Geo2:Chapter 3

-determine where on earth that species may be found, and species with wide ranges of tolerance will be most widely distributed

-refers to the environmental conditions under which a species will prosper

• -change position during the day to increase/decrease exposure to light
• -Ex. Sunflower

-study of seasonal patterns of plant and animal life

relationship between phenology and light

-shed their leaves/needles all at the same time

-replace their leaves/needles gradually 

-large leaves at winter and small leaves at summer 

• -animal whose temperature varies
• Ex. cold-blooded, fish, reptiles

• -animal that maintains stable internal body temperature
• -Ex. warm-blooded mammals

spending winter in a dormant condition 

• spending summer in a dormant condition 
• Ex. Crocodile 

-the body size of the subspecies increases with the decreasing temperature of its habitat 

• -animals that live in cold climate have shorter extremities, such as ears, than related species that live in warm climates
• -Ex. artic fox has tiny ears to conserve body heat in a cold environment
• -Ex. desert fox has large ears ,the better to radiate away body heat

a plant with tough leathery evergreen leaves

small stomata

plants adapted to a dry environment

• plants that have enlarged leaves and stems that contain-water holding tissue
• -Ex. Prickly-Pear Cactus

• water tolerant plant that requires a saturated or semisaturated environment
• -Ex. Mangroves

• plants that grow in or under water
• -Ex. Lily

• organisms can tolerate small range of salinity change
• -Ex. open-ocean organisms

• organisms can tolerate large range of salinity change
• Ex. Coastal-water organisms

salt tolerant species

plants tolerant to calcium limestone

an environment where an organism lives

the combination of role and habitat for a particular species
