Advanced Topics

In a nutshell: Ecosystems depend on complex interactions between organisms and their environment.

## The Web of Life Ecosystems are communities of living things interacting with each other and their environment. These interactions shape the flow of energy and cycling of nutrients. ### Types of Interactions - **Predation**: One organism eats another. - **Symbiosis**: Close relationships, like mutualism (both benefit), commensalism, and parasitism. - **Competition**: Organisms vie for the same resources. ### Ecosystem Dynamics Energy flows from the sun to producers (plants) to consumers (animals) and decomposers (fungi, bacteria). Disruptions to these interactions can impact biodiversity and ecosystem health. ### Impact on Us Ecology helps us understand environmental issues like climate change, habitat loss, and resource management.

Examples

  • Bees pollinate flowers, supporting food crops and wild plants.
  • Invasive species can outcompete natives, disrupting ecosystem balance.
