Adaptions And The Environment Flashcards
adaptions
characteristics which increase an organisms chance of survival in its environment
desert animals save water and keep cool by… 4
- large surface area compared tovolume let’s them lose more body heat
- lose less water my producing small concentrated urine and little sweat
- thin layersof body fat and thin insulating coats
- sandy colour
artic animals reduce heat loss by..
- small surface area compared to volume reduces heat lose
- well insulated hairy coats greast fur sheds water
- white fur camo
desert plants3
plants lose water vapour from thier leaves so some dplants have spines
water storage tissue
shallow but extensive roots
extremophiles
bacteria adapted to live in hot volcanic vents or very salty lakes
competition plants 4
light space water minerals from soil
competition animals4
territory food water and mates
causes of environmental change (living)4
(change in)
- occurence of infectious diseases
- number of predators
- number of prey/food sources
- number/types of competitors
causes of enviromental change (nonliving)3
change in..
average temp
average rainfall
levelcof air or water pollution
how environmental change affects organisms
population size increase
population size decrease
population distribution change
living indicator of air pollution
lichen are sensitive to the concentration of sulfur dioxide in the air
living indicator of water pollution
mayfly larvae sensitive to concentration of dissolved oxygen in the water
satellites
non living indicator used to measure temperature of sea surface and the amount of snow cover
automatic weather stations
tell us the atmospheric temperature at various locations
