Envi & Eco Concepts

A study of interrelationship of different organisms with each other and with their environment. Ecology
a) A Greek word meaning habitat or place of living. b) A Greek word meaning to study. a) Oikos b) Logos
A German biologist, naturalist, philosopher, physician, professor, marine biologist, and artist, who defined ecology as the study of the relationship of organisms with their environment. Ernst Heinrich Philip August Haeckel (1869)
Two people who stated that ecology is the study of the ditribution and abundance of organisms. Andrewartha and Birch (1954)
The person who stated that ecology is the study of ecosystems. Eugene Odum (1971)
A factor of ecology that includes ambient temperature, amount of sunlight, and pH of the water in which an organism lives. Abiotic factors
A factor of ecology that includes the availability of food organisms, and the presence of conspecifics, competitors, predators, and parasites. Biotic factors
A classification of ecology that deals with the study of individual species, organisms, and its population. Autecology
A classification of ecology that deals with the study of communities, their composition, their behavior, and relation with the environment; aka Ecology of Communities. Synecology
