Ответ:

500000м квадратных

Объяснение:

Правило экологической пирамиды - закономерность, согласно которой количество растительного вещества, служащего основой цепи питания, примерно в 10 раз больше, чем масса растительноядных животных, и каждый последующий пищевой уровень также имеет массу, в 10 раз меньшую.

500*0,6=300кг – масса медведя (0,6 - это 60% воды)

белый медведь.300кг

тюлень 3000кг

рыба 30000кг

планктон 300000кг

600г=0,6кг

0,6кг – 1м

300000кг – х м

Где х площадь биоценоза

Х= 300000/0,6=500000м квадратных
