    Which biome contains cactus and small bushes?

    • A.

      Tundra

    • B.

      Taiga

    • C.

      Desert

    • D.

      Grassland

    Correct Answer
    C. Desert
    Explanation
    Deserts are known for their extreme arid conditions and lack of rainfall. These conditions make it difficult for most plants to survive, but cacti and small bushes have adapted to store water and withstand the harsh environment. They have evolved to have thick stems or spines to reduce water loss and can survive in sandy or rocky soil. Therefore, the presence of cacti and small bushes is a characteristic feature of desert biomes.

    The base of any food chain or web is:

    • A.

      Small consumers

    • B.

      Producers

    • C.

      Predators

    • D.

      Prey

    Correct Answer
    B. Producers
    Explanation
    The base of any food chain or web is producers. Producers, such as plants and algae, are able to convert sunlight into energy through photosynthesis. They are the primary source of food and energy for all other organisms in the ecosystem. Without producers, there would be no energy available for consumers, predators, or prey, and the food chain/web would collapse.

    Rate this question:

  • 10. 

    The energy for producers is

    • A.

      Rain

    • B.

      Soil

    • C.

      Sun

    • D.

      Fertilizer

    Correct Answer
    C. Sun
    Explanation
    The correct answer is sun because producers, such as plants and algae, undergo photosynthesis to convert sunlight into energy. This process allows them to produce their own food and sustain themselves. Without sunlight, producers would not be able to carry out photosynthesis and obtain the energy needed for growth and survival.

    What does deciduous mean when we talk about trees?

    • A.

      The trees have needles

    • B.

      There are a lot of leaves on the trees

    • C.

      The leaves never fall off

    • D.

      The leaves fall off each fall and grow new ones in the spring

    Correct Answer
    D. The leaves fall off each fall and grow new ones in the spring
    Explanation
    Deciduous refers to trees that shed their leaves annually, typically in the fall season, and then regrow new leaves in the spring. This natural process allows deciduous trees to adapt to changing seasons and conserve energy during the colder months. Unlike evergreen trees, which retain their leaves year-round, deciduous trees experience a cycle of leaf loss and regrowth as part of their life cycle. This characteristic is a defining feature of deciduous trees.

    Bacteria and fungi have the role as

    • A.

      Producers

    • B.

      Consumers

    • C.

      Decomposers

    • D.

      Parasites

    Correct Answer
    C. Decomposers
    Explanation
    Bacteria and fungi have the role as decomposers because they break down dead organic matter and recycle nutrients back into the ecosystem. They play a crucial role in the decomposition process, breaking down complex organic compounds into simpler forms that can be used by other organisms. By decomposing dead plants and animals, bacteria and fungi help to release nutrients such as nitrogen, phosphorus, and carbon back into the soil, making them available for other organisms to use. Without decomposers, organic matter would accumulate and nutrients would be locked away, leading to a disruption in the nutrient cycle and ecosystem functioning.

    In this chart

    • A.

      There must be a number of predators since the number of prey is decreasing

    • B.

      The prey are not disappearing

    • C.

      There are the same number of predators and prey

    • D.

      There must be only a few predators since nothing is happening to the number of prey.

    Correct Answer
    A. There must be a number of predators since the number of prey is decreasing
    Explanation
    The correct answer suggests that there must be a number of predators since the number of prey is decreasing. This is because in a predator-prey relationship, as the number of predators increases, they consume more prey, leading to a decrease in the prey population. Therefore, the decrease in the number of prey indicates the presence of predators.
