IntroductionThe task we were given was to start off with an ecosystem that was stable and then make changes to the ecosystem in ways that will make the ecosystem unstable or make it more stable and better The grass was left to grow for a week, and after, we conducted different experiments to find out which substances affected ecojar growth in a good way or in a bad way.
Background:Fertilizer is a compound that is given to plants to encourage growth. The fertilizer used In the experiment was all-purpose fertilizer, which meant that it could be used on any type of plants. All-purpose fertilizers are mostly applied in the soil for uptake by plant roots or by the process of foliar feeding, for uptake through leaves. Fertilizer that is put into the soil for uptake by plant roots is more commonly used because all the nutrients go straight to the roots of the plant.
Fertilizers can be composed of organic matter or be made of inorganic chemicals or minerals. The reason why fertilizers are used is because they provide plants with a boost of the nutrients they need for growth. Fertilizers provide the three major plant nutrients: Nitrogen, Phosphorous and Potassium. Without nitrogen, phosphorus and potassium, the plant cannot grow because it cannot make the pieces it needs. Fertilizer has to be mixed with a lot of water because it dissolves it, and without water, the fertilizer nutrients would be too big to pass into the roots.
Laundry Detergent is a substance used to remove dirt and foreign matter of contaminated surfaces or fabrics. Detergents act upon a surface, and the ones that are made for use with water often include compounds such as:Abrasive to scourEnzymes to digest or process proteins and fats in stainsSurfactants to ÃÂcutÃÂ grease in surfacesWater...
