|
|

None of the above
|
Detailed explanation-1: -The biomass in the lower trophic levels is generally very high as compared to the higher trophic levels.
Detailed explanation-2: -Biomass decreases with each trophic level. There is always more biomass in lower trophic levels than in higher ones. Because biomass decreases with each trophic level, there are always more autotrophs than herbivores in a healthy food web.
Detailed explanation-3: -With less energy at higher trophic levels, there are usually fewer organisms a s well . Organisms tend to be larger in size at higher trophic levels, but their smaller numbers result in less biomass.
Detailed explanation-4: -Which of the following statement is true for pyramid of biomass? Explanation: Biomass is a measure of the amount of food available. When animals eat only a small proportion of their food, it is converted into new tissue. This tissue is the food for the next trophic level organisms.
