When the leaves fall from the trees, they begin to decompose on the forest floor. This decomposition process is very important for nature, as it releases nutrients that were stored in the leaves back into the soil. Fungi and bacteria play a key role in this stage of the life cycle, acting as decomposers. An experiment was conducted in a forest area where leaves from different trees were collected. Each set of leaves was placed in a separate container and kept under suitable conditions to observe decomposition. The experiment lasted several weeks and the students regularly noted the changes that occurred. At the end of the experiment, they compared the decomposition state of each set of leaves. Based on the natural cycle, the importance of decomposition, and the described experiment, what conclusion can be drawn about the role of the fungi and bacteria observed in the decomposition of leaves in the forest?

The asthenosphere is an intermediate layer between the upper and lower mantle, responsible for the movements of tectonic plates due to its elasticity with high temperatures ranging from 700°C to 1,000°C. With which geological process is it related?

Ionic bonds are formed when atoms or groups of atoms transfer or share electrons, resulting in the stabilization of the system's energy by minimizing these forces between the particles involved in the chemical reaction. Which of these factors directly influence the process of ionic bonding?
