And then in later experiments, we found the opposite, that fir was sending more carbon to birch than birch was sending to fir, and this was because the fir was still growing while the birch was leafless.
Но в последующих экспериментах  я выяснила обратное. Пихта отправляла больше углерода берёзе, а не наоборот, ведь пихта ещё росла,  а берёза уже сбросила листву.
