Observe the ecological pyramid given below, which includes specific quantitative data for each trophic level. Which of the following ecosystems and parameters does this pyramid most accurately represent?

Options

  1. APyramid of numbers in a grassland ecosystem
  2. BPyramid of energy in a freshwater lake ecosystem
  3. CPyramid of biomass in a terrestrial ecosystem
  4. DPyramid of biomass in a marine ecosystem

Correct answer

C. Pyramid of biomass in a terrestrial ecosystem

Step-by-step solution

Based on the given ecological pyramid, we can determine the parameter and the ecosystem by analyzing the units and the shape of the pyramid. 1. Parameter: The values are given in kg m ⁻² , which represents mass per unit area. This is the standard unit for measuring biomass. Therefore, it is a pyramid of biomass. Pyramids of numbers would just have counts (individuals), and pyramids of energy would have units of energy per area per time (e.g., J m ⁻² yr ⁻¹ or kcal m ⁻² yr ⁻¹ ). 2. Ecosystem: The pyramid is upright,
