Answer:
1. C. Ecosystem
Explanation:
An ecosystem consist of living and nonliving things
Convergent evolution suggests different organisms evolved similarly due to similar environments.
Hope this helped!
Answer:
Diffraction
Explanation:
Diffraction is the key explanation why we can hear sounds around corners but not see them. As compared to light waves, sound waves have much longer wavelengths, making diffraction effects much more visible. When the size of the object that the wave is diffracting around is about the same as the wavelength of the wave, diffraction effects become very visible.
Sound has a wavelength of 1 m, while light has a wavelength of 0.1 micro m. Reflection is a secondary reason. Sound waves bounce off walls in a specular way, allowing them to bounce around corners, but light bounces off walls in a diffuse manner.
