問題詳情：

Forest are amazing and so are the animals that live in them. We enjoy watching TV shows about bears, bats or monkeys. We know a lot about their lives: how they find food or what they do at different times of the year. But what about smaller animals that are more difficult to see or film?

Many small animals that live in forests are very important for the soil. A French scientist, Francois Xavier Joly, is studying one of them — the millipede(千足蟲).

The importance of leaves

When the leaves begin to die in fall, they turn from green to yellow and fall from the trees. As they decompose on the ground, nutrients(營養物質) are returned to the soil and carbon dioxide to the air. Life in the forest needs these nutrients. Without them, plants could not grow and there would be no food for animals such as the millipede.

Food on the forest floor

Some living things, like mushrooms, break the leaves into smaller pieces and eat them. In a few months there is nothing left of them. But for mushrooms, not all trees are the same. Mushrooms prefer some types of leaves to others. This means that some leaves take much longer to be broken down than others. Sometimes it takes years. So what happens to these? This is where the millipede can help.

More on the menu

The millipede also likes leaves and it eats any type. But when it has finished, it produces waste. This waste then becomes the food of mushrooms. When mushrooms eat leaves they choose only certain types but when they eat waste, they will eat any kind. This is how the millipede turns dead leaves into food for others and helps life continue.

So next time you are walking through a forest, remember that something may be having a meal right under your feet.
