    Study Notes

    Ecosystems Overview

    • Ecosystems consist of all living organisms (plants, animals, microorganisms, humans) interacting with each other and their physical environment (air, water, soil).
    • Defined as the system where living organisms engage with non-living components to maintain nature's balance.
    • Rely on sunlight for energy, captured by green plants to produce food, forming the base of the food chain.
    • Without energy, ecosystems cannot function effectively.

    Habitat Types

    • Ecosystems can be found in natural settings or managed artificially by humans.

    Components of Ecosystems

    • Abiotic (Non-living) Components:

      • Inorganic substances like carbon dioxide, oxygen, nitrogen, water, and minerals.
      • Organic compounds (proteins, carbohydrates, fats) connect abiotic and biotic components.
      • Climatic factors classified into atmospheric (temperature, light, humidity, wind, rainfall) and edaphic (soil-related) factors.

    • Biotic (Living) Components:

      • Comprised of diverse living organisms organized into interdependent populations.
      • Removal of a single species can disrupt ecological balance.

    Modes of Nutrition in Biotic Components

    • Autotrophs (Producers):

      • Organisms that synthesize their own food through photosynthesis, like green plants.
      • Convert solar energy into chemical energy.

    • Heterotrophs (Consumers):

      • Organisms dependent on others for food, including humans and animals.
      • Classified into:
        • Primary Consumers (Herbivores): Directly consume producers (e.g., cattle, sheep, deer).
        • Secondary Consumers (Carnivores): Feed on primary consumers (e.g., lion, tiger).
        • Tertiary Consumers: Feed on secondary consumers; top carnivores that are not preyed upon (e.g., leopard, tiger).

    • Decomposers (Saprophytes):

      • Organisms (like bacteria and fungi) that break down dead organic matter, replenishing nutrients in soil.
      • Play a critical role in maintaining soil fertility and nutrient cycling.

    • Scavengers:

      • Animals that consume dead animals (e.g., hawk, crow, vulture).

    Interdependence in Ecosystems

    • All living organisms rely on one another for survival, creating a complex web of dependencies.
    • Examples:
      • Deer depend on grass directly for food; lions depend on deer indirectly.
    • Maintaining balanced populations is crucial; too many predators can drive prey to extinction, and vice versa.

    Importance of Ecological Balance

    • A delicate balance exists between living organisms and their environment, vulnerable to disruption by human activities.
    • Preserving this balance is essential for ecosystem health and sustainability.

        • Tertiary Consumers: Feed on secondary consumers; top carnivores that are not preyed upon (e.g., leopard, tiger).

    • Decomposers (Saprophytes):

      • Organisms (like bacteria and fungi) that break down dead organic matter, replenishing nutrients in soil.
      • Play a critical role in maintaining soil fertility and nutrient cycling.

    • Scavengers:

      • Animals that consume dead animals (e.g., hawk, crow, vulture).

    Interdependence in Ecosystems

    • All living organisms rely on one another for survival, creating a complex web of dependencies.
    • Examples:
      • Deer depend on grass directly for food; lions depend on deer indirectly.
    • Maintaining balanced populations is crucial; too many predators can drive prey to extinction, and vice versa.

    Importance of Ecological Balance

    • A delicate balance exists between living organisms and their environment, vulnerable to disruption by human activities.
    • Preserving this balance is essential for ecosystem health and sustainability.

    Ecosystems Overview

    • Ecosystems consist of all living organisms (plants, animals, microorganisms, humans) interacting with each other and their physical environment (air, water, soil).
    • Defined as the system where living organisms engage with non-living components to maintain nature's balance.
    • Rely on sunlight for energy, captured by green plants to produce food, forming the base of the food chain.
    • Without energy, ecosystems cannot function effectively.

    Habitat Types

    • Ecosystems can be found in natural settings or managed artificially by humans.

    Components of Ecosystems

    • Abiotic (Non-living) Components:

      • Inorganic substances like carbon dioxide, oxygen, nitrogen, water, and minerals.
      • Organic compounds (proteins, carbohydrates, fats) connect abiotic and biotic components.
      • Climatic factors classified into atmospheric (temperature, light, humidity, wind, rainfall) and edaphic (soil-related) factors.

    • Biotic (Living) Components:

      • Comprised of diverse living organisms organized into interdependent populations.
      • Removal of a single species can disrupt ecological balance.

    Modes of Nutrition in Biotic Components

    • Autotrophs (Producers):

      • Organisms that synthesize their own food through photosynthesis, like green plants.
      • Convert solar energy into chemical energy.

    • Heterotrophs (Consumers):

      • Organisms dependent on others for food, including humans and animals.
      • Classified into:
        • Primary Consumers (Herbivores): Directly consume producers (e.g., cattle, sheep, deer).
        • Secondary Consumers (Carnivores): Feed on primary consumers (e.g., lion, tiger).
        • Tertiary Consumers: Feed on secondary consumers; top carnivores that are not preyed upon (e.g., leopard, tiger).
