Document Summary

Primary consumers, so they eat live plant materials. Omnivores: primary = plant secondary = herbivores tertiary = carnivores scavengers = dead material. Primary producers takes sunlight to make energy for them to consume. So much more biomass at primary producer level. Biomass decreases as you go up the trophic level. When you eat an animal or plant material, you can"t convert all 100% of it into energy. Assimilation efficiency = being able to break down the material for energy. Leaves, twigs, or structural component of the plant. Patchily distributed = only found in various places at different time. Foregut = stomach, used for storage, maceration (add fluid for softening) Hindgut = complete digestion, absorb water and electrolytes. Short intestine as digestion doesn"t take that long. But in adults, they are carnivores where they tend to swallow prey whole, so they need a large stomach to take their food in.
