Suppose that a species of toads is introduced into a new environment in an attempt to reduce the populations of insects. the toad has no natural predators in the new environment. the toad population would most likely
a) increase exponentially.
b) increase logistically.
c) decrease rapidly and die out.
d) remain the same.

when the displaced particles are perpendicular to the direction the wave travels, is called a transverse wave, whereas in longitudinal wave the displace practices are parallel to the direction of the wave.

in the given image:

first image shows - longitudinal wave

second image shows - transverse wave

third image shows - longitudinal wave

fourth image shows - longitudinal wave
