    Study Notes

    Ecosystems

    • Ecosystems are made up of all the living organisms in a particular area interacting with each other and their non-living environment.
    • Living things like plants and animals make up the biotic components of an ecosystem.
    • The abiotic components of an ecosystem include non-living things like soil, air, water, and light.
    • The term 'ecosystem' comes from the Greek word 'oikos,' meaning 'house.'
    • Forests, ponds, and grasslands are all examples of ecosystems.
    • Sunlight is essential for all living organisms.
    • Green plants use sunlight to photosynthesize.
    • Animals either directly or indirectly rely on plants for food.
    • Water is an essential component of all living organisms and makes up approximately 60% of the human body.
    • Water is absorbed by plants through their roots.
    • Water acts as a medium for transport in the bodies of both plants and animals.
    • Temperature is a measure of warmth or coldness and is influenced by the sun's heat.
    • The Earth's temperature supports the growth and survival of living organisms.
    • The temperate deciduous forest has four distinct seasons – winter, spring, summer, and autumn.
    • Boreal forests, also known as taiga, are characterized by coniferous trees like pines, spruces, and larches.
    • Boreal forests have cold winters and warm summers and are often found near permanently frozen soil layers called permafrost.
    • Drainage is poor in boreal forests due to layers of rocks and permafrost.
    • The soil in boreal forests is acidic, mineral-poor and covered by a deep layer of rainfall.

    Flora and Fauna of Temperate Deciduous Forests

    • The temperate deciduous forest is home to a variety of flora and fauna.
    • Plants in the temperate deciduous forest have special adaptations to cope with the changing seasons.
    • Deciduous trees lose their leaves in the autumn and grow new leaves in the spring.
    • The temperate deciduous forest has a rich diversity of animal species, including the rat snake, lynx, and other wildlife.

    Flora and Fauna of Boreal Forests

    • Boreal forests have a characteristic flora, including coniferous trees, and a distinct fauna, like lynx.
    • The lynx, a mammal adapted to the cold climate, is a predator found in boreal forests.
