Today, we're going to look at cycles, at phrasal verbs, and then we'll finish with a bit of
But now, here's a man who is a microbiologist and a mushroom grower.
He's talking about mushrooms, and the part they play in the carbon cycle.
They occur naturally in the forests as wood degrading fungi. That's their job. When trees
die, they grow on the tree. They break down the lignin and the cellulose, which is the
most resistant form of carbon, and they break it down, produce mushrooms and, in turn, you
end up with organic matter going back into the soil, and so the carbon cycle in the forest
The speaker, Noel Arrold, is talking about how mushrooms grow naturally.
They are an important part of the carbon cycle, but what is a cycle?
A cycle is a process that is repeated over and over. It goes around and around.
But how do we know this from listening to Noel?
