Many subcategories… Which one are you interested in? › Animals, plants, insects › Biomes (formations that exist over regions.. The Arctic, the tropics, the desert) Ways to study ecology: › Field studies - very common › Laboratory studies › Computer Simulations What possible environmental change in the future could be studied?
Organisms environments include two different properties: › Abiotic: physical, non-living properties Sunlight, climate, soil, water, air › Biotic: Biological, living properties Other organisms same or different species in the same habitat
Wide range of levels – from smallest to largest › Individual level › Population › Community › Ecosystem › Biome › Biosphere
Two or more individuals of the same species Occupy the same area Interact with one another
Two or more populations of different species Occupy the same area Interact with one another
Living and non-living (biotic and abiotic) factors in an area interacting with each other
Regions organized by climate (Arctic, Grasslands, Tropic, Desert, etc.)
Terrestrial Tundra – › Located between the ice-cap and timber line of North America, Europe and Asia. Little rain, soil is frost, short plants, very cold Taiga › Subartic coniferous forests, south of the tundra. Temperate › Forests. Moderate rain, fertile soil, 4 seasons. Grasslands › Lands dominated by grasses. Fertile soil. Deserts › Hot, Dry, Poor soil, hot days/cold nights. Tropical Rain Forest › Hot year round, a lot of rain Aquatic Fresh Water › Rivers, lakes, ponds, swamps Salt Water › Ocean, Salt lakes and seas. Largest amount of life.
