It used as filling material for various walls such as partition walls inside your house, determines the maintenance of proper insulation. It is not an acidic material that will dissolve easily. It is used not just as wall-filling material but also for sealer and filling in furniture and carpets.
Answer:
The physical and chemical change that occurs in the aquaponics are given below.
Explanation:
The plants and animals grow in size and decrease the mass of plant due to eating by the fishes is a physical changes which occurs in aquaponics. The sunlight has a heat energy which is absorb by the plants present in aquaponics which is a type of endothermic reaction. In aquaponics, the ammonia present in water is converted into nitrates which is used by the plants as a nutrients. When the mass is converted into energy, it increases the temperature of the ecosystem and also the earth surface. For example, if a wood is burn, it change into heat energy which increases the temperature and cause the global warming on the earth surface.
