Nyah explains to arman the importance of decomposers in an ecosystem. which sentence(s) should she use in her explanation? select all that apply. a.) decomposers provide food for consumers. b.) an ecosystem cannot function without decomposers. c.) most ecosystems have only one type of decomposer. d.) decomposers to recycle nutrients in an ecosystem e.) fungi, plants, and insects are examples of decomposers.

The Sentences Nyah should use in her Explanation are :

B. An Ecosystem cannot Function without Decomposers.

D. Decomposers help to recycle nutrients in an Ecosystem.

Because :

✿ Producers provide food for Consumers.

✿ Ecosystems have many types of Decomposers like Bacteria & Fungi.

✿ Plants are not Examples of Decomposers.

scattering of light by tiny particles in air to produce the colors we see on sky, is dependent on the following factors:

(i) wavelength of light

(ii) size of the scattering particle  

(iii) distance traveled by light through the atmosphere.

according to rayleigh's law of scattering, the amount of scattering is inversely proportional to the fourth power of its wavelength. shorter the wavelength, greater is its scattering. hence violet/blue light is scattered more than red.

sun's light is a composite light ( visible light) with wavelengths in the range 400 nm (violet) to 700 nm (red). as sunlight passes through our atmosphere, the molecules of air scatter light according to their wavelengths. during sunrise and sunset, the sun's position is below the horizon. hence light from the sun travels a greater distance in the atmosphere when compared to its position a noon.

as sunlight enters the earth's atmosphere, blue light is scattered away and at the end of its journey in the sky, only red and orange wavelengths remain in the beam.

hence at sunrise and sunset, the sky appears reddish orange.
