I have a couple of questions for my homework that I have know idea want the answer is?

Question

1. Explain how human population affects other species on Earth?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
2. Explain how an exotic species can effect other species?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
3. How could the extinctin of a species effect your life in 20 years?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
4. If you were given I million dollars toward saving a species on Earth,what would you do with it and why? Explain your answer.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

*If you answer all of them right I will vote you best answer and give you five stars.

Answer 1

1. As the human population increases, the demand for more houses and shelter increases. Sooner or later we'll run out of room in our towns and cities to build houses so we'll tear down other species' homes to make room for ourselves, thus getting rid of their habitat.

Answer 2

1.Other species on Earth can be affected by human population because if a place gets to crowded they can cut down trees and even kill the creatures. The creatures can also die from all the smoke the workers use to make a city or town.

2.Exotic species of animals can be affected by other species because the exotic animals could carry diseases.

3.The species could have helped you by eating flies in your garden or you could've eaten the spicies. The species also could have eaten unwanted vines or even weeds.

4. If I was given 1 million dollars to save a species I would save spiders. Not many people know this but spiders are helpfull because they help plants reprouduce. Spiders also eat unwanted bugs that can be quite harmfull.

Answer 3

1. We effect them by hunting and killing them for food; we destroy their habitat through deforestation, farming and building in their native territories, thus reducing the carrying capacity of the geographic region they occupy. We introduce species from other regions which are predatory or with which they are not adapted to compete.

I'm sure you get the idea. You can come up with more yourself.

2. This is an interesting question, because there are several things going on in the country right now which involve the invasion of foreign species who are either out-competing native species or are breeding them out of existence. Have you ever heard of kudzu or African honey bees? Kudzu is a plant which was introduced by Japan to the United States through the Centennial Exposition held in Philadelphia in 1876. It is remarkably well adapted to the climate in the southeastern U.S. and is wreaking havoc with native plants and trees there. Kudzu was declared a weed by the U.S.D.A. in 1972 and efforts are being made to eradicate it or at least control it. Here's an interesting article about kudzu:

African honey bees are a particularly aggressive type of bee which apparently were exported to Brazil from Africa during the 1950's. They escaped into the wild and have been advancing north and south steadily and reached the U.S. in October 1990. African honey bees have been interbreeding with our European variety and apparently, African traits are dominant over European traits, so bee experts and apiarists are afraid that important European honey bee characteristics will be outbred by the Africans and they will become more difficult to manage, among other things. Here's an interesting website about them:

3. This is related to question 2. If you have been listening to the news recently, you should be aware that a strange phenomenon has been occurring. Honey bees have been disappearing by the colony recently in the U.S. Scientists and apiarists are at a loss to explain why. But they know one thing, that is, if this trend continues, it could spell agricultural disaster for the U.S. Honey bees pollinate not just flowers, but important agricultural plants and trees as well. In 20 years if an explanation has not found for their disappearance and a way found to reverse it, we may well be living in a much different world. Can you imagine a country where a large percentage of the vegetation has vanished because honey bees no longer exist to carry pollen from plant to plant? Fortunately, other bees could be imported from Europe, but there is no guarantee they won't go the way of their predecessors as well.

4. This question I will leave up to you. This is one which demands your own thinking and reasoning skills be put to use.

Answer 4

First, you should always say the TRUTH. you posted in ur questions that there are only a couple of them. A couple means only 2. Now we r ending up with 4 questions.
