    Study Notes

    Plant Structure and Function

    • Xylem tissues carry water from the roots through the stem.
    • Phloem tissues do not carry water from the roots through the stem.

    Ecosystems and Producers

    • Grass is an example of a producer in an ecosystem.
    • Producers make their own food through photosynthesis.

    Stomata Function

    • Stomata are responsible for carrying out gas exchange in plants.

    Invasive Species

    • Invasive species are not native to an ecosystem.
    • Invasive species can harm the environment, spread quickly, and damage the economy and human health.

    Niche and Habitat

    • An earthworm's niche is breaking down plant matter in the soil.
    • Habitat refers to the natural environment in which an organism lives.

    Plant Leaves and Nutrients

    • Leaves take in sunlight and carbon dioxide to obtain nutrients for the plant's survival.
    • Leaves do not take in water and give off carbon dioxide.

    Plant Growth Conditions

    • Plants need soil and water to grow and survive.
    • Plants can be affected differently by various growing conditions.

    Hydrosphere Interaction

    • Interacting with the hydrosphere can be done through activities like swimming.

    Ecosystem Matter Transfer

    • Matter transfers among organisms and the ecosystem.

    Food Chain and Predation

    • Prey refers to organisms that are eaten by other animals.
    • Herbivores, carnivores, and predators have distinct roles in the food chain.

    Decomposers and Ecosystem Balance

    • Decomposers break down plant and animal matter, maintaining ecosystem balance.
    • Decomposers enrich the soil, helping plants grow.

    Earth's Systems

    • The geosphere, hydrosphere, atmosphere, and biosphere are interconnected Earth systems.
    • Rivers are part of the hydrosphere, not the geosphere.

    Desert Ecosystem Interactions

    • In a desert ecosystem, the geosphere and hydrosphere interact with each other.

    Water Cycle

    • Condensation is the process of water vapor changing to a liquid.
