How does pollution affect the ecosystem?
For example: pollutants such as sulfur can lead to excess levels of acid in lakes and streams, and damage trees and forest soils; atmospheric nitrogen can reduce the biodiversity of plant communities and harm fish and other aquatic life; ozone damages tree leaves and negatively affects scenic vistas in protected …
How does pollution affect biotic factors indirectly?
Indirect effects comprise shifts in the abundance of the food plant and changes in plant surfaces, as well as variations in the host plant quality. Pollutants can also lead to alterations at higher trophic levels by affecting predators, parasitoids and pathogens (Riemer and Whittaker, 1989).
Is pollution a biotic or abiotic?
Air pollution itself is an abiotic factor for a given ecosystem, but air pollution doesn’t have abiotic/biotic factors attached to it. Abiotic and biotic factors are terms which refer to ecosystems.
How does air pollution affect abiotic factors?
Deposition of pollutants can impact ecosystems directly or through soil acidification and eutrophication. Ground-level ozone (O3), the most important air pollutant affecting forests worldwide, is known to reduce photosynthesis, growth, and other plant functions.
Is pollution from an oil refinery abiotic or biotic?
Crude oil contamination, an abiotic stress factor and a common environmental contaminant, at toxic levels has negative impacts on plants.
What are the effects of abiotic and biotic interactions?
The abiotic factors will define which organisms are able or not to live in a specified place. The living organisms will constitute the biotic factors, which define if and how can an organism live in a specified environment. So, the abiotic factors are controling the biotic factors of an environment.
What are the 7 abiotic factors?
In biology, abiotic factors can include water, light, radiation, temperature, humidity, atmosphere, acidity, and soil.
What are examples of abiotic factors?
An abiotic factor is a non-living part of an ecosystem that shapes its environment. In a terrestrial ecosystem, examples might include temperature, light, and water. In a marine ecosystem, abiotic factors would include salinity and ocean currents.
How does climate change affect abiotic factors?
The individual climate change inducing stressors are abiotic in nature , and they impose stress on different plant species: these abiotic plant stressors include drought, elevated CO2, temperature (low and high) , waterlogging, rainfall and sunshine intensity, chemical factors (heavy metals and pH).
