Question

List the various abiotic environmental factors.

Answer 1

"The different abiotic environment factors are -

1) Sunlight and Temperature- Sunlight is essential for life to flourish. It provides energy to primary producers such as plants and thus is the central abiotic component.

2) Water- All organisms require a water intake. For instance, Our bodies are made up of 70% water.

Marine animals need a lot of water while desert animals need little but all animals need it.

3) Atmosphere- Without the atmosphere, animals would not get oxygen for respiration and plants would not get carbon dioxide for photosynthesis and life would not be possible.

4) Chemical Elements- All living organisms, especially plants require these. Some plants thrive in acidic soils which some need alkaline.

5) Wind- This is the final abiotic factor, several plants disperse their pollen and even seeds using wind.

Answer 2

Answer:

Abiotic environmental factors are formed by all the non-living components of an ecosystem which includes the following:

Temperature –

It is one of the most significant factors which varies seasonally on land, progressively decreases from the equator towards the poles, from plains to the mountain tops.

Water –

Life cannot sustain without water. For marine entities, pH, water temperature, chemical composition etc is significant. It is also affected by water salinity that is less than 5 parts per thousand in inland water, 30-35 parts per thousand in sea etc

Euryhaline are entities which can bear a wide salinity range whereas stenohaline are entities that can tolerate a narrow range of salinity. Most of the fresh water animals cannot sustain in sea water for long due to osmotic issues that arise due to high salinity and vice-versa

Soil –

Properties and nature of soil varies from place to place, depending on the following factors

-climate

-soil development process

-Weathering process

Characteristics such as grain size, aggregation, soil composition determine the water holding capacity and percolation of soil. Along with these, some other features such as pH, topography, mineral composition etc determine the type of type of plant that can grow in a specific habitat.

Light –

All autotrophs depend on light to carry out photosynthesis, releasing oxygen during the process. In forests, small herbs and shrubs are adapted to photosynthesis under very low light intensities as they are overshadowed by tall trees.
