Which of the following protected area cover both land and water ecosystems?Options :National ParksBiosphere reserveWildlife sanctuariesBotanical garden

To determine which of the options cover both land and water ecosystems, we need to analyze each option individually.

1. National Parks: National Parks are typically designated to protect and preserve natural areas of land. While some national parks may have bodies of water within their boundaries, they primarily focus on land ecosystems. Therefore, national parks may not cover both land and water ecosystems.

2. Biosphere Reserves: Biosphere reserves are areas that aim to conserve biodiversity while promoting sustainable development. These reserves often encompass a variety of ecosystems, including both land and water ecosystems. Therefore, biosphere reserves can cover both land and water ecosystems.

3. Wildlife Sanctuaries: Wildlife sanctuaries are designated areas that provide protection and conservation for wildlife species. While some wildlife sanctuaries may have water bodies within their boundaries, they primarily focus on land ecosystems and the preservation of wildlife habitats. Therefore, wildlife sanctuaries may not cover both land and water ecosystems.

4. Botanical Gardens: Botanical gardens are designed for the cultivation and display of a wide variety of plant species. While botanical gardens may have water features such as ponds or streams, their primary focus is on land-based plant ecosystems. Therefore, botanical gardens may not cover both land and water ecosystems.

Based on the analysis, the option that covers both land and water ecosystems is Biosphere Reserves.
