Can someone give a good answer to this second Biology question in more than 100 words?

Question

Biologists in the United States are concerned that populations of many migratory songbirds, such as warblers, are declining. Evidence suggests that some of these birds might be victims of pesticides. Most of the pesticides implicated in songbird mortality have not been used in the United States since 1970s. Suggest a hypothesis to explain the current decline in songbird numbers. Design an experiment that could test your hypothesis.

Answer 1

I won't do your homework for you, but I'll give you some place to start. Just think about the different kinds of things that could impact the populations of animals. Perhaps they are dying because of food scarcity, climate changes, etc. Just google the bird in the example, or phrases like  "migratory bird populations decline" and you should find some articles of interest.

After picking a topic, your hypothesis is the cause you picked. Something like "Bird populations are declining as a result of deforestation and the destruction of their nesting habitats" (keep in mind I made that up, no clue if there is any truth to that what-so-ever).

Then you need to determine - how could I prove, or disprove this? In my example, my experiment might involve determining where the birds nest, and then looking up statistics for forestation in the region in previous years (like the 70's...), then gathering some data on forests.

Maybe this wasn't what you were looking for, but I hope you find it helpful.

Answer 2

its kinda hard to learn anything when you're asking other people to do your hw for you. Why don't you write a paragraph and then post it on here and ask if it sounds okay or if anything needs to be changed?

Answer 3

the excessive use of pesticides has declined the population of  migratory songbirds such as warblers. if the use of pesticides increase the warbler birds population will soon be extinct. however if another non harmful solution for pesticide is used such as pesticide that is non harmful to birds or pesticide that evaporates from the environment, less birds will be harmed and the population of declining birds will increase again. (hypothesis) 69 words. i tried. go to this link and look on page 2 so you can see less harmfrul pesticide and which animals and insects are affected by it. GOOD LUCK.
