    What is photosynthesis?

    It produces glucose and oxygen from carbon dioxide and water.

    Where does photosynthesis occur?

    In chloroplasts of plant cells.

    What are the raw materials needed for photosynthesis?

    Carbon dioxide, water, light energy, and chlorophyll.

    How do stomata function in photosynthesis?

    They allow gas exchange, letting CO₂ in and O₂ out.

    What is the main product of photosynthesis?

    Glucose, used for energy and growth.

    How does light intensity affect photosynthesis?

    Higher light intensity increases the rate, up to a point.

    What is the carbon cycle?

    It describes how carbon moves through the atmosphere and living organisms.

    What role do decomposers play in the carbon cycle?

    They break down dead organisms, returning carbon to the soil and atmosphere.

    What is the greenhouse effect?

    A natural process that keeps Earth warm by trapping heat.

    What human activity significantly contributes to climate change?

    Burning fossil fuels releases large amounts of carbon dioxide.

    How does deforestation impact the carbon cycle?

    It reduces carbon absorption and releases stored carbon.

    What are some effects of climate change?

    Rising temperatures, melting ice, and extreme weather events.

    How can renewable energy help reduce climate change?

    It produces little or no carbon dioxide emissions.

    What connects photosynthesis, the carbon cycle, and climate change?

    Photosynthesis removes CO₂, affecting the carbon cycle and climate.
