9/6/16 Notes Environmental Bio Ecology Ecology the scientific study of interactions amongst living things and or organisms that help each other out within their environment. ~Ecology goes beyond study of biology since chemistry can be involved Ecosystems characteristics ~Dynamic ~Leaky ~Unclear boundaries ~Can be big or very small area wise Abiotic/Biotic Main factors are of ecology are abiotic and biotic Biotic factors are all the living things and or living organisms. Biotic factors are physical. Abiotic factors are all nonliving and these factors are not physical. EX’s: temperature, sunlight. Interactions with abiotic/biotic AbioticBiotic AbioticBioticBiotic (very common) BioticAbioticBiotic ~Biotic factors can help abiotic factor Abiotic Components of Ecosystems Sunlight Wind Temperature Precipitation(rain) Nutrients (Calcium, phosphorus, nitrogen, etc) Sunlight varies due to… Latitude: the angular distance of north or south towards the earth’s equator. Expressed in degrees and minutes Seasons Covering clouds Vegetation: Plants that are found in a particular area Temperature varies on earth due to… Latitude due to sunlight Biomes on earth Polar IceTundraConiferous ForestNorthern deciduous ForestTropical rainforest ~Altitude goes up with biomes Altitude the height of a point in relation to its ground or sea level ~Temperature effects the water availability in a biome Biome A natural occurring area of flora and fauna that occupies a habitat. Winds High to low pressure Circulates the Earth Precipitation (rain) Regimes(govt.) Much more dryness on the west coast so more deserts Much more wetness on the east coast so more wetlands Water availability have a big impact on nutrient availability since you need nutrients in order to help with productivity since plants rely on nutrients in order to grow. Circulation and Geomorphology Moist air mass ascends ridge(windward) heavy precipitationDrier Air and descends windsRain shadow region(leeward) Windward is towards the wind and leeward is away from the wind. Geomorphology the study of physical features on the surface of the Earth in relation to their geological structures Microclimates The climate of a restricting and or very small area, especially when we see a differ in climate within the surrounding area Bog A type of wetland that’s wet and very muddy with ground too soft.
