2. INTRODUCTION: A  habitat  is an ecological or environmental area that is inhabited by a particular species of animal, plant or other type of organism. The term typically refers to the zone in where the organism lives and find food, shelter, protection and mates for reproduction. It is the natural environment in which an organism lives, or the physical environment that surrounds by a species population.

3. DEFINITION OF HABITAT: The word "habitat" has been used since about 1755 and derives from the Latin word. It means to have or to hold. Habitat can be defined as the natural environment of an organism in where it live and grow. It is similar in meaning to a biotope, an area of uniform environmental conditions associated with a particular species of plants and animals .

4. TYPES OF HABITATS : There are so many type of habitat in the world. Terrestrial habitat include Forests, Grasslands, Wetlands Deserts etc. Many of these habitats grade into each other and each one has its own typical communities of plants and animals. A habitat may suitable for a particular species well.

5. FRESH WATER HABITAT: Freshwater habitats include rivers, streams, lakes, ponds etc .Although some organisms are found across most of these habitats, and the majority have more specific requirements.

6. MARINE WATER HABITAT : Marine habitats include brackish water estuaries, bays, open sea, sea bed, reefs and deep water zones. Further variations include rock pools, mudflats, brackish lagoons, sandy beaches, and sea grass beds. all of these supporting their own flora and fauna

7. DESERT HABITAT : A desert is the kind of habitat that favors the presence of amphibians, with their requirement for water to keep their skins moist and for the development of their young. Some frogs live in deserts, creating moist habitats in hibernating condition and underground while conditions are adverse.

8. MICROHABITATS: A microhabitat is the small-scale physical requirements of a particular organism or population. Every habitat includes large numbers of microhabitats with subtly different exposure to light, humidity, temperature, air movement, and other factors.

9. EXTREME HABITATS : Although the vast majority of life on Earth lives in mesophyllic environments, but few organisms, most of them are microbes are managed their colonies in extreme environments that unsuitable for higher life forms. for example, living in Lake  . MONOTYPIC HABITAT : A monotypic habitat is a single species of animal or plant is so dominant to other species. Ex-The monotypic habitat occurs in botanical and zoological contexts

10. HABITAT CHANGE: Whatever from natural processes or the activities of man habitats change over time. The main reason is Earthquakes, Storms, Flooding, Wildfires, Coastal erosion, Deforestation, Change in land use. ENVIRONMENTAL FACTORS : The chief environmental factors affecting the distribution of living organisms are temperature, humidity, climate, soil type and light intensity. These also help to change the habitat.

11. Habitat destruction : In the simplest term, when a  habitat  is  destroyed , the plants, animals, and other organisms that occupied in habitat  have reduced carrying capacity so that populations become decline and extinct. Perhaps the greatest threat to organisms and biodiversity is the process of  habitat loss. Cause of habitat destruction ? There are so many reason for habitat destruction these are- Increasing food production. Mining. Forest fire. Overgrazing. Building roads and cities.

12. Marine habitat and destruction . Marine  life depends in the saltwater that is in the sea. Marine habitat destruction include Pollution. Logging. Draining of wetlands . Coastal development. All factors that lead to  marine habitat destruction . .

13. Effects of habitat destruction . There are many  effects of habitat destruction these are basically Animal extinction. Effect of food chain. Loss of resources. Climate change. Effect of land. Global warming. Pollution increases. Invite disasters.

14. HABITAT CONSERVATION : Habitat conservation is a management practice that conserve, protect and restore habitat areas for wild plants and animals, especially conservation reliant species.  Marine sites that prohibiting the fishing, mineral extraction, and other habitat-altering activities. Land use based on scientific way and needed to protect the coastal areas. Some conservation efforts are empowering for monitoring water quality.

15. CONCLUSION: However, since the environment (habitat) is a complex, variable and extensive system, protecting the environment is a hard task. It is impossible that all the existing pollution problems in the environmental can completely be solve in the next decade. It is the responsibility for everyone to protect our environment. Let us fulfill our responsibilities in environmental protection , creating a quality ecological environment and sharing wonderful green living earth.
