    a diagram that shows feeding relationships and energy transfer

    Correct Answer
    Food Chain
    Explanation
    A food chain is a diagram that shows the feeding relationships and energy transfer between different organisms in an ecosystem. It illustrates how energy flows from one organism to another as they consume each other. The arrows in a food chain represent the direction of energy transfer, with the producers (plants) at the bottom, followed by the primary consumers (herbivores), secondary consumers (carnivores or omnivores), and finally the tertiary consumers (top predators). Each level of the food chain depends on the level below it for energy, making it an essential concept in understanding the balance and dynamics of ecosystems.

    When ecosystems tend to have only enough resources to support certain sizes of populations

    Correct Answer
    carrying capacity
    Explanation
    Carrying capacity refers to the maximum number of individuals that an ecosystem can sustainably support with its available resources. When an ecosystem has limited resources, such as food, water, or space, it can only support populations up to a certain size. This limit is known as the carrying capacity. When the population size exceeds the carrying capacity, there is a strain on the available resources, leading to competition, scarcity, and potentially population decline. Therefore, the concept of carrying capacity is relevant when ecosystems can only provide enough resources for specific population sizes.

    Increasing concentrations of harmful chemicals in organisms through a  food chain?

    Correct Answer
    Biological Magnification
    Explanation
    Biological magnification refers to the process in which harmful chemicals, such as pesticides or heavy metals, become more concentrated as they move up the food chain. This occurs because organisms at higher trophic levels consume a large number of organisms at lower trophic levels, resulting in the accumulation of these chemicals in their bodies. As a result, the concentration of these harmful chemicals increases as they move up the food chain, posing a greater risk to organisms at higher trophic levels, including humans.

    Rate this question:

  • 21. 

    A diagram that shows the amounts of energy or mass within each trophic level of a food chain?

    Correct Answer
    Ecological Pyramid
    Explanation
    An ecological pyramid is a diagram that represents the flow of energy or biomass through different trophic levels in a food chain. It shows the amounts of energy or mass present at each level, with producers at the bottom and top-level consumers at the top. This pyramid helps to visualize the decreasing amount of energy or biomass as it moves up the trophic levels, highlighting the concept of energy transfer and the dependence of higher-level organisms on lower-level organisms for energy.

    Rate this question:

    An organism that get its energy from breaking down organic matter?

    Correct Answer
    Detrivore
    Explanation
    A detrivore is an organism that obtains its energy by breaking down dead organic matter. This process of decomposition helps to recycle nutrients back into the ecosystem. Detrivores play an important role in the food chain by consuming decaying plant and animal material, such as dead leaves, carcasses, and feces. They break down these organic materials into simpler forms, releasing nutrients that can be used by other organisms. Examples of detrivores include earthworms, maggots, and certain types of bacteria and fungi.

    an autotroph that makes its own food by using energy from chemicals rather than sunlight

    Correct Answer
    Chemoautotroph
    Explanation
    A chemoautotroph is an organism that is able to produce its own food using energy derived from chemicals instead of sunlight. This process is known as chemosynthesis, where the organism utilizes inorganic compounds such as sulfur or iron to generate energy for the synthesis of organic molecules. Unlike phototrophs, which rely on sunlight for energy, chemoautotrophs can thrive in environments with little to no sunlight, such as deep-sea hydrothermal vents or caves. By harnessing the energy from chemical reactions, chemoautotrophs play a crucial role in various ecosystems by providing a source of energy for other organisms.
