Study Notes
Ecosystem Overview
- An ecosystem is a community of living organisms interacting with their physical environment.
- Components of an ecosystem include both biotic (living) and abiotic (non-living) elements.
Biotic and Abiotic Components
- Biotic components consist of all living organisms such as plants, animals, fungi, and microorganisms.
- Abiotic components include non-living factors like water, soil, sunlight, and climate.
Interactions Among Organisms
- Living organisms interact in various ways, including competition, predation, symbiosis, and mutualism.
- These interactions help maintain the balance and health of the ecosystem.
Definition of Environment
- The term 'environment' encompasses all external factors affecting organisms, including social, economic, and physical conditions.
- The environment refers to the surroundings that provide essential resources for survival.
Importance of Global Summits
- Global summits are held regularly to address environmental issues, climate change, and sustainable development strategies.
- They aim to facilitate cooperation between developed and developing nations for better resource management.
Producers, Consumers, and Decomposers
- Producers are organisms, like plants, that convert inorganic compounds into organic materials using sunlight (photosynthesis).
- Consumers rely on producers for energy; they can be classified into herbivores (plant eaters), carnivores (animal eaters), and omnivores (both).
- Decomposers play a critical role by breaking down dead organic matter and recycling nutrients back into the ecosystem.
Types of Organisms
- Primary producers create energy-rich organic compounds from inorganic substances.
- Herbivores consume only plants, while omnivores consume both plants and animals.
- Parasites live off hosts, deriving benefits while harming the host organism.
Examples of Components
- An example of a producer is grass.
- An example of a decomposer is fungi or certain bacteria.
- Herbivores, such as rabbits, are primary consumers, while omnivores, like bears, consume a mixture of plants and animals.
