HABITAT, ENVIROMENT AND SURVIVAL HABITAT, ENVIROMENT AND SURVIVAL Presentation Transcript

  • HABITAT,ENVIROMENT AND SURVIVAL PRESENTED BY; SURAYYA MUHD LAMIDO 20122555 ECOLOGY
  • Explore the World Around You!
  • COMMUNITY A community is all the living organisms in a habitat. Plant communities that have many layers of vegetation can support more species of birds than a plant community that has a simpler structure.
  • ECOSYSTEM The system formed by a community of living organisms interacting with one another and their physical surroundings is an ecosystem. Community + physical surroundings = ecosystem
  • ENVIROMENT The sum total of all surroundings of a living organism, including natural forces and other living things, which provide conditions for development and growth as well as of danger and damage. Environment is the biotic and abiotic surrounding of an organism or population, and includes particularly the factors that have an influence in their survival, development and evolution.
  • HABITAT A habitat is an ecological or environmental area that is inhabited by a particular species of animal, plant, or other type of organism.It is the natural environment in which an organism lives, or the physical environment that surrounds a species population.
  • CONT… A habitat is made up of physical factors such as soil, moisture, range of temperature, and availability of light as well as biotic factors such as the availability of food and the presence of predators. A habitat is not necessarily a geographic area—for a parasitic organism it is the body of its host or even a cell within the host's body
  • Which habitats do you recognize?  Desert  Grassland  Rain  Forest Forest  Tundra  Prairie  Marine  Zoo
  • Desert Super-dry air  Little rain – less than 10 inches a year  High daytime temperatures  Lots of wind  Typical animals include insects, reptiles, birds, and various mammals 
  • Rain Forest The Rain Forest is made of 3 layers  The first layer is the canopy  The second layer is the understory  The third is the forest floor  The Rain Forest contains about 45% of all animal species 
  • Tundra Extremely short growing seasons (6 to 10 weeks)  Long, cold, dark winters (6 to 10 months)  Low Precipitation  Snow provides insulation  Wildlife includes birds, reindeer, foxes, bears, seals, and walruses 
  • Prairie Temperatures vary summer to winter  Moderate rain fall  Seasonal drought and occasional fires  Typical animal life includes jack rabbits, deer, foxes, coyotes, birds, and many other species 
  • Savannah Warm, hot climates  Major vegetation is grass  Dry and rainy seasons  Seasonal fires help maintain balance  The Savannah is home to various reptiles, rodents, birds, and large mammals such as elephants, and zebras 
  • Forest Covers 1/3 of the Earth’s area  Dominated by trees and woody vegetation  Precipitation is distributed evenly throughout the year  Animal life includes many things such as bears, deer,and rodents 
  • Marine Water covers nearly 75% of the Earth’s surface  There are numerous species of plans and animals who live here.  These range in size from microscopic organisms to the size of a 100 ft whale. 
  • Zoo A place where people keep and display animals  A man made habitat  Zoos are important for 3 major reasons  Recreation and education  Wild life conservation  Scientific studies 
  • NICHE The niche of a species is that part of the environment in which the species survives, reproduces and is likely to persist.
  • Abiotic factors The physical environmental factors that affect the survival of organisms in fresh water include light, temperature, dissolved gases and nutrients.
  • Protect the wonderful world around you!  Remember each habitat is a unique place where plants and animals make their home.  What makes your habitat unique? 
  • THANK YOU….
