Biodegradable means 'degraded by natural bacteria'. This means that when a product is biodegradable it is eaten by natural bacteria faster than regular products.
Important!!!
Just because a product has biodegradable written on it does not mean that the product will degrade quickly. A brick is biodegradable but it will take years before it is fully broken down.
To make sure a product is really biodegradable look for the words 'readily biodegradable' on the product. These words give a guarantee that 70% or more of the product will biodegrade within 28 days.

The photos are a hint for you.
