Ecosystem And Energy Flashcards
Aerobic
Refers to oxygen. Respiration that requires oxygen
What is cellular respiration fuel source.
Glucose. The carbon hydrogen bonds get broken and the oxygen acts as an elcron receptor that forms water
Decomposes
Types of consumers.
Detritivore
Animals that eat large chunks. Decomposer
Saprophyte
Bacterium that take small bits and decompose
Use there materials as carbons energy source
Energy does what in an ecosystem
Transformed and transferred.
Changes form and then is moved to different places
Energy eventually leaves the ecosystem as
Heat or low grade energy
All energy transaction lose
Heat.
Internal combustion energy like in cars. A lot of energy is lost as heat and that’s why engines need coolers
Gross primary production
Energy converted to chemical energy of organic compounds in agiven amount of time.
Net primary production
= GPP -Ra
Respiration autotroph
Only the respiration in the producers cells get subtracted
Jet ecosystem production
NEP= GPP-Rt
Total accumulation production
Limiting resource
The resource in short supply that will run out first
Are temperature and sunlight limiting reagents in the ocean
No
In general usually the limiting reagent in marine ecosystems are
Nitrogen or phosphorous. May not be though
Ammonium or phosphate
Maybe iron too
Terrestrial ecosystem can be limited by what resources
Light temperature water
Could be other things
Trophic levels are the what in food chained
Links. Primary secondary tertiary consumer
Where does the Jules (J) come from in A leaf
Sunlight. Some energy gets lost cause of first ow of thermodynamics
Hype much energy is wasted or lost in an organisms that’s a primary consumer
Half
Assimilated energy is
The energy that is used from consumption.
33% goes toward growth
67% is used for cellular respiration
Cellular respiration undoes
Photosynthesis
As you go up a trophic level there is less
Energy as you go up because energy keeps getting lost and wasted
A very high turnover rate allows for producers to be what compared to consumers
Have less biomass meaning that there is fewer of them compared to the primary consumers that eat them. Most of the producers get eaten almost as soon as they are produced
An energy diagrams has to be
Upright like an actual pyramid
The water cycle
All life needs water and this water travels over the biosphere. Operates in al three state solid liquid gas
Carbon cycle
Producers use carbon dioxide from the air and make food.
Organisms use that food to respiration and release carbon. Organisms need carbon because it makes up the biological macromolecules that all life needs. Polypeptides polynucleotides. Polysaccharides lipids carbon containing organic macromolecules
The nitrogen cycle
All organisms need nitrogen but can’t use nitrogen gas because of triple bonds they form.
Denitrifying and nitrifying bacteria make the cycle continue
Nitrogen is apart of amino acids and allows for proteins which do all the important jobs within a cell. Nitrogen is also in RNA and DNA. Makes up nitrogenous bases guanine thymine cytosine adenine
Phosphorus cycle
Acts more locally because phosphorus doesn’t acts at a gas
Important for phospholipids
Important for DNA and RNA for phosphate sugars
ATP requires phosphate to store energy for cells
Phosphorilating a protein changes it’s shape causing it to turn on or off
Trees are important for ehat in run off and ecosystems
Retaining of nitrogen or nitrates
Restoration
Augmentation - kind of restoration to replace-good things that have been removed usually with the help of organisms. Like legumes planted for nitrifying soil. Bio augmentation
Remediation- taken out the bad things in the ecosystem can also use organisms. Bacteria can often be used to eat the bad things or tolerate them and transform them to be cleaned up. Like oil spills
