It encompasses several fundamental concepts:

1. Ecosystem: A community of living organisms interacting with each other and their physical environment.
2. Abiotic & Biotic Factors: Abiotic factors are non-living components (like temperature, water, sunlight), while biotic factors are living components (organisms, plants, animals).
3. Population: A group of individuals of the same species living in a particular area.
4. Community: Different populations of species living and interacting within a specific area.
5. Habitat: The specific environment where an organism lives and thrives.
6. Niche: The role an organism plays within its ecosystem, including its interactions with other species and its environment.
7. Food Chains & Food Webs: Represent the flow of energy and nutrients through an ecosystem, showing who eats whom.
8. Energy Flow: The transfer of energy through different trophic levels in an ecosystem, from producers (plants) to consumers (herbivores, carnivores), and decomposers.

Understanding these concepts helps in appreciating the complexity of interactions within ecosystems and how they influence the distribution and abundance of life forms on Earth.
