- They break down waste, preventing excessive buildup and recycling nutrients. (correct)
- They consume waste to produce energy, leaving behind toxic byproducts.
- They transform waste into inert materials that have no environmental impact.
- They accelerate the accumulation of waste materials.

Study Notes
- If "bacteria" is the plural, the singular form for a single microbe of this kind is bacterium.
- Microbes break down and rot dead animal and plant material.
- Without microbes, we would be overwhelmed with waste.
- Nutrients in the soil, essential for plant growth and health, would not be replaced without microbes.
- Compost, beneficial for gardens, would not exist without microbes.
Compost Formation Experiment
- Collect a variety of objects to test their decay.
- Place the objects outside in a safe location.
- Observe the objects after a couple of weeks to see which have rotted the most.
- Do not handle the rotted material.
Bacteria Facts
- 500 bacteria could fit on a full stop.
- 160 billion bacteria would be needed to fill a teaspoon.
- Some bacteria can cause stone decay by producing acid.
- The acid produced by these bacteria dissolves the stone.
