Because the higher the food chain gets, the less energy is being transferred , therefore, there are less organisms at the top of the food chain.
I think its arroyo.
i hope this answer is correct and helps you :)
Diffraction occurs when a wave moves through an opening in a barrier. This causes the wave to change direction and spread out.
Waves can behave in three different ways depending on the obstacles they encounter. They can reflect, refract or diffract. In diffraction, waves such as sound, light or water either bend around small objects that obstruct their passage or spread out as they travel through a gap in the barrier.
The degree of diffraction forms a direct relationship with wavelength. It generally increases as wavelength increases. Conversely, the amount of bending lessens as wavelength decreases. However, if the opening of the barrier is smaller than the wavelength, the effect of diffraction is not easily observed. Hope this helps.
Yes they will have to learn about the other branches of biology so that they can have more background knowledge on evolution and can also have facts to back the fact that evolution is true
