When potassium is placed in water, it undergoes a highly exothermic reaction, producing hydrogen gas and forming potassium hydroxide (KOH) as a product. This reaction is also highly reactive and can result in the ignition of the hydrogen gas produced.
Fungi play a crucial role in nutrient cycling, breaking down organic matter and releasing nutrients back into the ecosystem. They also form mutualistic relationships with plants, aiding in nutrient uptake and enhancing plant resilience. Additionally, fungi contribute to the decomposition of dead organisms, helping to maintain ecosystem balance.
Compost consist of food scraps and other organic materials so f ungi feeds on the living or dead tissues of plants or animals. The fungi is already feeding on the leftovers, helping with the decomposistion, now it is releasing its spores from its fruiting body.
Pepsin, which is used to break down proteins, cannot work unless it is in an acid environment. Due to this fact, the stomach secretes both pepsin and hydrochloric acid to digest the protein in a meal.
