Question

choose the correct answer. what is the main reason why there are \pyramids\ of numbers, biomass and energy in ecosystem structure rather than \squares\,
ectangles\ or other geometric shapes? the reason is unknown. this is due to over - harvesting by humans. the 10% rule accounts for this geometric structure.

Explanation:

In ecosystems, the 10% Rule states that only about 10% of the energy is transferred from one trophic level to the next. This leads to a decrease in numbers, biomass, and energy as we move up trophic levels, creating a pyramid - shaped structure. It is not due to an unknown reason or over - harvesting by humans.

Answer:

The 10% Rule accounts for this geometric structure.
