There are thought to be nearly a million different types of fungi in the tropics,
the vast majority still unknown to science.
But one thing's for certain. Without fungi, rainforests could not exist.
Nothing goes to waste in a rainforest.
The fungi become food for others, like these beetle larvae.
Finding the fungus isn't a problem for the grubs since their caring parents actually show them the way.
Incredibly, 80% of all insects live in jungles.
Few are more successful than the ants.
There can be eight million individuals in a single hectare.
But jungle ants don't have it all their own way.
