Understanding Ecosystems
An ecosystem includes living organisms and the non-living environment with which they interact.
🌿 Biotic Components
Plants
Animals
Fungi
Microorganisms
☀️ Abiotic Components
Sunlight
Water
Air
Soil and temperature
Examples of Ecosystems
Producers, Consumers and Decomposers
Organisms play different roles in ecosystems depending on how they obtain energy and nutrients.
Producers
Green plants and some other organisms produce organic food using energy, usually from sunlight.
Consumers
Consumers obtain energy by eating plants, animals or other organisms.
Decomposers
Many fungi and microorganisms break down dead organic material and help recycle nutrients.
Food Webs and Ecological Balance
Most organisms are connected through many feeding relationships. Several interconnected food chains form a food web.
Biodiversity and Its Importance
Biodiversity refers to the variety of life. It includes diversity within species, between species and among ecosystems.
Provide food, habitats and many useful materials.
Many flowering plants depend on animal pollinators.
Many microorganisms perform important ecological functions.
Different habitats support different communities of organisms.
Major Threats to Biodiversity
Plant Reproduction Through Seeds and Spores
Plants reproduce in different ways. Many flowering plants reproduce through seeds, while plants such as ferns and mosses reproduce using spores rather than seeds.
🌻 Seeds
Seeds contain an embryo that can develop into a new plant when conditions are suitable.
🌿 Spores
Spores are reproductive structures used by organisms including ferns, mosses and fungi.
They are generally much smaller and structurally simpler than seeds.
Special Adaptations for Extreme Environments
Extreme environments may be very hot, cold, dry, windy or otherwise challenging. Organisms living there possess adaptations that help them survive and reproduce.
| Environment | Organism | Example Adaptation |
|---|---|---|
| Desert | Cactus | Water-storing stem and reduced leaves |
| Desert | Camel | Several adaptations help conserve water and cope with heat |
| Arctic | Polar bear | Thick insulation reduces heat loss |
| High mountains | Some mountain animals | Features that help cope with cold and steep terrain |
| Salty coastal wetlands | Mangroves | Specialised adaptations to waterlogged, salty conditions |
Freshwater Resources and Their Management
Freshwater is essential for people, agriculture and ecosystems. Only a relatively small fraction of Earth’s total water is readily available freshwater.
Freshwater Sources
Responsible Water Management
Reduce unnecessary water use.
Capture rainwater where appropriate.
Prevent pollution of water sources.
Support groundwater recharge where possible.

Pollution
Construction and mining impacts
🌱 Protection
Maintain vegetation cover
Use suitable farming practices
Control erosion
Restore degraded land
Manage waste responsibly
Renewable and Non-Renewable Resources
Natural resources can be grouped according to how quickly natural processes replace them compared with the rate at which humans use them.
Renewable Resources
Can be replenished naturally on relatively short human timescales when appropriately managed.
- Sunlight
- Wind
- Flowing water
- Biomass when sustainably managed
Non-Renewable Resources
Exist in limited quantities or form so slowly that they are not replaced on human timescales.
- Coal
- Petroleum
- Natural gas
- Many mineral resources
Solar, Wind and Hydroelectric Energy
Renewable energy comes from sources that are naturally replenished. Solar, wind and flowing water can all be used to generate electricity.
Solar Energy
Solar panels can convert sunlight directly into electricity.

Wind turbines use moving air to generate electricity.
Hydroelectricity
Moving or falling water can turn turbines connected to generators.
Climate Change for Young Learners
Climate change refers to long-term changes in Earth’s climate. The rapid warming observed in recent times is mainly caused by human activities that increase greenhouse gases in the atmosphere, especially the burning of fossil fuels.
The Greenhouse Effect
Possible Effects of Climate Change
The Three Rs: Reduce, Reuse and Recycle
The Three Rs provide a simple way to think about reducing waste. Preventing unnecessary waste is generally better than dealing with waste after it has been created.
REDUCE
Use fewer unnecessary materials and avoid waste.
Example: Carry a reusable water bottle.REUSE
Use suitable items again instead of immediately discarding them.
Example: Reuse a durable container.RECYCLE
Process suitable discarded materials into new materials or products.
Follow local recycling rules.Waste Management and Composting
Waste management includes the collection, separation, treatment, recycling and safe disposal of waste.
Waste Segregation
Organic / Wet Waste
Food scraps and other suitable biodegradable materials.
Dry Recyclables
Suitable paper, metal, glass and plastics according to local rules.
Special Waste
Batteries, electronic waste, medicines and hazardous materials need appropriate collection systems.
Basic Composting Process
Wildlife Conservation and Protected Areas
Wildlife conservation aims to protect wild species, their habitats and the ecological processes on which they depend.
Protected Areas
Protected areas managed for conservation under applicable laws.
Areas designated for wildlife and habitat protection.
Large areas that can combine biodiversity conservation with sustainable use and research.
Examples in India
| Protected Area | State / Region |
|---|---|
| Jim Corbett National Park | Uttarakhand |
| Kaziranga National Park | Assam |
