Materials cycle through ecosystems as elements from the environment form compounds in living things, are transferred through the food chain, and are recycled back into the environment upon death.
Como os materiais ciclam através das partes bióticas e abióticas de um ecossistema? Seres vivos são feitos de elementos do ambiente, que se transformam em compostos complexos como proteínas e gorduras. Quando os animais se comem, eles são passados adiante. Quando morrem, os elementos são reciclados e devolvidos ao solo ou ar.

| Back | Living things are made of elements from the environment, which turn into complex compounds such as protein and fats. When animals eat each other, they are passed along. When they die, the elements are recycled and returned into the soil or air. |
