1Ecosystem
पारितंत्र
This Class 10 General Knowledge topic from Environment and Ecology explains how an ecosystem functions through interactions among living organisms and their surroundings. Students learn about biotic and abiotic components, food chains and food webs, energy flow, producers, consumers, and decomposers. The topic also introduces interdependence, ecological balance, habitats, and the effects of human activities, helping students understand how natural systems work and why conserving them is important.
0 questionsBiodiversity
जैव विविधता
This Class 10 General Knowledge topic introduces biodiversity as the variety of living organisms, genes, and ecosystems on Earth. Within the chapter Environment and Ecology, students learn how plants, animals, microorganisms, and habitats are interconnected, why biodiversity supports ecological balance and human life, and how activities such as habitat loss, pollution, overuse of resources, and climate change threaten it. The topic also explains conservation through protected areas, sustainable practices, and responsible community action.
7 questionsPollution
प्रदूषण
In this Class 10 General Knowledge topic from Environment and Ecology, students learn how pollution affects air, water, soil, and sound environments. They explore common sources such as vehicles, industries, household waste, chemicals, and excessive noise, along with their effects on human health, wildlife, biodiversity, and natural ecosystems. The topic also introduces practical measures for prevention and control, including waste reduction, recycling, clean energy, conservation, responsible consumption, and community participation.
18 questionsClimate Change
जलवायु परिवर्तन
This Class 10 General Knowledge topic, part of Environment and Ecology, introduces students to the long-term changes taking place in Earth’s climate. It explains the role of greenhouse gases, human activities such as burning fossil fuels and deforestation, and the effects on weather, ecosystems, agriculture, water resources, and human health. Students also explore climate change mitigation and adaptation, renewable energy, conservation, and responsible actions that can support a more sustainable future.
7 questionsConservation of Resources
संसाधनों का संरक्षण
Conservation of Resources is a Class 10 General Knowledge topic in the Environment and Ecology chapter. Students learn why natural resources such as water, forests, soil, minerals, and energy must be used carefully, how renewable and non-renewable resources differ, and how wasteful consumption affects ecosystems and future needs. The topic introduces practical approaches such as reducing use, reusing materials, recycling, protecting habitats, and supporting responsible choices by households and communities.
26 questionsWildlife Protection

In this Class 10 General Knowledge topic from Environment and Ecology, students learn why wildlife and biodiversity are essential for healthy ecosystems and human life. They explore major threats such as habitat loss, poaching, pollution, climate change, and illegal trade, along with conservation methods including national parks, wildlife sanctuaries, biosphere reserves, endangered-species protection, habitat restoration, and responsible resource use. The topic also highlights the role of laws, communities, and citizens in protecting animals, plants, and their natural habitats.
19 questionsRenewable Energy
नवीकरणीय ऊर्जा
In this Class 10 General Knowledge topic from Environment and Ecology, students learn how renewable energy comes from naturally replenished sources such as sunlight, wind, flowing water, biomass, and geothermal heat. The topic explains how solar panels, wind turbines, hydropower, and bioenergy work, and compares them with finite fossil fuels. Students also explore the role of clean energy in reducing pollution and greenhouse-gas emissions, conserving natural resources, supporting sustainable development, and addressing challenges such as storage, cost, and reliable supply.
4 questionsSustainable Development
सतत विकास
This Class 10 General Knowledge topic introduces Sustainable Development through the broader chapter Environment and Ecology. Students learn how present needs can be met without damaging the ability of future generations to meet theirs. It explains the balance among environmental protection, economic progress, and social well-being, along with ideas such as conserving natural resources, reducing pollution, protecting biodiversity, using energy responsibly, and managing waste. The topic also helps students connect everyday choices with long-term environmental responsibility.
