1. What is the difference between survivorship curves and the life table? Name and describe the three curves and three types of life tables.
2. Why are there different soil types in the cold deserts and the tundra, and what are their respective soil types?
3. Name 2 natural causes of NO[sub]x[/sub]/SO[sub]2[/sub] and 2 causes by humans.
1. Surviorship curves are graphs that show the mortality rates at each time interval hile life tables are tables that include the probability of an organism dying. So one is a graph and one is a table. 2.Climate and formation? Cold deserts have aridisols while tundra have gelisols and layers of permafrost 3. Lightning and volcanic eruptions. Consumption of fossil fuels and mining.

Correct.
Two years ago I knew stuff about rocks, minerals, experiments, and ecosystems, yay!
Last year I knew stuff about amphibians, reptiles, freshwater, and more experiments, yay again!
Now I'm learning stuff about oceanography, saltwater, and birds, yay for the third time!

1. Name all the steps of the nitrogen cycle and the chemicals and organisms involved.

1. What is the difference between Batesian and Mullerian mimicry?
2. Why do some deserts contain Entisols, rather than Aridisols?
3. How does eutrophication affect the properties of the water it occurs in?
1. Müllerian mimicry is when multiple species share the same warning coloration, but all of them have defenses and Batesian is when harmless species mimics aposematic coloration of harmful one
2.They are very dry
3. Eutrophication increased dissolved oxygen in the water
I mean, your second answer could be wayyyyyy more specific, but other than that, you're good.
Doesn't eutrophication cause hypoxia and not an increase in DO?

Eutrophication can also cause an increase in oxygen during the day. I admit tho, my answer wasn't the best.

1. Name all the steps of the nitrogen cycle and the chemicals and organisms involved.
Fixation: converts atmospheric nitrogen into ammonia or nitrate, can be done naturally thru bacteria(ex: cyanobacteria) or artificially through Haber-Bosch Process.
Ammonification: organic nitrogen converted to ammonia by bacteria or fungi
Denitrification: nitrate is reduced to atmospheric nitrogen by anaerobic bacteria
Assimilation: organisms (mainly plants and animals) incorporate nitrate and ammonia and convert it into organic nitrogen
Nitrification: converts ammonia to nitrate, performed by soil bacteria such as [i]Nitrosomonas[/i]

yeah sounds about right

1. What is the difference between a fundamental and a realized niche?
2. Give 2 pros and cons of a carbon tax.
3. What is a movement corridor and why are they important?
4. What is the difference between the flora of a chaparral and a steppe?

No one's been active on here for a month, so I'll ask some questions:

1. What is the difference between bioremediation and bioaugmentation?
2. What are 2 adaptations of plants to survive in the desert biome?
3. What happens to the birth and death rates of a population after it reaches carrying capacity?
1.) Bioremediation refers to using microorganisms native to the environment in clean ups, whereas bioaugmentation generally introduces new microbes to aid clean up
2.) Taking on waxy cuticles to reduce transpiration and finding ways to store water, such as the barrel cactus
3.) They oscillate; one grows while the other shrinks, and then the other grows while the other shrinks

um that was a long time ago. there r new questions now
