Both biotic and abiotic factors contribute to making up an ecosystem. The living parts form the biotic components while the non-living parts form the abiotic components. They play a significant role in shaping up an ecosystem and are inter-dependent on each other, hence a change or removal of any one component also affects the whole ecosystem. A few examples of both these factors are:
- Biotic – Animals, plants, Humans, Microorganisms
- Abiotic – Water, wind, soil, temperature, pressure, humidity
The range of biotic and abiotic factors spreads across the whole biosphere or the entire ecosystems. These factors can have pertinence for an individual in a species, its community or a whole population. For example, a disease is a biotic component that affects the survival rate of individuals in its community, another instance is temperature with the same relevance.
Biotic factors often tend to change the geography and geology of an area. Entities, geographically create topsoil by disintegrating the layers of rock and dying that provides detritus to form new soil and replenish the ground with nutrients.
Biotic And Abiotic Factors
Here is a list of four interactions between biotic and abiotic factors in nature:
- The formation of the Grand Canyon
It is a gigantic gorge which stretches over 200 miles long of the Colorado River that is situated in Arizona. It was sculpted for over millions of years by erosion from the river and its tributaries. It has a history of approximately 2 billion years of the geological history of the Earth and flashes several layers of rock. It is a naturally produced gorge through the interaction between abiotic factors.
- The melting of ice sculpture into a puddle
It is contributed by the abiotic components such as the ambient temperature which causes the melting of the ice.
- Acid Rain
It is caused due to various biotic factors such as human activities causing pollution thereby contributing to the acidic nature of the precipitate. The acidic nature is due to the excessive amounts of nitrogen and sulphur released by transport vehicles.
- Global warming
Entrapment of greenhouse gases such as methane, carbon dioxide etc causes global warming. These gases prevent the outflow of infrared radiations thus causing the warm temperature of the Earth. Increase in the levels of these gases can be contributed to the excessive release of gases from industries and burying of fossil fuels which are causing the rise in global temperatures.
To understand the biotic and abiotic components in depth, comprehension of the configuration of these biotic components is essential. All living entities at the crux of it are originated from cells. Cells are the structural and functional units of living entities. Living entities are grouped into unicellular and multicellular entities, depending upon the cellular constitution, distribution of cells, number of cells. Most familiar plants are multicellular eukaryotic entities. The ultrastructure of the plant cell diagram needs to be studied in order for us to analyze each component of the cell and their functionalities.
