A scientist conducted a study on four different species of organisms (W, X, Y and Z) that are related in an aquatic food chain. He estimated the total number of individuals in the population of each species and the average biomass of each individual.
Which of the following shows the correct relation of these species in a food chain?
AZ → Y → W → X
BX → W → Z → Y
CX → W → Y → Z
DZ → W → X → Y
Answer should be ABecause Z is eaten by Y, Y should be eaten by W and W should be eaten by X (looking at the biomass and number of individuals)
