What is the difference between photo degradable and biodegradable?
Photodegradable materials break down into smaller pieces when exposed to light, but may not fully decompose into natural elements. Biodegradable materials can be broken down by microorganisms into natural substances like water, carbon dioxide, and biomass. In summary, photodegradable materials break into smaller pieces under light exposure, while biodegradable materials break down into natural substances with the help of microorganisms.
How does the presence of water affect the decomposition of biodegradable materials?
Water helps to facilitate the decomposition of biodegradable materials by providing the necessary environment for microorganisms to break down organic matter. It also helps to regulate the temperature and oxygen levels necessary for decomposition. However, excessive water can slow down the decomposition process by limiting access to oxygen.
Is grass cuttings broken down by microorganisms?
yes it is not
Is fruit biodegrable?
Yes, fruits are biodegradable because they are organic materials that can naturally decompose. When disposed of, fruits will break down over time with the help of microorganisms and environmental factors, returning nutrients to the soil.
What causes dirt to stink?
Dirt can develop a foul odor due to the presence of decomposing organic matter, bacteria, and other microorganisms in the soil. These organic materials break down and release compounds like hydrogen sulfide, ammonia, and other volatile chemicals that contribute to the unpleasant smell.

What materials decompose the fastest?
Materials that decompose the fastest typically include food waste, paper products, and natural fibers such as cotton and wool. These materials break down more easily due to their organic composition and ability to be broken down by microorganisms in the environment.
What role do microorganisms play in the pond-life?
they break down the nitrates and nitrites in the water
What are the effects of micro-organisms on food?
Microorganisms help break down and decompose food. These microorganisms are what cause food to spoil and grow mold on it.
What happens to the energy from these materials as the decompose?
When materials decompose, the energy stored in the chemical bonds is released as heat. Microorganisms break down the materials through processes like fermentation or oxidation, converting the stored energy into a form that can be utilized by other organisms in the ecosystem.
What materials can decay easily?
Materials that can decay easily include organic matter such as food waste, paper, wood, and leaves. These materials break down quickly due to the presence of microorganisms that help in the decomposition process. Factors such as moisture, temperature, and oxygen levels can also affect the rate of decay for these materials.
Why do essential oils break down plastic materials?
Essential oils can break down plastic materials because they contain chemicals that can react with the polymers in plastics, causing them to degrade and break down over time.
Why are decomposers called decomposers?
To decompose means to break down. Decomposers break down organic materials.
What breaks down carbon in the environment?
Microorganisms, such as bacteria and fungi, break down carbon in the environment through a process called decomposition.
What is an example of beneficial effect of a microorganism?
Microorganisms help break down or digest the food we eat into nutrients.
Why does paper and cardboard decompose faster than plastic and glass?
Paper and cardboard are organic materials made from plant fibers, so they are biodegradable and break down naturally with the help of microorganisms. Plastic and glass, on the other hand, are synthetic materials that are not easily broken down by biological processes, leading to their slower decomposition rates.
Will the sun rot material?
The sun's ultraviolet (UV) radiation can cause materials such as plastics, fabrics, and some construction materials to degrade and weaken over time. This process is known as photodegradation, and it can cause materials to become brittle, discolored, or break down. However, the sun alone will not cause materials to rot in the same way that moisture and microorganisms can.
