Due to its location, Hawaii does not have very many land birds. The Hawaiian honeycreepers are a favorite for many ornithologists. There are over 50 species of honeycreepers that can all be traced back to one ancestor. The level of diversity in an ecosystem can be determined by the frequency of speciation and extinction.
Describe speciation and identify two possible prezygotic barriers of the Hawaiian honeycreepers that contribute to speciation.
If the Hawaiian honeycreepers became extinct, explain how the newly available niches could lead to speciation.
Answers
Answer:
In speciation, organisms evolved with the passage of time.
Explanation:
Speciation is the evolutionary process in which populations of species evolve with the passage of time to become different species from the original one. Temporal isolation and gametic isolation are two possible prezygotic barriers of the Hawaiian honeycreepers that contribute to occur speciation. The newly available niches could lead to speciation of that organisms that tolerate the Hawaiian climatic conditions when the extinction of Hawaiian honeycreepers occurs. The new organisms used the available resources such as food and space etc and increase its population.

When it is summer in the U.S, why is it winter in South America?
Answers
Answer:

Explanation:
hope it helps :)
Answer:
The Earth is tilted at an angle of about 23 degrees, which means that depending on where Earth is on its orbit, one pole will be getting more hours of light (summer) and one will be dark (winter).
Explanation:
Also, the earth is tilted on it's axis so more direct rays of sunlight hit the southern hemisphere making it summer in that hemisphere while it is winter in the northern hemisphere. Six months later, this reverses, and more direct rays hit the northern hemisphere. That's why it's summer here while it's winter there.
The earth's distance from the sun has nothing to do with it. It's all about the axial tilt.
