  • 2. 

    What is the process by which plants convert sunlight into energy? 

    • Respiration 

    • Photosynthesis 

    • Transpiration 

    • Decomposition

    Correct Answer
    A. Photosynthesis 
    Explanation
    Photosynthesis is like a plant's solar-powered food factory. Plants have a special pigment called chlorophyll that captures light energy. This energy is used to power a chemical reaction that combines carbon dioxide and water to produce glucose (a type of sugar). This glucose serves as the plant's primary source of energy for growth, reproduction, and other functions.

    Which type of organism breaks down dead matter and returns nutrients to the soil?

    • Producer 

    • Consumer 

    • Decomposer 

    • Herbivore

    Correct Answer
    A. Decomposer 
    Explanation
    Decomposers, such as bacteria and fungi, are essential for nutrient recycling in ecosystems. They act as nature's recyclers. When plants and animals die, decomposers break down their complex organic matter into simpler substances. This process releases essential nutrients like nitrogen and phosphorus back into the soil, where they can be absorbed and reused by plants.

    What is the role of bees in the environment? 

    • Pollination 

    • Decomposition

    • Seed dispersal 

    • Predation

    Correct Answer
    A. Pollination 
    Explanation
    Bees are vital pollinators, playing a crucial role in plant reproduction and food production. As bees fly from flower to flower collecting nectar, they inadvertently pick up pollen grains on their bodies. When they visit another flower, some of this pollen is transferred, fertilizing the plant. This fertilization process enables the plant to develop fruits and seeds, ensuring the continuation of its species.

  • 5. 

    What do animals release during respiration?

    • Oxygen 

    • Carbon dioxide 

    • Nitrogen 

    • Hydrogen

    Correct Answer
    A. Carbon dioxide 
    Explanation
    Respiration is the process by which animals convert the energy stored in food (glucose) into a form their cells can use. This process requires oxygen and produces carbon dioxide as a waste product. Animals breathe in oxygen and exhale carbon dioxide, which is then used by plants in photosynthesis.

  • 6. 

    What is the term for an animal that eats only plants? 

    • Carnivore

    • Herbivore 

    • Omnivore 

    • Detritivore

    Correct Answer
    A. Herbivore 
    Explanation
    Herbivores are animals that have adapted to a plant-based diet. They possess specialized digestive systems that can break down cellulose, the tough fibrous material found in plant cell walls. Herbivores play a crucial role in food chains by consuming plants (producers) and transferring energy to carnivores, which prey on them.

  • 7. 

    How do earthworms improve soil quality? 

    • Aeration, fertilization

    • Erosion, compaction 

    • Pollution, contamination 

    • Drying, depletion

    Correct Answer
    A. Aeration, fertilization
    Explanation
    Earthworms are nature's soil engineers, significantly improving soil health and fertility. As they burrow through the soil, they create channels that increase aeration, allowing for better water infiltration and oxygen circulation. Their digestive processes break down organic matter, and their castings (waste) act as a natural fertilizer, enriching the soil with nutrients.

    What is the role of vultures in the environment? 

    • Scavenging 

    • Pollination 

    • Seed dispersal 

    • Predation

    Correct Answer
    A. Scavenging 
    Explanation
    Vultures are nature's sanitation crew, playing a vital role in maintaining ecosystem health. They are scavengers that feed on the carcasses of dead animals. By consuming carrion, vultures prevent the spread of diseases that could arise from decaying flesh. They also help recycle nutrients back into the ecosystem.

  • 9. 

    What is the term for the natural home of a plant or animal? 

    • Ecosystem 

    • Habitat 

    • Community 

    • Niche

    Correct Answer
    A. Habitat 
    Explanation
    A habitat is the specific environment where an organism lives and finds the resources it needs to survive. It includes both living (biotic) and non-living (abiotic) components. For a plant, a habitat might be a forest floor with specific soil conditions and light levels. For a fish, it might be a coral reef with certain water temperature and salinity.

    Rate this question:

  • 10. 

    What is the term for a series of organisms each dependent on the next as a source of food?

    • Food chain 

    • Food web 

    • Ecosystem 

    • Community

    Correct Answer
    A. Food chain 
    Explanation
    A food chain is a linear sequence that shows how energy and nutrients flow through an ecosystem. It starts with producers (plants) that convert sunlight into energy. Herbivores consume plants, and then carnivores consume herbivores. Each organism in the chain represents a trophic level, and energy is transferred from one level to the next.
