¿QUÉ SON LAS REDES Y CADENAS ALIMENTARIAS?
Kalman B.
Ilustrado con muchas fotografías y dibujos en color, enseña a los más jóvenes qué son las cadenas alimentarias. Comenta la energía contenida en los alimentos, las plantas como productoras, el papel de herbívoros y carnívoros, los descomponedores, y ejemplos de redes alimentarias en distintos biomas.
