Final answer:
It is useful to know about the species of plants and animals in a defined area because it helps in understanding and conserving ecological communities. This knowledge assists in planning for conservation and sustainable development by identifying key species, prioritizing conservation efforts, and developing sustainable practices.
Step-by-step explanation:
Knowing about the species of plants and animals that live in a defined area, such as a park, county, or province, is useful for several reasons. First, it helps in understanding and conserving ecological communities. By studying the interactions between species and their environment, we can identify the key species and their roles in maintaining the balance of an ecosystem. This knowledge is crucial for planning conservation measures and sustainable development. For example, if we know that a certain plant species is important for the survival of an endangered butterfly, we can focus on protecting that plant and its habitat to ensure the butterfly's conservation.
Furthermore, understanding the species composition of an area provides valuable information for land use planning and resource management. It helps identify the areas of high biodiversity and prioritize them for conservation efforts. By considering the ecological needs and sensitivities of different species, we can develop sustainable development practices that minimize the negative impacts on the environment.
Overall, knowing about the species of plants and animals in a defined area is essential for understanding and conserving ecological communities, and it plays a crucial role in planning for conservation and sustainable development.
