Habitat structure refers to the physical arrangement of different elements within an environment where organisms live. This includes features like trees, rocks, water bodies, and soil types, which create various niches for plants and animals. The complexity of habitat structure can influence biodiversity, as it provides shelter, food, and breeding sites for different species. Different habitats, such as forests, wetlands, and grasslands, have unique structures that support specific communities of organisms. For example, in a forest, the vertical layers created by canopy, understory, and forest floor offer diverse living conditions. This complexity helps maintain ecological balance and supports various life forms.
