Biodiversity refers to the variety of living organisms that inhabit a particular habitat. It is influenced by factors like topography, climate, and human activities. A biome is a large ecosystem characterized by its plant and animal life. There are two main categories of biomes - terrestrial biomes like forests, grasslands, deserts; and aquatic biomes. Each biome is defined by its geographic region, dominant vegetation, wildlife inhabitants, and how people occupy and utilize the area.
