    The document provides an overview of ecosystems. It defines an ecosystem as a large community of living organisms in a particular area that interact with each other and their non-living environment. The key components of ecosystems are described as biotic factors like producers, consumers, and decomposers, as well as abiotic factors like climate and soil. Several types of natural ecosystems are outlined, including aquatic ecosystems like marine and freshwater, and terrestrial ecosystems like forests, deserts, grasslands, and mountains. The current threats facing ecosystems like climate change, pollution, overexploitation of resources are also summarized.

    ECOSYSTEM

    ECOSYSTEM
    • The term ecosystem was coined in 1935.
    • “Eco” comes from the word ecology which
    means anything having to do with environment.
    • “System” comes from the Greek word systema
    or “organised body, whole”
    WHAT IS A ECOSYSTEM?
    ❖An ecosystem is a large
    community of living
    organisms (plants, animals
    and microbes) in a particular
    area.
    ❖Ecosystems are of any size
    but usually they are in
    particular places.
    COMPONENTS OF ECOSYSTEM
    ECOSYSTEM

    BIOTIC ABIOTIC

    PRODUCERS CONSUMERS DECOMPOSERS

    PRIMARY SECONDARY TOP


    CONSUMERS CONSUMERS CONSUMERS
    BIOTIC COMPONENTS
    Biotic components can be
    described as any living
    component that affects
    another organism or shapes
    the ecosystem.
    This includes both animals
    that consume other organisms
    within their ecosystem.
    ABIOTIC COMPONENTS
    Abiotic components are
    non living chemical and
    physical parts of the
    environment that affect
    living organisms and the
    functioning of ecosystem.
    NATURAL ECOSYSTEM
    • Natural ecosystem is a
    community of living and non
    living organisms, where each
    component interacts together
    as a unit through biological,
    physical and chemical
    processes.
    • It consists of aquatic and
    terrestrial ecosystem.
    AQUATIC ECOSYSTEM
    • An aquatic ecosystem is a
    ecosystem in a body of water.
    • Communities of organisms
    are dependent on each other
    on their environment.
    • Aquatic ecosystems are of
    two types- marine ecosystem
    and freshwater ecosystem.
    MARINE ECOSYSTEM
    Marine ecosystem are
    the largest of earth’s
    aquatic ecosystems and
    are distinguished by
    waters that have high
    salt content.
    FRESHWATER ECOSYSTEM
    • Freshwater ecosystems are a
    subset of earth’s aquatic
    ecosystems.
    • They include lakes and
    ponds, rivers, streams,
    springs, bogs and wetlands.
    • They have low salt content.
    TERRESTRIAL ECOSYSTEM
    • Terrestrial ecosystem is a type of
    ecosystem found only on
    landforms.
    • A community of organisms and
    their environment that occurs on
    the land masses of continents and
    islands.
    • Example: Tundra, Tuforest,
    Tropical rainforest, Grassland and
    deserts.
    FOREST ECOSYSTEM
    A forest ecosystem is a natural
    woodland unit consisting of all
    plants, animals and micro-
    organisms(biotic
    components)in that area
    functioning together with all of
    the non living physical
    (abiotic) factors of the
    environment.
    DESERT ECOSYSTEM
    • A desert ecosystem is
    defined by interactions
    between organism
    populations , the climate
    in which they live, and
    any other non living
    influences on the habitat.
    GRASSLAND ECOSYSTEM
    • Grasslands are areas where the
    vegetation is dominated by
    grasses; however, sedge and rush
    families can also be found along
    with variable proportions of
    legumes, like clover, and other
    herbs.
    • Grasslands naturally occur on all
    continents except Antarctica.
    MOUNTAIN ECOSYSTEM
    • Mountain ecosystem
    refers to any ecosystem
    found in mountains.
    • These ecosystems are
    strongly affected by
    climate, which gets colder
    as elevation increases.
    CURRENT ECOSYSTEM
    • Current position of ecosystem has
    become worse due climate change and
    natural calamities as recently floods
    which took place in many states,
    drought, mining, overexploitation in
    fishing, farming, chemical spills.
    • The major reason behind ecosystem
    being destroyed is pollution in the
    environment may it be water pollution
    which damages aquatic ecosystem or air
    pollution that damages terrestrial
    ecosystem.
    When you saves water,
    it saves you back,
    When you refuse to
    reuse,
    It’s the earth you abuse
    Save the ecosystem,
    We have nowhere else
    to go
