Rantai Makanan BY:AMRUL
Mengenal Rantai Makanan • Rantai makanan adalah perpindahan energi makanan dari sumber daya tumbuhan melalui seri organisme atau melalui jenjang makan (tumbuhan – herbifora – carnivora – omnivora). Pada setiap tahap pemindahan energi, 80%-90% energi potensial hilang sebagai panas, karena itu langkah-langkah dalam rantai makanan terbatas 4-5 langkah saja. Dengan perkataan lain, semakin pendek rantai makanan semakin besar pula energi yang tersedia.
