The correct answer is A. Uppermost level of the forest.
The canopy is the uppermost layer of a forest, formed by the crowns of trees. It is the most important layer of the forest, as it provides habitat for many different animals and plants, and it helps to regulate the climate of the forest.
The ground level of the forest is the layer of soil and vegetation that is directly below the canopy. It is home to a variety of plants and animals, including many that are adapted to living in shady conditions.
The soil in a forest is the layer of loose material that covers the bedrock. It is made up of a mixture of minerals, organic matter, and water. The soil in a forest is important for supporting the growth of plants, and it also helps to regulate the water cycle.
Climbers on trees are plants that grow up the trunks and branches of trees. They use their roots or tendrils to attach themselves to the trees, and they often have leaves that are adapted to living in shady conditions.
