Some Unique Places - Ecotourism and Conservation

Grade 5CBSE

Review the key concepts, formulae, and examples before starting your quiz.

🔑Concepts

•

Ecotourism is responsible travel to natural areas that conserves the environment and sustains the well-being of local people. It emphasizes on education and low environmentalenvironmental impact.

•

Biodiversity refers to the variety of plant and animal life in a particular habitat. High biodiversitybiodiversity is a sign of a healthy ecosystem.

•

National Parks are strictly protected areas where human activities like hunting, grazing, or cultivation are prohibited to protect wildlife and their natural habitat. Examples include Jim Corbett and Kaziranga.

•

Wildlife Sanctuaries are areas where certain human activities are allowed but the main goal is to protect a specific species of flora or fauna.

•

Biosphere Reserves are large areas of protected land meant for the conservation of biodiversitybiodiversity and the traditional lifestyles of the tribal people living there.

•

Conservation is the wise use and protection of natural resources. The 3R's of conservation are: ReduceReduce, ReuseReuse, and RecycleRecycle.

•

Project Tiger was launched in India in 19731973 to ensure a viable population of Bengal tigers in their natural habitats.

•

Unique ecosystems include the Sundarbans (the world's largest mangrovemangrove forest) and the Western Ghats (a global biodiversitybiodiversity hotspot).

📐Formulae

Net Population=Initial Population+Births−Deaths\text{Net Population} = \text{Initial Population} + \text{Births} - \text{Deaths}

Population Density=Total Number of AnimalsTotal Area (sq. km)\text{Population Density} = \frac{\text{Total Number of Animals}}{\text{Total Area (sq. km)}}

Recycling Rate (%)=(Weight of Recycled WasteTotal Waste Weight)×100\text{Recycling Rate (\%)} = \left( \frac{\text{Weight of Recycled Waste}}{\text{Total Waste Weight}} \right) \times 100

💡Examples

Problem 1:

In a specific sector of the Gir National Park, there were 245245 Asiatic lions. Over a year, 1818 cubs were born and 77 lions died due to natural causes. Calculate the final number of lions using vertical arithmetic.

Solution:

245+18263−7256\begin{array}{r} 245 \\ + 18 \\ \hline 263 \\ - 7 \\ \hline 256 \end{array}

Explanation:

To find the new population, we add the number of births to the initial count and then subtract the number of deaths.

Problem 2:

A forest reserve has an area of 500 km2500\ km^2. If there are 25002500 deer in this reserve, what is the population density of deer per km2km^2?

Solution:

Density=2500500=5 deer per km2\text{Density} = \frac{2500}{500} = 5\ \text{deer per } km^2

Explanation:

Population density is calculated by dividing the total number of individuals by the total area of the habitat.

Problem 3:

During an ecotourism drive, a group collected 800 kg800\ kg of waste. If 600 kg600\ kg of this waste was biodegradable and sent for composting, how much non-biodegradable waste was left?

Solution:

800−600200\begin{array}{r} 800 \\ - 600 \\ \hline 200 \end{array}

Explanation:

Subtracting the biodegradable waste from the total waste gives the amount of non-biodegradable waste (200 kg200\ kg) that needs different disposal methods.
