1. Abiotic factors All of the Non living parts of an environment the affect the ecosystem

2. Abiotic factors Non-living parts of an environment Air Water Soil Sunlight Temperature Climate

3. Abiotic factors Air Atmosphere surrounds Earth CO 2 = carbon Dioxide N = Nitrogen O = Oxygen Other trace gases Photosynthesis H 2 O + sunlight + CO 2 = sugar for use of living things to” 1. get and use energy. 2. grow and develop. 3. to reproduce. 4. to respond to their environment. Respiration uses oxygen to burn sugar and produces O 2

5. Abiotic factors Water necessary for life Photosynthesis Respiration digestion

6. Abiotic factors Soil Dirt is the basic mineral component of soil. Sand– largest component, 10 times larger that silt Silt– medium-sized component, 10 times larger than clay Clay– smallest component measuring 1 micrometer in length and width, the same size as bacteria Soil is composed of the basic mineral content of dirt but includes organic matter and microorganisms. Sand Silt Clay Organic Matter (dead decaying material) Microorganisms of all kinds

7. Dirt Soil

8. Abiotic Factors Sunlight Energy source for most all life on earth Producer = performs photosynthesis (plant) makes its own energy (food) Consumer = gets energy from either a producer or another consumer (cannot make its own food) Temperature Body temperatures = 0 C / 32 F to 50C/122F Location amount of sunlight it gets Latitude = how far North or South of the Equator Angle of Sunlight Tilt of earth on its axis's

11. Sunlight Time of year = length of daylight hours at a location = Winter path = spring/fall = Summer

12. Abiotic factors Climate vs Weather Weather = is the day-to-day state of the atmosphere in a region and its short-term Weather = the combination of temperature, humidity, precipitation, cloudiness, visibility, and wind Measured over a short period of time

13. Abiotic factors Climate vs weather Climate = the average conditions expected at a specific place at a given time Climate = may include precipitation, temperature, humidity, sunshine, wind velocity, phenomena such as fog, frost, and hail storms over a long period of time Climate = weather statistics over long period of at least 30 years ("climate normals").
