3. What are the levels to the ecological hierarchy ?

4. ORGANISM :- Study of individual organism in its environment. FOCUSED ON: Physiology Behaviour Survival strategies Adaptations

5. POPULATION :- Group of individuals of the same species living in a specific area. FOCUSED ON: Poplution size, Birth rate, Death rate poplution density Age pyramid, poplution abundance poplution dispersion pattern

6. COMMUNITY :- Different poplution of organisms living together in a particular area and interacting with each other. FOCUSED ON: Species diversity community structure Species interaction

7. ECOSYSTEM :- An ecosystem includes the community of living organisms along with the physical environment in a particular area. FOCUSED ON: Energy flow Nutrient cycling

8. LANDSCAPE :- This group considers clusters of interacting ecosystems. FOCUSED ON: Ecosystem interaction Beta diversity Gamma diversity

9. BIOME :- Biomes are large ecological areas on the Earth’s surface, with flora and fauna adapting to their environment.

10. BIOSPHERE :- The biosphere is the global ecological system ineracting with all living beings and their relationships with the lithosphere(land), hydrosphere (water) and atmosphere(air).
