Ecosystem And Energy

Question 1

Aerobic

Answer 1

Refers to oxygen. Respiration that requires oxygen

Question 2

What is cellular respiration fuel source.

Answer 2

Glucose. The carbon hydrogen bonds get broken and the oxygen acts as an elcron receptor that forms water

Question 3

Decomposes

Answer 3

Types of consumers.

Question 4

Detritivore

Answer 4

Animals that eat large chunks. Decomposer

Question 5

Saprophyte

Answer 5

Bacterium that take small bits and decompose

Use there materials as carbons energy source

Question 6

Energy does what in an ecosystem

Answer 6

Transformed and transferred.

Changes form and then is moved to different places

Question 7

Energy eventually leaves the ecosystem as

Answer 7

Heat or low grade energy

Question 8

All energy transaction lose

Answer 8

Heat.

Internal combustion energy like in cars. A lot of energy is lost as heat and that’s why engines need coolers

Question 9

Gross primary production

Answer 9

Energy converted to chemical energy of organic compounds in agiven amount of time.

Question 10

Net primary production

Answer 10

= GPP -Ra

Respiration autotroph

Only the respiration in the producers cells get subtracted

Question 11

Jet ecosystem production

Answer 11

NEP= GPP-Rt

Total accumulation production

Question 12

Limiting resource

Answer 12

The resource in short supply that will run out first

Question 13

Are temperature and sunlight limiting reagents in the ocean

Answer 13

No

Question 14

In general usually the limiting reagent in marine ecosystems are

Answer 14

Nitrogen or phosphorous. May not be though

Ammonium or phosphate

Maybe iron too

Question 15

Terrestrial ecosystem can be limited by what resources

Answer 15

Light temperature water

Could be other things

Question 16

Trophic levels are the what in food chained

Answer 16

Links. Primary secondary tertiary consumer

Question 17

Where does the Jules (J) come from in A leaf

Answer 17

Sunlight. Some energy gets lost cause of first ow of thermodynamics

Question 18

Hype much energy is wasted or lost in an organisms that’s a primary consumer

Answer 18

Half

Question 19

Assimilated energy is

Answer 19

The energy that is used from consumption.

33% goes toward growth

67% is used for cellular respiration

Question 20

Cellular respiration undoes

Answer 20

Photosynthesis

Question 21

As you go up a trophic level there is less

Answer 21

Energy as you go up because energy keeps getting lost and wasted

Question 22

A very high turnover rate allows for producers to be what compared to consumers

Answer 22

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

Question 23

An energy diagrams has to be

Answer 23

Upright like an actual pyramid

Question 24

The water cycle

Answer 24

All life needs water and this water travels over the biosphere. Operates in al three state solid liquid gas

Question 25

Carbon cycle

Answer 25

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

Question 26

The nitrogen cycle

Answer 26

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

Question 27

Phosphorus cycle

Answer 27

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

Question 28

Trees are important for ehat in run off and ecosystems

Answer 28

Retaining of nitrogen or nitrates

Question 29

Restoration

Answer 29

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
