1. why do people in their communities recycle paper, glass, aluminum and other materials?
2. how organisms in the environment use the suns energy?
3. what materials can usually be recycled, and why is it important to separate them correctly?
4. what is one way people can improve recycling in their homes or communities?
5. how does recycling help reduce the amount of waste in landfills and protect the environment?
6. why is water essential for life?
7. why cant you live without carbon?
8. why is nitrogen essential for life?
9. what are the three physical forms of water?
10. what is the difference between evaporation, condensation, precipitation and transpiration?
11. why do plants need water?
12. how can human activities, like urban development, affect the natural flow of the cycle?

Explanation:

1. Recycling conserves resources, reduces waste in landfills, and saves energy.
2. Organisms use solar - energy mainly through photosynthesis in plants to make food.
3. Common recyclables include paper, plastic, glass, and metal. Separation is crucial for efficient recycling processes.
4. One way to improve recycling is by educating community members about proper recycling practices.
5. Recycling reduces landfill waste by reusing materials instead of sending them to landfills and conserves natural resources, protecting the environment.
6. Water is essential for life as it is involved in many biological processes like digestion, circulation, and cell function.
7. Carbon is a key element in organic compounds that make up living organisms, such as carbohydrates, proteins, lipids, and nucleic acids.
8. Nitrogen is essential for life as it is a component of amino acids (building blocks of proteins) and nucleic acids (DNA and RNA).
9. The three physical forms of water are solid (ice), liquid (water), and gas (water vapor).
10. Evaporation is the change of liquid water to water vapor; condensation is the change of water vapor to liquid water; precipitation is water falling from the atmosphere as rain, snow, etc.; transpiration is the loss of water vapor from plants.
11. Plants need water for photosynthesis, nutrient transport, and to maintain turgor pressure for structural support.
12. Human activities like urban development can change the water - cycle by reducing infiltration (e.g., through pavement), increasing runoff, and altering evaporation rates.

Answer:

1. Recycling conserves resources, reduces waste, and saves energy.
2. Through photosynthesis in plants to make food.
3. Common recyclables: paper, plastic, glass, metal. Separation for efficient recycling.
4. Educate community members about proper recycling.
5. Reuses materials instead of sending them to landfills and conserves resources.
6. Involved in many biological processes like digestion and cell function.
7. Key element in organic compounds of living organisms.
8. Component of amino acids and nucleic acids.
9. Solid (ice), liquid (water), gas (water vapor).
10. Evaporation: liquid to vapor; Condensation: vapor to liquid; Precipitation: water falling; Transpiration: plant water - vapor loss.
11. For photosynthesis, nutrient transport, and structural support.
12. Can reduce infiltration, increase runoff, and alter evaporation rates.
