Spheres of the Earth :
·
biosphere part :
of earth that supports life
life
·
hydrosphere bodies of : water that contain
·
atmosphere :
ar around earth
·
Ilthosphere :
the earth itself
parts ofo n Ecosystem
ecosystem natural unit of :
all blotic factors with the abiotic factors
1 .
Physical Factors
9) Light
green plants need it to photosynthesise ; phototropism-curve towards sun to get light
·
b) temperature
·
change in temp .
between day a
night + seasons influences organisms a adaptations
How To Affects Animals
·
ectothermic (cold-blooded) animals
activity is dependent T
-
on
-cold temps slow their metabolic ratel bodyTo
-very low temp -hibernation
, they
temp a metabolic rate are active
high temps. raise their body
·
end othermic (wom blooded) animals
-constant temp ,
independent of outdoor temp .
animals either (move to wormer crea) hibernate Winter keep worm aestivate-hide from Sun
migrate or in or
:
-
desert animals are nocturnal :
keep cool
How T Affects Plants
·
deciduous trees :
shed all leaves a become dormant in winter
·
annuals live for :
I season
,
then die (they leave seeds to reproduce)
·
perineals grow from :
bulbs
,
bloom in spring a die off in winter (come back in spring)
Factors that Affect T
·
Latitude :
distance from equator
altitude heighta level
:
·
sea
·
aspect
:
slope direction
·
proximity to water bodies :
cold us wom current
c) Water
energy for water cycle comes from Sun
