Lesson #2: Lesson #2: Habitats Provide Basic Needs for Organisms Pages 15-19

 2 Areas of Focus  A) Survival Needs  B) Limiting Factors of the environment

A) Survival Needs 1.Survival Needs for plants and animals include:  ____________  Food  Air  ___________ 2. a) Habitat: is the ____________ space where a species lives. b) The Habitat must meet the ________________ needs of the species b) The Habitat must meet the ________________ needs of the species

c) Since animals have different needs, animals can only live in certain places in the world (biomes). Example: A polar bear can’t live in a desert

B) Limiting Factors  Any part of the ________________ environment that determines whether or not an organism will be able to survive in an area is called a limiting factor.  5 Non-Living limiting factors:  _________________ ___________________ (rocks, mountains)  Sunlight  Water  _________________

i) Physical Barriers: Includes anything that ___________ an animal’s way from getting to a certain ecosystem. This includes rivers, ocean, mountains B) Limiting Factors

ii)Sunlight Animals need a certain amount of sunlight in order to survive. Depending on how their ______________ is made up (ex. Fur) determines how much sun they need. B) Limiting Factors

iii) Water: all organisms need water however some need __________ water while others needs _____________ water. iv) Temperature: Living things can only live in places if the temperature___________ _______________. They won’t survive if it is too hot or cold. B) Limiting Factors

v) Soil: In nature, soil gets its _________________ from decomposers breaking down waste. ****Soil that has a lot of nutrients can ____ ______________________, making it a better place for animals to live. B) Limiting Factors

TO SUMMARIZE…  Plants and animals SURVIVAL NEEDS are:  LIMITING FACTORS of the non-living environment are:
