How does the biomass of the autotrophs compare with the biomass of the herbivores?

well first biomass means that energy of source. the autotrophs means the producer, is an organism that produces complex organic compounds. the herbivores are the ones who eats plants.

Microbes outweigh humans by 5,032 to 1!

In order for a food chain to be stable, there must always be less biomass as you go up in trophic levels (i.e. from plants to herbivores to carnivores). This is basically because energy is always...

I'm pretty sure it's something small like 10%. That number also applies to an herbivore being eaten by a secondary consumer.

Biomass may come from photosynthesis: growing of plant matereial. The energy needed for this growths comes from the sun is used to combine the CO2 from the air with water to make carbohydrate and...
