Ecology: living beings, environment and their relations
What studies ecology
Ecology is a science focused on the study of the multiple relationships that exist between living beings, besides those that exist between them and the environments of planet Earth.
With the significant increase in population in the last two centuries, as well as the advent of industrialization and intensification of urbanization, this science is of fundamental importance to understand the impacts caused by man on the environment. This understanding serves to enable us to take steps (practical actions) so that development can be carried out in a sustainable manner. Ecological knowledge, therefore, is of fundamental importance for the preservation of ecosystems.
Main topics studied by Ecology:
- Ecosystem Components
- Food web
- Food chain
- Ecological niche and habitat
- Trophic levels
- Matter cycle and energy flow
- Relations between living beings (harmonic and inharmonious)
- Ecological Successions
- Population ecology
- Ecological Pyramids
- Biogeochemical cycles (carbon, nitrogen, oxygen and water)
- Terrestrial and aquatic biomes (biodiversity)
- Environmental imbalances caused by human action
- Environmental pollution and its consequences on human life and ecosystems.
- Ecology of metapopulations
- Ecology and evolution
