Plants must have light in order to grow
所以它們為了得到充足的陽光
and will do anything to get as much as they need.
會各出奇招
The forest might appear to be the perfect place for plants to thrive.
森林似乎是 最適合植物生長的地方
Yet down here on the forest floor
但是對剛剛萌芽的新生植物來說
is one of the hardest places imaginable for a young plant to begin its life.
森林的地面是最難討生活的地方
The canopy above is so thick that only a little sunlight can filter through.
上方的樹冠層 濃密到只能透出一絲絲陽光
For this sapling, too little light means death.
這棵樹苗得不到足夠的陽光 只好黯然退出人生舞臺
But plants on the forest floor need not be passive.
但是地面上的植物 也可以主動出擊
If the light won't come to them, they can go to the light.
既然這里照不到光 就到有光的地方去
But they still have a problem.
但它們還是有一個問題
The light is 50 metres above them.
有光的地方離地面有五十公尺
So, they must climb.
它們只好往上爬
It's much easier to use another plant as scaffolding.
若能把其他植物當踏腳石 往上爬就輕松多了
