Part A

1.0 Abiotic Factors

Abiotic (Non-Living) factors are physical and chemical factors within an ecosystem such as light, temperature, water, atmospheric gases, wind, soil, and oxygen. Part A of the report will explore the abiotic factors present within the Mangrove communities at Myora Springs and the factors present in the Sea-grass community at One mile. The report will compare and contrast these abiotic factors then illustrate how the organisms present within these habitats have adapted.
