For example, a forest of trees and undergrowth plants, inhabited by animals and rooted in soil containing bacteria and fungi, constitutes a biological community. A brief treatment of biological communities follows. ... The various species in a community each occupy their own ecological niche.
Answer:
750m/s
Explanation:
The wavelength of a wave can be calculated by using the formula:
λ = v/f
Where;
λ = wavelength (m)
v = speed of wave (m/s)
f = frequency (Hz or s-¹)
According to the information provided on the wave in this question, λ = 5m, f = 150Hz, v = ?
v = λf
v = 5 × 150
v = 750m/s
Hence, the velocity of the wave is 750m/s.
The answer is D BECAUSE WITHOUT ENEGY THE BALANCE WILL NOT BE OK SO IT CAN COMBUST
