CARRYING CAPACITY and ECOLOGICAL BALANCE
INTRODUCTION
The carrying capacity and ecological balance is of vital importance for the stable functioning of an ecosystem
Carrying capacity is defined as the maximum persistently supportable load of a focal population in a bounded
environment
Ecological balance is a term describing how ecosystems are organized in a state of stability where species coexist
with other species and with their environment
By examining carefully the requirements of a given species and the resources available, it might be possible to estimate the carrying capacity of that environment for the species
For humans carrying capacity is much more complicated, while human beings play a key role to maintain ecological balance as they have the highest thinking capacity as compared to other living organisms.
This balance is very important because it ensures survival, existence
and stability of the environment
CARRYING CAPACITY
The carrying capacity of a biological species in an environment is the maximum population size of the species that the environment can sustain indefinitely, given the food, habitat, water and the other necessities available
in the environment
As population density increases, birth rate often increases and death rate typically decreases
The difference between the birth rate and the death rate is the “natural increase”
The carrying capacity is the number of individuals an environment (with all
the limiting factors) can support without significant negative impacts to the given organism and its environment
Sometimes population size decrease above carrying capacity due
to a range of factors depending on the species concerned but there may be insufficient space, food supply or sunlight
The carrying capacity of an environment may vary for different species and may change over time due to a variety of limiting factors including: food availability, water supply, environmental
conditions and living space
The origin of carrying capacity
From the industrial revolution in the latter half of 18th century, the natural civilization of human beings is developed highly in the process of exploiting and making use of natural resources
Along with the achievements brought by the industrial civilization, a series of problems came up
pollution of air and water, soil loss, desertification becoming
larger, climate changing abnormally, biological species decreasing quickly, the shortage or exhaustion of resources, the destruction of ozone layer, population increase etc were the problems
In 1912, the concept came into form
Park and burgers proposed the concept of carrying capacity
They held the opinion that the carrying capacity of population in one region can be determined according to several factors
The evolvement and development of the concept of carrying capacity can be traced differently through the ages
Methods to evaluate ecological carrying capacity
The methods include the natural vegetation NPP method, the balance law of supply and demand, the state space method, the ecological footprint method, comprehensive evaluation methods and so on
The vegetation NPP refers to the amount of organic compounds accumulated by vegetations in one unit of time and area
It reflects the productive capacity of vegetation community in the natural environment
NNP is an important index for evaluating the framework and functional features of ecosystem and the capacity of ecosphere for carrying human beings
It is also an important index for estimating the supporting ability of the earth and evaluating the continuous development of the ecosystem in land
Ecological balance
Ecology is the science of the study of ecosystems
Ecological balance has been defined as a “state of dynamic equilibrium within a community of organisms in which genetic, species and ecosystem diversity remain relatively stable, subject to gradual changes through natural succession”
the most important thing is that the natural balance in an ecosystem is to be maintained
This balance may be disturbed due to :
a)
the introduction of new species
b)
The sudden death of some species
c)
Natural hazards
d)
Man made causes
The harmonious relationship reflect healthy and desirable ecological balance
Survival of all organisms is actualized due to ecological balance
Favourable ecosystem ensures that each organism thrive and multiply as
expected.
Ecological imbalance leads to many problems
There are certain causes that lead to the ecological imbalance and also the ways by which the problems are solved in-order to have a balanced ecology
Causes of ecological imbalance
Introduction of synthetic products
Throwing toxic waste into the bodies of water
Degradation of land and soil
Deforestation
Faulty utilization of water resources
Consequences of ecological imbalance
Pollution
Degradation of natural resources
Soil disintegration
Deforestation
Consumption of natural life
Exhaustion of mineral assets
Ways to control ecological imbalance
Manage natural resources carefully
Control the population
Protect the water
Conclusion
When the carrying capacity of an ecology is crossed, it may lead to the imbalance in ecosystem
The ecological balance brings the existence of the world
The earth gets to produce enough resources for all its species
When the equilibrium is achieved all the organisms are benefited from it and protects all
The destruction of human resources by human beings leads to the ecological imbalance
Each and every organism together contribute to a balanced ecosystem
