Class 10 Environmental Management Worksheet
This Class 10 Science 2 Chapter 4 Environmental Management Worksheet is prepared according to the Maharashtra State Board Science and Technology Part 2 syllabus. It provides structured practice for unit tests, school examinations, preliminary examinations and the Maharashtra SSC Board examination.
The worksheet contains Maharashtra State Board exam important questions, MCQs, one-word answers, matching pairs, scientific reasons, short-answer questions, long-answer questions and situation-based activities. Selected previous board exam questions are included with their examination-year labels, making the worksheet useful as an SSC question bank.
Students revise ecosystems, food chains, food webs, biodiversity, threatened species, conservation methods, pollution control, environmental organisations and disaster management. The questions connect textbook concepts with familiar issues such as plastic waste, loss of forests, polluted water, wildlife protection, floods and emergency preparedness.

Ecosystem and Environmental Balance
An ecosystem includes living organisms and the non-living components of their surroundings. Plants, animals and microorganisms interact with air, water, soil, sunlight and temperature. These relationships allow energy to flow and nutrients to cycle through the environment.
Producers prepare food using solar energy. Consumers obtain energy by eating plants or other animals. Decomposers break down dead organisms and wastes, returning nutrients to the soil and water.
Food Chain and Food Web
A food chain shows one pathway of energy transfer. A food web contains several interconnected food chains. Food webs provide a more realistic picture because most organisms consume or are consumed by more than one species.
Biodiversity and Its Conservation
Biodiversity means the variety of living organisms, their genes and the ecosystems in which they live. Biodiversity supports ecological balance and provides food, medicines, raw materials, pollination, soil formation and climate regulation.
Threats to Biodiversity
- Destruction and fragmentation of natural habitats
- Pollution of air, water and soil
- Overexploitation of forests and wildlife
- Spread of invasive species
- Climate-related environmental changes
- Illegal hunting and wildlife trade
In-situ and Ex-situ Conservation
| Method | Meaning | Examples |
|---|---|---|
| In-situ conservation | Protecting organisms within their natural habitats | National parks, wildlife sanctuaries and biosphere reserves |
| Ex-situ conservation | Protecting organisms outside their natural habitats | Zoos, botanical gardens, seed banks and gene banks |
Pollution and Waste Management
Pollution is an undesirable change in the physical, chemical or biological quality of the environment. Pollutants can affect human health, wildlife, soil fertility, water quality and climate.
| Pollution | Common Cause | Control Measure |
|---|---|---|
| Air pollution | Vehicle exhaust and industrial emissions | Cleaner fuels, emission control and public transport |
| Water pollution | Untreated sewage and industrial waste | Treatment before discharge |
| Soil pollution | Plastic waste and excessive chemicals | Waste segregation and responsible chemical use |
| Noise pollution | Traffic, machinery and loud sound systems | Sound limits, maintenance and green buffers |
The Waste-Management Hierarchy
Individual and Community Responsibility
Environmental management requires participation from individuals, communities, organisations and governments. Individual actions become effective when they are continued consistently and supported by proper systems.
- Segregate wet, dry and hazardous waste
- Reduce unnecessary plastic consumption
- Conserve water and electricity
- Use public transport or shared transport where practical
- Protect local trees and water bodies
- Avoid disturbing wildlife and natural habitats
- Report illegal dumping or environmental damage
- Participate in community conservation programmes
Disaster Management
Disaster management is the organised process of reducing disaster risks and managing preparedness, response and recovery. A hazard becomes a disaster when it seriously disrupts a community and causes extensive loss that exceeds the community’s immediate capacity to cope.
Preparedness Measures
- Identify local hazards and safe locations
- Prepare emergency contact information
- Maintain a basic emergency kit
- Take part in school and community mock drills
- Follow instructions from authorised agencies
- Avoid spreading unverified information
- Provide first aid only within one’s training
Common Mistakes Students Should Avoid
- Confusing a food chain with a food web
- Drawing food-chain arrows in the wrong direction
- Writing biodiversity as only the number of animals
- Confusing in-situ and ex-situ conservation
- Listing pollution causes without explaining their effects
- Writing recycling as the first and only waste-management step
- Confusing a hazard with a disaster
- Giving disaster responses that may put students at further risk

What is environmental management?
Environmental management is the planned use, protection and restoration of natural resources. It includes conservation, pollution control, waste management and responsible development.
Why is biodiversity important?
Biodiversity supports food chains, pollination, nutrient cycling, soil formation and ecological stability. It also provides food, medicine and useful raw materials.
What is the difference between in-situ and ex-situ conservation?
In-situ conservation protects organisms in their natural habitats, such as wildlife sanctuaries. Ex-situ conservation protects them outside their natural habitats, such as in zoos, botanical gardens and seed banks.
Why is a food web more stable than a single food chain?
A food web provides alternative feeding pathways. If one food source decreases, some organisms may obtain energy from another source, reducing dependence on one pathway.
Why should waste be segregated?
Segregation keeps recyclable, biodegradable and hazardous wastes separate. This supports composting, recycling and safer disposal while reducing contamination.
What is the difference between a hazard and a disaster?
A hazard is a potentially damaging event or condition. It becomes a disaster when it causes serious disruption and losses beyond the affected community’s immediate capacity to manage.
How can students help protect the environment?
Students can reduce disposable plastic, conserve water and electricity, segregate waste, protect local biodiversity and participate responsibly in environmental activities.
