  как мы видели, во всякой экосистеме необходимые для жизни вещества сохраняются сложным циклическим процессам, которые делают возможным многократное использование этих веществ. количество вещества ограничено, однако энергия практически неиссякаема. поэтому в отличие от замкнутого круговорота веществ поток энергии является однонаправленным, т. е. незамкнутым. количество энергии на любой стадии процесса можно оценить, если сжечь соответствующий материал в калориметре и измерить количество образовавшегося при этом тепла. изучение потока энергии позволяет получить дополнительные сведения о функциональной структуре биотических сообществ. кроме того, оно позволяет выяснить потенциальную биологическую продуктивность данного местообитания. располагая такими сведениями, можно вычислить, сколько особей каждого вида могло бы здесь существовать.
