Two ecology questions please answer?

Question

question#1- in a food web,if the number of food chain connections is decreasing,you 'll find more

1-species

2-herbivores

3-unrelated spescies

4-carnivores.

question # 2-

which of the following will cause a predator-prey relation to be thrown off balance?

1-food levels remain steady.

2-faster reproducton in prey than in predators.

3- equal reproductiov rates in both species.

4-a third neutral species is introducted into the environment.

please give sure answer.

thanks in advance.

Answer 1

dont  like your question

why cant you ask a normal question instead of give wrong choices

A=question#1- in a food web,if the number of food chain connections is decreasing,you 'll find subsequent species disapear as well

B=question # 2-

which of the following will cause a predator-prey relation to be thrown off balance?answer           thedisapearance of links on which susequent specie exist,e.g kill themosquitosand evrything that follows will     disapear ,they sprayed for mosquitos on the banks of the Danube         andallof the life       in the wood disappeared,

you left out all the main reasons for exstinction ,like the loss of habitat,climate change,dissease,and desertification,hunting,population growth etc.

here is a general note on exstinction for your interest ,the answers you want may be in there somewhere

of the earth's estimated 10 million species, 300,000 have vanished in the past 50 years. each years, 3,000 to 30,000 species become extinct.

a lot of human activity is speeding that up since we tend to overpower all the other species in one way or another.

some reasons why animals are being wiped out ,in the forrests are:

the hunting of exotic species for the consumer market

only about 10% of the animals caught survive

the hunting of animals for food by settlers

forrest fires ,that have started because of slash and burning of forrest ,to clear the land for farming, had gotten out of control

the loss of Habitat because the conditions have changed ,e.g less humidity because of surrounding farmlands ,or overpumping of rivers for human use(farming and utility)

because of contamination of the waters ,

expanding populations and expanding farming ,that has to keep pace with the expanding populations are very strong forces that encroach upon the rainforest's

clearing them for farming and settlement areas .

In Mexico is a famous jungle that the Media has been trying to save for years

the Naturists ,and the government ,keep watch .laws are made for protection the wild and to forbid logging.

TV put out a series of documentaries

there are campaigns in the News papers

and all of this has not made the slightest difference

Rainforest's always are in third world countries and always in third world countries corruption and the need for money s highest

the jungle gets smaller by the day

more and more farmers move in .and burn the trees

it is an impossible situation

as long as there is poverty in these regions the destruction will continue

and the Animals will continue to be trapped ,as long as people keep buying the exotic animals

CLIMATE CHANGE

And now many animals are becoming sick because of changes in temperature ,

vital links in the food chains are disapearing affecting other species further along in the chain

90% of the feral (wild) bee population in the United States has died out.

Recent studies in the United Kingdom and the Netherlands have shown that bee diversity is down 80 percent in the sites researched, and that "bee species are declining or have become extinct in Britain." The studies also revealed that the numbers of wildflowers that depend on pollination have dropped by 70 percent.

If bees continue to die off so would the crops they support and with that would ensue major economic disruption and possibly famine.

Bees are not the only polinators but if these things are happening to bees we can bet on it that other insects are also in trouble ,on top of this many people are spraying for mosquitos ,with drastic effects .

so much follows the insects in the food chains ,that we can expect a lot of very bad changes in the environment .

only time will tell what is in store for us ,and that time is running now .

everything is happening so fast it is not possible to monitor events any more
