Trophic pyramids demonstrate the "10 percent rule of ecological efficiency. applying this concept to sustainability, at which level would humans have the smallest ecological footprint?

Answer;

Primary consumer

Explanation;

-The amount of energy at each trophic level decreases as it moves through an ecosystem. Energy can pass from one trophic level to the next when organic molecules from an organism's body are eaten by another organism.

-The 10% Rule means that when energy is passed in an ecosystem from one trophic level to the next, only ten percent of the energy will be passed on. A trophic level is the position of an organism in a food chain or energy pyramid.

-At the primary consumer level the humans have the smallest ecological footprint.

good one: produce hormones that plants grow.

bad one: the problem with organic matter is that while plant nutrients are needed for crop growth, they can also stimulate excessive growth of the wrong plants – mainly, algae.
