(Originais Teachy 2023) - Question Easy of Sciences

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 observed fungi and bacteria play a fundamental role in the decomposition of leaves, releasing nutrients that were in the leaves back into the soil.

Leaf decomposition is a phenomenon that occurs exclusively through the action of larger animals inhabiting the forest, such as armadillos and wild boars.

Fungi and bacteria have no influence on the decomposition of leaves, which occurs only through physical processes such as the action of wind and water.

Although fungi and bacteria are present, the experiment suggests that larger and more complex plants also significantly contribute to the decomposition of leaves.

The role of fungi and bacteria in the decomposition of leaves is purely aesthetic, having no real impact on the release of nutrients to the soil.
