  2. Penjelasan • Rantai makanan adalah perpindahan energi makanan dari sumber daya tumbuhan melalui seri organisme atau melalui jenjang makan (tumbuhan – herbivora - carnivora - omnivora ) . Pada setiap tahap pemindahan energi , 80% - 90% energi potensial hilang serbagai panas, karena itu langkah – langkah dalam rantai makanan terbatas 4-5 saja. Dengan perekataan lain, semakin pendek rantai makanan semakin besar pula energi yang tersedia.

  3. Ada dua tipe dasar rantai makanan: 1. Rantai makanan rerumputan ( grazing food chain). Misalnya : tumbuhan – herbivora – carnivora - omnivora 2. Rantai makanan sisa ( detritus food chain ) . Bahan mati mikroorganisme (detritivora = organisme pemakan sisa) predator dan bangkai Para ilmuwan ekologi mengenal tiga macam rantai pokok yaitu rantai pemangsa, rantai parasit, dan rantai saprofit.
