Ecosystem Biotic Factors Abiotic Factors includes all abiotic and biotic factors in one particular environment Biotic Factors Abiotic Factors the living parts of an ecosystem the nonliving parts of an ecosystem

Examples of Ecosystems Coral Reef in Belize Mountains in Colorado Arizona Desert

Ecosystems Biotic Abiotic do not necessarily have clear boundaries due to biotic and abiotic changes can change daily as things move from one ecosystem to another Biotic Abiotic migration, seed dispersal flood, erosion, drought

include plants, animals, fungi, microorganisms Bio Biotic Factors include plants, animals, fungi, microorganisms Bio = life biotechnology biomechanics biosphere biofeedback biostatistics biography biotic biology

Examples of Biotic Factors

Biotic Factors interact with each other in complex ways parasitism mutualism competition such as also interact with abiotic factors in the ecosystem dependent upon water, minerals, temperature, light **Abiotic factors DETERMINE Biotic factors**

Biotic Factors Competition Predators Microbes Living organisms are affected by the living components of its environment. Competition Predators Food Shelter Mates Light Microbes Dinosaur example

Abiotic Factors A include air, water, soil, temperature, wind, source of energy (usually sun) a, an = not, without abiotic amusia amoral atoxic

Examples of Abiotic Factors

More Examples of Abiotic Factors Abiotic factors include: Sand Elements like: Nitrogen Calcium Special events such as: Fires Hurricanes Floods Volcanic eruptions Tsunamis
