1. | All the biological factors in the organism environment |
2. | The physical space where an organism lives |
3. | The range of temperature that the organism needs to live |
4. | The functional role played by the organism where it lives |
The four levels of biological organization to which Ecology is basically concerned are:
1. Macromolecules-tissues-populations-biome
2. Macromolecules-organisms-population-biome
3. Tissues-organs-community-biome
4. Organisms-Populations-Community-Biome
Regional and local variations within each biome lead to the formation of a wide variety of:-
1. Niche
2. Population
3. Microclimate
4. Habitat
