________ is defined as the total planetary inheritance and the totality of all resources
All living elements—the birds, animals and plants, forests, fisheries etc.—are
While all living elements —the birds, animals and plants, forests, fisheries etc.—are biotic elements, abiotic elements include air, water, land
etc. Rocks and sunlight are all examples of abiotic elements of the environment. A study of the environment then calls for a study of the interrelationship between these biotic and abiotic components of the environment.
Following are abiotic elements except
______ resources are those which can be used without the possibility of the resource becoming depleted or exhausted
________ resources are those which get exhausted with extraction
This implies that the resource extraction is not above the rate of regeneration of the resource and the wastes generated are within the assimilating capacity of the environment
Carrying capacity is the maximum number of individuals of a given species that an area's resources can sustain indefinitely without significantly depleting or degrading those resources.
Absorptive capacity means
The maximum amount of waste material that can be naturally absorbed by the environment on a sustainable basis, without causing environmental damage. Absorptive capacity means the ability of the environment to absorb degradation.
Gases that trap heat in the atmosphere are called greenhouse gases. Carbon Dioxide (CO2); Methane (CH4); Nitrous Oxide (N2O); Fluorinated Gases are the main greenhouse gases.
The atmospheric concentrations of carbon dioxide and CH4 have increased by ____ per cent and ____ per cent respectively above pre-industrial levels since 1750
The correct option is Option D.
Since 1750, the concentration of carbon dioxide in the atmosphere has risen 46 percent.
Since 1750, WMO says, atmospheric concentrations of CO2 have risen 39 percent, those of nitrous oxide have gone up 20 percent and concentrations of methane jumped 158 percent.
