This document discusses natural resources and their importance in science. It defines natural resources as materials that exist naturally within the environment without human disturbance. Some key natural resources mentioned include forests, ponds, rivers, wetlands, and marine environments. Forests regulate climate, store carbon, and contain high biodiversity. Aquatic ecosystems like ponds and rivers provide habitat for many organisms. Wetlands are highly productive. Oceans contain living resources like algae and animals, as well as non-living resources like minerals. Natural resources are important in science for studying organisms, ecosystems, nutrient cycles, and conducting research. They are the source of many raw materials and specimens used across various scientific fields.

2. NATURAL RESOURCES
IN SCIENCE

3. INTRODUCTION
Natural resources are the resources
occur naturally within the environment, The occur relatively un
disturbed by humanity, in a natural form. Any thing people can
use which come from nature is called natural resources Forest,
pond, lake,sea are examples of natural resources. every
manmade product is composed of natural resources. Natural
resources contain biotic and biotic facors.Natual resources play
very important role in science and researches.Natural resources
ply very important role in maintaining climate. People do not
make natural resources but gather them from the earth .The
natural resources are exploited by man for economic gain the
progress of mankind depends upon the exploitation of different
natural resource Some natural resources such as sunlight and air
can be found everywhere, and are known as ubiquitous
resources. However, most resources only occur in small
sporadic areas, and are referred to as localized resources. There
are very few resources that are considered inexhaustible (will
not run out in foreseeable future) – these are solar radiation,
geothermal energy, and air (though access to clean air may not
be). The vast majority of resources are exhaustible, which
means they have a finite quantity, and can be depleted if
managed improperly.

4. The important natural resources in science are ,
Forest
Forest is a natural ecosystem. Forest consist of
both biotic and a biotic factors. Soil moisture, air, sun light are
biotic factors in the forest. Green plants are the producers in
forest ecosystem. Animals ,birds and other living organisms are
consumers in forest. Forest is a resource of large number of trees
and animals. It is the area containing very rich biodiversity.
Usually forest is an area with high density of trees.
Forest act as a habitat for organisms and soil
conservers. A typical tree forest is composed of the canopy
(upper tree layer) and under story. Under story is further divided
in to shrub layer and herb layer. Forest are central to all human
life because they provide a diverse range of resources, the store
carbon, aid in regulating planetary climate and purify water.
Forest also contain roughly 90 percentage of the world
terrestrial biodiversity. Forest play very important role in
maintaining climate and reduce high temperature of atmosphere.
Forest give wood fruits essential oils latex, resins etc.. The
regulative function of carbon dioxide and oxygen. Forest
regulate climate floods and drought and the global biochemical
cycle

5. POND
Pond is a aquatic natural recourse. It is source of both
biotic and a biotic resources. Forest is habitat for many small
organisms and fishes. Pond is surrounded by trees,shrubs and
herbs. The abiotic components in pond ecosystem are water,
Dissolveed minerals oxygen and carbon dioxide. The biotic
components are small fishes,frog earthworm,watersnakes,
phytoplanktons algae water plants etc
RIVERS
Rivers are the shallow whater.the velocity of water the
shallow water keep the bottom clear in river.Filamentous algae
and fishes are common in river.River is anatural water course
usually fresh water.River is asource of different type of aquatic
organisms.River usually flowing towards an ocean,lake or sea or
another river.Rivers have been used as a source of
water,food,for transport and rivers are related to man’s cultural
development
WET LANDS
Wet lands are low-lying areas,usually covered by
shallow water and have characteristic soils and water tolerant
vegetation. wet lands may be either fresh water or salt water.
Fresh water wet lands include marshes and swamps wet lands
are highly productive and provide food and provide food and
habitat to support wide variety of organisms fresh water

6. wetlands also provide important commercial products including
wild rice and various berries.In addition wet lands provide sites
for fishing,boating nature study etc
MARINE RESOURCES
About three fourth of earth’s surface is occupied
by oceans. Marine resources can be broadly divided in to two
major categories such as living resources and non living
resources, living resources include the algae and the animals of
the sea non living resources include various kinds of minerals.
Marine algae are use for commercially important products.
Animal resources like fishes are used for manufacture of many
edible products like food, fish oil, fish proteins and vitamins
different type of molluscs, crustaceans and mammals are also
present in sea
The sea is store house of many viable
minerals most abundant elements in he sea are sodium chloride,
magnesium and bromine that are commercially extracted from
sea water.

7. IMPORTANCE OF NATURAL RESOUCES IN SCIENCE
Natural resources help know about organisms and their
natural habitat. Natural resources are the source of different type
of specimens in biology. It also help to rise pupils curiosity.
Taxonomy and morphology of different type of organisms are
studied on the specimens collected from nature.Natural
resources help to know about general characteristic and life
history of forest trees and crop with particular reference
environmental factors as the basis of different studies. Natural
resources help to know about energy transfer, nutrient cycle and
different type of relation ship between organisms.It help to
study about Ecosystem,food chain and food web and economic
importance of natural resources
CONCLUTION
Natural resources occur naturally within environments that
exist relatively undisturbed by humanity, in a natural form.
Natural resources include total natural environment,that is the
entair surface layer of earth so the natural resources are the
components of atmosphere,hydrosphere and lithosphere.A
natural resource is often characterized by amounts of
biodiversity and geodiversity existent in various ecosystems.
Natural resources are widely used in different type of studies in
science of many raw materials forest,sea,lakes, pond etc are
some natural resources used in science.They are the source of

8. food and many usefulmaterials.they are also used in different
type of ecological studies and reserches.
