Ответы (примерные образцы)

1. Пример ответа: An ecosystem is a community of living things (plants, animals, microorganisms) that interact with each other and with their non-living surroundings (air, water, soil). Energy flows through the system and matter cycles within it, keeping everything alive and functioning.

2. Пример ответа:

• Renewable energy sources: solar and wind. Non-renewable: coal and oil.
• Advantages of renewables: they produce less pollution and are sustainable in the long term. Disadvantages: they can be intermittent (sun and wind are not always available) and require investment in infrastructure.
• Advantages of non-renewables: they provide reliable, inexpensive energy and power many technologies today. Disadvantages: they pollute the air and soil and will eventually run out.

3. Пример ответа: Photosynthesis is the process by which plants use sunlight to make food. In the chloroplasts, plants take in water from the soil and carbon dioxide from the air. With light energy, they convert these ingredients into glucose (a sugar) and release oxygen as a byproduct. The overall gist is that light energy is transformed into chemical energy stored in glucose.

4. Пример ответа:

• Biodiversity provides food security and medicines; a wide variety of species can be sources for crops and drugs (e.g., pollinators help crops grow).
• It also makes ecosystems more resilient to changes (variations in climate, disease) because a variety of species can compensate for losses.

5. Пример ответа:

• Use reusable bags and bottles instead of single-use plastics.
• Avoid products with excess plastic packaging and choose items in glass/metal packaging.
• Recycle plastics correctly and participate in local clean-up efforts.

6. Пример ответа: Air pollution harms human health by causing respiratory diseases, asthma, and heart problems. It also affects the environment by creating smog, acid rain, and harming animals and plants. Long-term exposure can contribute to climate change and reduce life quality for many living beings.

7. Пример ответа:

• Differences: urban areas have more buildings, roads, and pollution; rural areas have more open space, wildlife, and agricultural land.
• Challenges: in cities, air and noise pollution and heat islands are common; in rural areas, habitat fragmentation and water pollution from farming can be problems. Both need conservation efforts and clean energy solutions.

8. Пример ответов (5 sentences):

• My local park is an urban habitat with trees, grass, and a small pond.
• The park provides a habitat for producers like grasses and algae and for consumers such as insects, birds, and small mammals.
• The beech trees and grasses are producers, while insects and birds are consumers.
• Decomposers like fungi and bacteria break down fallen leaves and dead plants.
• People can protect it by keeping it clean, recycling, and avoiding littering.

9. Пример ответа:

• Food chain: sunlight → grass (producer) → grasshopper (primary consumer) → frog (secondary consumer) → snake (tertiary consumer).
• Food web: in a pond, algae (producer) feed many organisms; insects eat algae; fish eat insects; birds eat fish; decomposers break down leftovers, all connected in a network rather than a single path.

10. Пример ответа: Saving water is important because it preserves freshwater for people and ecosystems. Actions: take shorter showers, fix leaks, run full loads in dishwashers and washing machines, turn off taps while brushing teeth, collect rainwater for plants. Benefits: lowers water bills and reduces energy use for heating water, helping the environment.

11. Пример ответа:

• Replace incandescent bulbs with LED lights.
• Turn off lights and electronics when not in use.
• Use a programmable thermostat and set reasonable temperatures.
• Improve insulation and seal leaks in doors/windows.
• Prefer energy-efficient appliances and wash clothes at full loads. Impact: reduces energy consumption, lowers greenhouse gas emissions, saves money.

12. Пример ответа (диалог): Учитель: “Why do you think littering is bad for the campus?” Ученик: “Litter can harm animals, clog drains, and make the place look dirty.” Учитель: “What can students do instead?” Ученик: “We can use recycling bins, pick up litter, and encourage others to dispose of waste properly.”

13. Пример перевода: Waste management is an important part of protecting nature.

14. Пример ответа: Bees pollinate many crops and wild plants, helping ecosystems produce fruits, seeds, and biodiversity. Without bees, crop yields could decline, plant communities could suffer, and animals relying on those plants might lose food and habitat. Their decline would disrupt food webs and ecosystem services like pollination and biodiversity maintenance.

15. Пример ответа: I partly disagree with the statement. Technology is a powerful tool and can help solve many ecological problems (e.g., clean energy tech, waste management, monitoring ecosystems), but it cannot solve everything by itself. We also need changes in behavior, policy, conservation, and responsible consumption. Technology must be combined with sustainable practices, education, and good governance to be truly effective.
