Sustainable conditions and physical factors of the given region

Sustainable development is a pattern of resource use, with thepurpose of meeting human necessities while conserving the environment so thatthese needs can be met not only in the present but also for generations to come.Increasing population growth rates is a challenge that the future generationsare facing, which results in the rise of need for more resources for energy. Thereforenatural resources should be liberally secured in spite of intense humanactivity.

Sustainable development is influenced by three major factors such asenvironmental, economic and socio-political factors. Therefore these goals mustbe met to achieve sustainable development. For example to guarantee asustainable development there must be a healthy population that is economicallyempowered, with a sensible mind, educated and with preferable values. Such typeof population is as an effect of good governance and proper policies. Some ofthe factors essential for sustainable development comprise of; right managementof natural resources, poverty abolition, proper utilization behaviors that willlead to sustainable production patterns and proper policies in respect of environmentmanagement and investment.  Wasteland Reclamation means re-claiming it or to use it forproductive purpose.

Solar energy provides all the energy for theecosystem.ü Inorganicsubstances: Sulphur, boron, etc.

ü Organiccompound, such as proteins, carbohydrates, lipids etc.ü Climaticconditions and physical factors of the given region 2.BIOTIC COMPONENTS          Thebiotic components of an ecosystem include all the living components.

In thistype of classification, these are: i)Autotrophs (primary producers)a) Phototrophs uses sun’s energy and store it in complexorganic compounds eg: green plants, algae etc.b) Chemoautotrophs produces complex organic compounds byoxidizing reducing inorganic substances.   Eg: bacteria ii)Heterotrophs(consumers)these organisms cannotproduce their own food. a) Macro consumers: Theyfeed on organisms or particulate organic matter.Eg.

Herbivores, carnivores,omnivores.b) Micro consumers or decomposers: They feed on dead anddecaying matter eg: bacteria and fungi        2. Suggest measures for conservation andmanagement of natural resources.

 Ans: Natural resource management denotes tothe management of natural resources such as land, water, earth, plants andanimals, with a specific attention on how management affects the value of lifefor both existing and upcoming generations. Needfor Conservation of Natural Resourcesü topreserve ecological equilibrium for supporting life.ü toreserve different kinds of species (biodiversity).
