Answer:
Decomposers are organisms (mostly bacteria and fungi) that break down dead plants and animals, eventually turning them into nutrients that will be added to soil. These nutrients are very important to continue the cycle in the ecosystem. Slugs, earthworms, millipedes, and centipedes also help break down dead things.

The double fortification process involves adding iodine and iron to salt. It is a method used to fight micronutrient deficiencies in developing countries. Iron and iodine are two of the most important micronutrients involved in cognitive function, maternal and infant survival and human productivity. This is a cost-effective method that ensures that the population receives these nutrients without having to change their eating habits.
