First Midterm

Question 1

Iron’s affect on Global Warming

Answer 1

It cause cause an algea bloom in the water which causes a lot of CO2 to be sequestered, but that only works if CO2 is not respiraded and the biomass sinks to the ocean floor then

Question 2

Physiological ecology

Answer 2

adaptations for resource acquisition and dealing with environmental stresses, its the study of animals decision making to
stuff like temperature or light intensity

Question 3

Population ecology

Answer 3

population growth, distribution, and regulation for a certain species
population growth, life histories

Question 4

community ecology

Answer 4

the study of different interactions of species

Question 5

ecosystem ecology

Answer 5

the study of cycles of energy and matter through the abiotic and biotic parts of the ecosystem

Question 6

Mauna Loa

Answer 6

Where the CO2 recordings happen in Hawaii

Question 7

milankovich cycles

Answer 7

is the cycles caused by the natural tilt in the earth

Question 8

pentagram

Answer 8

equals gigton which in 10^15 grams

Question 9

The Suess Affect

Answer 9

It is how to prove that global warming is a really human caused and that is cause the ratio of C14 has gone down in the atmosphere even though, and C14 is radioactive so it has disappeared in the fossil fuels that we are burning, but it has increased in our atmosphere since 1950 because of the atomic weapons testing

Question 10

natural green house affect

Answer 10

without it the earth would be -15 degrees celcius

Question 11

Global warming on sea Rise

Answer 11

from melting land glaciers not icebergs and the sea water expanding because water that is warmer normally is less dense, they are afraid of the artic sheet melting but not really antartic sheet because it is so much colder but if they both melted we would be screwed

Question 12

GPP

Answer 12

Is gross primary production, and is the total amount of carbon that is entering the ecosystems from the autotrophs, it is about twice that of the planets respiration

Question 13

NPP

Answer 13

Is the net primary production which is GPP minus all the carbon that is released through respiration

Question 14

productivity

Answer 14

is the influx of carbon per year

Question 15

NEP

Answer 15

Net Ecosystem Production is the NPP minus the respiration from the heterotrophs

Question 16

AET

Answer 16

Actual Evapo transpiration, which takes into affect both water availabilty, moisture in the air and temperature while PET only takes in temperature

Question 17

Rainforest Limiting Nutrient

Answer 17

Is phosphorus, like the oceans where most of the world is nitrogen

Question 18

Hypoxia

Answer 18

is the reduction of O2 that happens alot in water because there is over fertilization and all of that produces and algea bloom that when decomposes uses up all the O2 causing a dead zone

Question 19

Bottom Up/ Top Up Cascade

Answer 19

The bottom up cascade is when the biomass is determinded by the lowest level on the food pyramid while top up cascade is the opposite

Question 20

Assimilation Efficency

Answer 20

Assimilation over consumtion

Question 21

Production Efficency

Answer 21

Production/ Assimlation

Question 22

Growth Efficency

Answer 22

Production/ Consumption

Question 23

Basal Metobolic Rate

Answer 23

As size increases the basal metabolic rate decreases

Question 24

deposition

Answer 24

is the direct transfer of NO3 to the soil but it only makes up a small part of the nitrogen used by plants

Question 25

nitrogenase

Answer 25

can turn N2 into amino for the plants to use and are found in the nodules of the plants

Question 26

Mineralization

Answer 26

Turning the amino acids in a dead plant to a fourm of Nitrogen that can be used

Question 27

denitrification

Answer 27

is when microbes turn the dead material back into N2

Question 28

Carbon Content in Cultivated Area

Answer 28

When you cultivated the area it releases more carbon because the microbes can get to the dead organism better in the broken soil

Question 29

Anthropogentic

Answer 29

human caused

Question 30

Dark Cycle or Calvin Cycle

Answer 30

Is when they use the electrons from the light to cause a 5 carbon sugar to bind with another carbon using rubisco to fourm a 6 carbon sugar that then it quickly breaks down into 2 PGA 3 carbon sugars

Question 31

Pep carboxylase

Answer 31

Is the enzyme that is used for the C4, that has a higher infinty to CO2 then O2 so it doesnt bind to O2 and that way

Question 32

Compensation point and limitation of biochemical

Answer 32

things

Question 33

Pmax=Imax

Answer 33

Light saturation point

Question 34

Ruderal

Answer 34

fires
