Biodegradable means it can be decomposed but it needs a chemical agent to help break it down . Whereas degradable means it can be chemically degraded and it does not need an agent to degrade it.
All material that we have no further use for can be called waste,this can be differentiated into two categories,biodegradable & non biodegradable/The first is all material like,paper,garden waste & lawn clippimgs,non greasy food, cloth scraps,wood shavings,material from cleaning up pet cages etc,these can be broken down by insects worms & other soil organisms into humus which can safely be part of the soil,composting is a good example of converting biodegradables into a useful end product.Non biodegradables reguire recycling depending on the material.The important lesson is the concept that we are responsible for the safe & sensible disposal of items we no longer have use for disposing items
Persistent pollutants remain in the environment for long periods of time without breaking down, while biodegradable pollutants can be broken down by natural processes into simpler, non-harmful substances over time. Persistent pollutants can accumulate in organisms and ecosystems, causing long-term harm, whereas biodegradable pollutants are less harmful as they can be naturally degraded.
Nothing.
Biodegradable can be broken down by the earth naturally, non- biodegradable can not.
Primary pollutants are pollutants that enters the air directly from a source and Secondary pollutants are air pollutantsproduced by the reaction of a primary pollutant with some other pollutant
Biodegradable means that something is capable of being decomposed by bacteria or other living organisms. A paper wrapper for a sandwich is biodegradable, but a plastic box is not. Bury the plastic box, dig it up a year later, it is still there. The paper wrapper would have degraded to humus (soil).
Material that's nonliving (excluding dead organic matter) is non-biodegradable. Plastic, metal, styrofoam, and corrugated cardboard are non-biodegradable, while a dead tree, animal waste, and skin cells are biodegradable. A difference between biodegradable trash and non-biodegradable trash is that the biodegradable can be thrown out into a backyard and eventually turn into soil or something that other living things can reuse, while non-biodegradable trash can be recycled, as in reused for its original purposed, usually for humans.
Dioxin's are pollutants formed when waste is not incinerated at high enough temperatures. A Dachshund is a dog.
When something is bio degradable it will break down in the environment with the assistance of bacteria or other organisms. Non bio degradable detergent will not break down naturally without chemical assistance.
Some Primary pollutants are like when humans directly put them in the air Secondary pollutants are like when pollutants react with Primary and other Primary pollutants.
Biodegradable polythene is designed to break down naturally into non-toxic materials, while ordinary polythene does not easily decompose and can persist in the environment for a long time. Biodegradable polythene is more environmentally friendly as it reduces waste and pollution.
Only Plastics are non biodegradable. because the molecular bond between them is so strong hence it is difficult to break it hence it is non 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.
