Learning time​

Kids learn by watching short, engaging video lessons.

Nature has its own way of recycling things, and it does it through organisms known as decomposers. Decomposers feed on things like animal remains, wood, fallen leaves from the trees, and even feces. If we didn't have decomposers, these things would pile up on the planet. Decomposers break these things down into smaller and simpler things that producers such as plants and algae can feed on. They add nutrients back into the soil and also back into water too. Decomposers include types of bacteria, types of fungi, and even types of insects known as detritivores. These include earthworms, termites, and even millipedes. Decomposers keep nutrients flowing.
