Which of the following statements is NOT true?

Question

1)it is possible for a single fish to occupy both Trophic Levels 2 and 3
2)it is possible for a single fish to occupy both Trophic Levels 1 and 2
3) Apex predators are the population with the fewest numbers and the lowest overall biomass in most ecosystems
4)Trophic Levels rarely exceed 5 or 6

Answer 1

The statement that is NOT true is:

3. Apex predators are the population with the fewest numbers and the lowest overall biomass in most ecosystems.

While it's true that apex predators often have lower population numbers compared to lower trophic levels, they do not necessarily have the lowest overall biomass. In many ecosystems, they may have significant biomass, but their numbers are low due to the inefficiencies in energy transfer between trophic levels. However, it's important to note that their biomass is typically lower than that of primary producers and herbivores.
