call this...
Precipation
Through which process do living organisms release carbon into the atmosphere?
Cellular respiration
The phosphorus cycle passes through the atmosphere... true or false?
False
Nitrogen fixing bacteria turn atmospheric nitrogen into what form?
Ammonia
This cycle is about rocks and poo
Phosphorus
When water vapor in clouds gets ready to rain down, we call this...
Condensing or condensation
What are 2 examples of carbon sinks?
The oceans and the forests
The permafrosts and glaciers
Who or whats is the natural reservoir of phosphorous?
Rocks
Plants assimilate nitrogen in what forms?
Nitrates and nitrites
Lightning, legumes, and bacteria are a part of the... (which cycle)
Nitrogen
When water is moved through the leaves of a plant and goes back to the atmosphere, we call this...
Transpiration/Evapotranspiration
The initial energy that propels the carbon cycle is the Sun. True or false?
Where is phosphorus found in the human body?
In ATP and in the phospholipid bilayer.
Bacteria turn atmospheric nitrogen into a form of nitrogen usable by plants through the process of...
Nitrogen fixing or nitrogen fixation
Decomposers like bacteria and fungi are exceptionally important in this cycle...
Nitrogen cycle
How is the water cycle related to the carbon cycle?
With photosynthesis and cellular respiration
The carbon reservoir most affected as a direct result of human activity (aka fossil fuel use) is the...
Atmosphere
Which one of the following is the simplified sequence of phosphorus cycling in a terrestrial ecosystem?
a) Soil → Producers → Rock minerals → Consumers → Decomposers
b) Rock minerals → Soil → Producers → Consumers → Decomposers
c) Rock minerals → Decomposers → Producers → Consumers
d) Decomposers → Rock minerals → Consumers → Producers
b) Rock minerals → Soil → Producers → Consumers → Decomposers
The phosphorous cycle starts with rock materials and ends with the decomposers. The phosphorous enters the ecosystem through rock minerals and, there is a negligible exchange of gaseous phosphorus between organism and environment.
When bacteria turn forms of nitrogen back into N2 gas for the atmosphere, we call this...
Denitrification
Which element is a major constituent of biological membranes, nucleic acids, and cellular energy transfer systems?
Phosphorus
The amount of water on Earth is
Always the same
How and why are producers and consumers important to the carbon cycle?
They add (consumers) or remove (producers) carbon dioxide back to/from the atmosphere by performing cellular respiration (consumers) or photosynthesis (producers).
The phosphate by weathering of rocks firstly becomes available to which organisms?
a) Decomposers
b) Consumers
c) Producers
d) Detritivores
c
The phosphorous enters in the ecosystem through the weathering of rock minerals. This phosphorous then enters soil that is taken up by the producers. Then it is passed on to consumers and then to decomposers.
Choose the correct order of events in the nitrogen cycle.
1. Nitrogen is in air, bacteria fix nitrogen, animals get nitrogen from plants, animals die and decompose.
How are humans negatively impacting the nitrogen cycle?
By creating too many synthetic fertilizers that overpower ecosystems.
