Chapter 5: Ecology and Welfare
Ecology is a critical branch of biology that examines the interactions between organisms and their environment, covering concepts like ecosystems, energy flow, and nutrient cycling. Human activities contribute to ecological issues such as pollution, habitat destruction, and climate change, highlighting the need for sustainable practices to ensure environmental welfare. Emphasizing sustainable development, conservation, and community engagement is essential for preserving biodiversity and natural resources.

Key Concepts
- -- Levels of Organization in Ecology
- Different hierarchical levels including individual, population, community, ecosystem, biome, and biosphere.
- -- Energy Flow
- The transfer of energy from producers to consumers to decomposers, typically stated through the 10% Energy Rule.
- -- Biogeochemical Cycles
- The cycling of essential elements such as water, carbon, nitrogen, and phosphorus through ecosystems.
- -- Sustainable Development
- Meeting present needs without compromising future generations' ability to meet theirs, focusing on economic, social, and environmental balance.
