Habitat
Habitat
The natural environment or place where an organism, population, or species lives. It's like the organism's home address.
Population
Population
A group of individuals of the same species living in a specific geographical area. It's the smallest unit of ecology.
Community
Community
A community of populations living together in the same area, including abiotic factors. They are self-sufficient.

Study Notes
Ecosystem Concepts
- Ecosystem: A community of organisms interacting with their abiotic environment.
- Environment: The surroundings where an organism lives, comprising both abiotic (non-living) and biotic (living) factors.
- Organismal Ecology: Studies the interaction of an individual organism with its environment.
- Population Ecology: Focuses on groups of the same species in a specific area.
- Population: A group of the same species in the same area; the smallest ecological unit, dependent on other populations for survival.
- Community: A collection of interacting populations inhabiting the same area, including abiotic factors; a self-sufficient unit.
- Biosphere: The total area where life exists, spanning from the ocean floor to high altitudes.
- Habitat: The specific environment where a species, population, or organism lives; a concise description of the organism's location.
- Biome: The geographical area representing an environment suitable for a particular organism.
- Biomass: The dry weight of organic matter in a group of organisms.
- Flora: Plant populations in a specific area.
- Fauna: Animal populations in a specific area.
Biotic Components
- Herbivores (Primary Consumers): Organisms that eat plants directly (e.g., sheep).
- Carnivores (Secondary Consumers): Organisms that eat other animals (e.g., lions).
- Omnivores: Organisms that eat both plants and animals (e.g., humans).
- Decomposers: Organisms that break down dead organic matter (detritus) into inorganic materials, crucial for recycling nutrients.
Abiotic Components
- Minerals: Solids in the soil, containing essential elements and compounds for life.
- Water: A vital component of ecosystems, serving as a habitat, solvent, and source of minerals.
- Gases: Atmospheric gases (like nitrogen, oxygen, carbon dioxide, and water vapor) essential for life processes.
- Solar Energy: The sun's energy, influencing the density of organisms and seasonal variations in ecosystems.
