    Objetivos de aprendizaje

    Después de completar esta sección, debes conocer:

    • qué se entiende por los términos: ingestión, digestión, absorción, asimilación, egestión, peristalsis y quimo
    • las características, ventajas y desventajas de una dieta herbívora, carnívora y omnívora
    • las 4 funciones principales del intestino
    • las partes del intestino en el orden en que la comida pasa por ella

    Las células vegetales están hechas de moléculas orgánicas que utilizan la energía del sol. Este proceso se llama fotosíntesis. Los animales confían en estas moléculas orgánicas preparadas para suministrarles su alimento. Algunos animales (herbívoros) comen plantas; algunos (carnívoros) se comen a los herbívoros.
