This species dietary nutritional intake can vary depending on both abiotic and biotic factors. Wallace believed species were dynamic by responding to biotic and abiotic factors. Nutrient cycling is the movement of nutrients through an ecosystem by biotic and abiotic processes. These disasters could be biotic or abiotic. Phytosensors are genetically modified plants that can report the presence of biotic or abiotic contaminants. Competition is one of many interacting biotic and abiotic factors that affect community structure. Plants are continuously exposed to a range of biotic and abiotic stresses. Competition is only one of many interacting biotic and abiotic factors that affect community structure. BRs have been reported to counteract both abiotic and biotic stress in plants. Thus, adhesion to abiotic and biotic surfaces is often a precursor to infection. Diapause in the tropics is often initiated in response to biotic rather than abiotic components. From one year to another, ecosystems experience variation in their biotic and abiotic environments. As mentioned above, the cuticle contains wax for protection against biotic and abiotic factors. Whittaker classified biomes using two abiotic factors&colon; precipitation and temperature. The wild species possess many diverse traits including disease resistances and abiotic stress tolerances.
