The correct Answer is:
To solve the question, "A unit of land delimited by natural boundary and having patches of different biotic communities is," we can follow these steps: ### Step 1: Understand the Terms - **Ecosystem**: This is a biological community of interacting organisms and their physical environment. It includes various biotic (living) and abiotic (non-living) components. - **Landscape**: This refers to a heterogeneous area that consists of different ecosystems or biotic communities. Landscapes are often defined by natural boundaries and can contain various patches of different communities. - **Biome**: This is a larger ecological unit that encompasses multiple ecosystems and is characterized by specific climate conditions and types of organisms. ### Step 2: Analyze the Options - **Option A (Ecosystem)**: This does not fit the description as ecosystems do not necessarily have natural boundaries or patches of different communities. - **Option B (Landscape)**: This fits well since a landscape is defined as a unit of land with different biotic communities and can be delimited by natural boundaries. - **Option C (Biome)**: This is too large of a unit and does not specifically refer to patches of different communities within a defined area. - **Option D (Both B and C)**: This cannot be correct since only one option fits the description accurately. ### Step 3: Conclusion Based on the definitions and analysis of the options, the correct answer is **Option B: Landscape**. ### Final Answer: **B. Landscape** ---

The Class X students of a secondary school in Krishinagar have been allotted a rectangular plot of land for their gardening activity. Sapling of Gulmohar are planted on the boundary at a distance of 1 m from each other. There is a triangular grassy lawn in the plot as shown in the Figure. The students are to sow seeds of flowering plants on the remaining area of the plot. (i) Taking A as origin, find the coordinates of the vertices of the triangle. (ii) What will be the coordinates of the vertices of DPQR if C is the origin? Also calculate the areas of the triangles in these cases. What do you observe?
