Abiotic and Biotic Factors of an Ecosystem

By Bharat Choudhary -
An ecosystem is defined as any community of living and non-living things that work together. Each ecosystem is unique. To understand this, we need to look at the biotic and abiotic factors within them -

Abiotic Factors Vs Biotic Factors
Abiotic and Biotic Factors of an Ecosystem


Both biotic and abiotic factors are related to each other in an ecosystem, and if one factor is changed or removed it can affect the entire ecosystem. Abiotic factors are especially important because they directly affect how organisms survive.




 Abiotic Factors: Abiotic factors are those non-living physical and chemical factors which affect the ability of organisms to survive and reproduce. Abiotic factors vary in the environment and determining the types and numbers of organisms that exist in that environment.   Factors which determine the types and numbers of organisms of a species in an ecosystem are called limiting factors.   Many limiting factors restrict the growth of populations in nature.  An example of this would include low annual average temperature average common to the Arctic restricts the growth of trees, as the subsoil is permanently frozen.

 Biotic Factors: Biotic factors are all the living things or their materials that directly or indirectly affect an organism in its environment.   This would include organisms, their presence, parts, interaction, and wastes.  Factors such as parasitism, disease, and predation (one animal eating another) would also be classified as biotic factors.

ABIOTIC COMPONENTS
BIOTIC COMPONENTS
Sunlight
Primary producers
Temperature
Herbivores
Precipitation
Carnivores
Water or moisture
Omnivores
Soil or water chemistry (e.g., P, NH4+)
Detritivores
These can vary among different ecosystems

Continent Wise Classification and Distribution of Local Winds

By Bharat Choudhary -
Image
Local winds are small scale convective winds of local origin caused by temperature differences. Local terrain has a very strong influence on local winds, and the more varied the terrain, the greater the influence. These occur on a small spatial scale, their horizontal dimensions typically several tens to a few hundreds of kilometers. They also tend to be short-lived lasting typically several hours to a day. There are many such winds around the world. Most common local winds are  sea breezes and land breezes, Anabatic and katabatic winds, and Foehn winds. Land Breezes and Sea Breezes:   As the names suggest, the two breezes occur along coastal areas or areas with adjacent large water bodies. Water and land have different heating abilities. Water takes a bit more time to warm up and is able to retain the heat longer than land does. Now let us see the following Diagram - Land Breeze:  It's  a coastal breeze blowing at night from land to sea, caused by the differe

Is God A Woman?

THE SHAKTI PRINCIPLE Is God A Woman? Shakti literally means power but a different kind of power—the power of beauty, intuition, nurturing, and tenderness. DEEPAK CHOPRA Image Source :   http://www.carolinejariwala.com/ No God is not a woman, but God's feminine face has been ignored for too long. The masculine energies have dominated our culture for centuries and because of that we have become a predatory species. We are the only animal that kills our own kind most frequently in the name of God. The feminine forces of the universe are desperately needed if we have to evolve into our next stage of development.  "The whole universe is a gesture of erotic love and every dancing molecule is moving in longing for an unseen lover." God, being infinite intelligence, cannot be squeezed into the volume of a body or the span of a lifetime. Nor can God be conceived of in human form. Nevertheless, God can be symbolised in masculine and feminine forms. The masculine form needs to be pu

Soil Geography - Zonal, Intrazonal and Azonal Soils (Older System of Classification)

By Bharat Choudhary -
Image
Soil geography deals with the distribution of soils as function of the five recognized soil-forming factors (climate, flora and fauna including Man, relief, parent material, time), either acting singly or in combination. It forms the basis of such concepts as zonality (i.e. the regional distribution of soils in zones), first formulated by Dokuchaev on the basis of climate for European Russia, elaborated upon further by Glinka and Sibirchev, who introduced the zonal, intrazonal and azonal soils approach, taking into account other soil-forming factors than climate. The loose material or the upper layer of the Mantle Rock, t he soil system, is the product of environmental and biological processes in interrelation with climate, vegetation (flora), animals (fauna), underlying rocks, topography and time which affect the biosphere. This is the  Zonal ( Older ) System of Classification .  This system links the distribution of various soil types to the distribution of climate
