What is the difference between a species and a population? A species includes only one type of organism, while a population includes many types of different organisms.
A species includes only organisms that can reproduce together, while a population includes groups of organisms that cannot all reproduce together.
Organisms of the same species must live in similar climates, while organisms of the same population can live in different ecosystems with different climates.
Organisms of the same species can live in different areas, while organisms of the same population live in only one area.

Organisms of the same species must live in similar climates, while organisms of the same population can live in different ecosystems with different climates.

one part of the electromagnetic spectrum that arrives on earth as solar radiation from the sun is the visible spectrum. wavelengths of the visible spectrum combine to form what we refer to as

answer - d) ultraviolet radiation.

violet /   380–450 nm / 668–789 thz

violet is number 1 in the chart of visible light.

the circled areas are referred to   as sunspots.   the sunspots are cooler than the   surrounding area.

sunspots are temporary phenomena on the photosphere of the sun that appear visibly as dark spots compared to surrounding regions. they correspond to concentrations of magnetic field flux that inhibit convection and result in reduced surface temperature compared to the surrounding photosphere.
