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.
Em experiências posteriores, encontrámos o oposto, o abeto enviava mais carbono para a bétula do que a bétula enviava para o abeto, porque o abeto ainda estava a crescer, enquanto a bétula estava sem folhas.
