ECOLOGY is the branch of biology that studies relationships between living organisms and the non-living components of the environment in which they live.
Organism’s interactions may be competitive or beneficial. Organisms may interact with one another in several ways. Some of these relationships include producer/consumer, predator/prey, or parasite/host relationships.
Why do we study Ecology?
Curiosity – How does the world around us work? How are we shaped by our surroundings?
Responsibility – How do our actions change our environment? How do we minimize the detrimental effects of our actions? Overfishing, habitat destruction, loss of biodiversity, climate change.
Sustainability – a property of human society in which ecosystems (including humans) are managed such that the conditions supporting present day life on earth can continue.
Ecology helps us understand complex problems in the nature.
