What are heterotrophs and autotrophs?
By: Tami Port MS
Nearly all food ultimately comes from the sun, and living organisms fall into one of two categories, based on specifically how they obtain that nutrition.* What Are Autotrophs? * Plants, and some forms of bacteria, are considered self-feeders. They are able to synthesize their...
