B.) midlatitude broadleaf an mixed forest
C.) alpine tundra
D.) midlatitude grassland

3.) At continude rates of speies extincition, it is possible half of the specie currently on earth could be extinct in _____ years.
A.) 900
B.) 100
C.) 400
D.) 1400

Answer 1

Question 1 eliminate answer A right off the bat. Dynamic and passive are opposites and that does not make sense to be both at once. If we eliminate A then we can eliminate E as well. That gets you a 1-in-3 chance right there. If you can figure out if soil is all inorganic or not, that cuts your odds even better (if it is not all inorganic, that means there is organic-biologic elements).

The world's breadbasket is the central plains states of the U.S. and the Canadian provinces north of these states. It is known as the world's breadbasket because of the amount of wheat and cereal grains grown there exceeds local demand. This excess is sold internationally. Now all you have to do is decide what kind of growing conditions the area has. Forests are tree covered, which make growing crops between the trees difficult. Tundra is not going to let much grow there due to the ice.

At the rate we are currently killing off species, A and D can be eliminated right off the bat. You have to figure out how many species are alive and how fast they are becoming extinct to figure out the answer.

Answer 2

Assuming this is a means to answer some type of homework questions, you will gain much more from doing quick research on your own. Simply getting others to answer will not help you in the long term.

For #1, first figure out what soil is composed of- that will rule out one possible answer. Letter C is greatly misspelled, I am not sure what you are referring to.

#2- Use the US as an example... what in type of environment do we grow most of our crops?

#3- You did not provide what the assumed rate is. Once you have that rate and the number of species on earth, divide total number of species by two (half species) and divide that number by the rate (species per year or whatever the units are).
