  • 2. 

    Carnivores are plant eaters.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    herbivores

    Rate this question:

  • 3. 

    Organisms that cannot make their own food are called consumers.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Consumers are organisms that rely on other organisms for their food. They cannot produce their own food through photosynthesis like plants do. Instead, they obtain energy by consuming other organisms. This can include animals that eat plants (herbivores), animals that eat other animals (carnivores), and animals that eat both plants and animals (omnivores). Therefore, the statement "Organisms that cannot make their own food are called consumers" is true.

    About 90% of the energy is lost (10% transferred) in a food chain from producer to consumer. - ProProfs

    About 90% of the energy is lost (10% transferred) in a food chain from producer to consumer.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    In a food chain, energy is transferred from one organism to another. However, not all of the energy is transferred efficiently. Only about 10% of the energy is passed from one trophic level to the next, while the remaining 90% is lost as heat or used by the organism for its own metabolic processes. This loss of energy occurs at each level of the food chain, resulting in a decrease in available energy for each successive consumer. Therefore, it is true that about 90% of the energy is lost in a food chain from producer to consumer.

    Plants use water and carbon dioxide to store the sun's energy.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Plants undergo a process called photosynthesis, where they use water and carbon dioxide in the presence of sunlight to produce glucose and oxygen. This glucose is then converted into other forms of energy, such as starch, which is stored in the plant's cells. Therefore, plants do use water and carbon dioxide to store the sun's energy, making the statement "True."

    The slug, snail, and mouse are primary consumers. - ProProfs

    The slug, snail, and mouse are primary consumers.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The statement is true because slugs, snails, and mice are all examples of primary consumers. Primary consumers are organisms that feed directly on producers, such as plants or algae. Slugs and snails are herbivores that eat plants, while mice are omnivores that eat both plants and other animals. Therefore, they all occupy the second trophic level in a food chain or food web, consuming producers and serving as a food source for secondary consumers.

    The snake and the hawk are primary consumers. - ProProfs

    The snake and the hawk are primary consumers.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    snake is secondary and hawk is tertiary

    Rate this question:

  • 8. 

    The amount of energy decreases for higher consumers.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    This statement is true because higher consumers require more energy to fulfill their needs, and as a result, the amount of energy available decreases. Higher consumers typically have a larger energy demand and consume more resources, leading to a decrease in the overall energy available.

    Rate this question:

  • 9. 

    Energy is transferred from the sun to consumers to producers.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    producers to consumers

    Rate this question:

  • 10. 

    Consumers that eat producers are called secondary consumers.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    primary
