Understanding Ecology: Biotic and Abiotic Factors in Ecosystems

This section explores the fundamental concepts of ecology, highlighting the interactions between living organisms (biotic factors) and their non-living environments (abiotic factors). It defines key terms such as organism, population, community, ecosystem, and biosphere, illustrating how these components are interconnected. Examples include various organisms like trees and fish, as well as abiotic elements like air and soil. Understanding these relationships is crucial for comprehending the dynamics of ecosystems and the overall health of our planet.

  3. Can you identify the biotic & the abiotic factors in this scene?

  4. Organization in the Environment • Organism- An individual living thing. • Population-A group of organisms of the same species that live in a specific area. • Community-All the populations of species that live in the same habitat and interact with each other. • Ecosystem- A community of organisms and their aboitic environment. • Biosphere- The part of the Earth where life exists.
