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.

- 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.
