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.
