h water hcycle, hthe hcarbon hcycle, hthe hnitrogen hcycle, hand hthe hphosphorus hcycle.

h environmental hconditions hlead hto hsimilar hanimal hand hplant hadaptations. hExamples hof
h biomes hinclude htropical hrainforests, hdeserts, hand htundra.
biosphere- h- hANS-All hareas hon, hwithin, hand haround hthe hplanet hEarth hthat hare hcapable hof
h supporting hlife.
Calvin hcycle h(Calvin-Ben h- hANS-son hcycle hor hlight-independent hreaction)- hThe hset hof
h chemical hreactions hthat htake hplace hin hchloroplasts hduring hphotosynthesis. hThe hcycle his
h light-independent hbecause hit htakes hplace hafter hthe henergy hhas hbeen hcaptured hfrom

h atmosphere, hwater, hland, hand hecosystems.

h outside hthe hplasma hmembrane. hBacterial hcell hwalls hare hmainly hbuilt hof hpeptidoglycan,
h although hthey hmay halso hcontain hlipidic hmolecules. hAmong heukaryotes, hplants hand hfungi
h possess hcell hwalls, hmade hof hcellulose hand hchitin, hrespectively.
cellular hrespiration- h- hANS-Use hof hoxygen hto hrelease henergy hfrom hnutrients; halso hcalled
h aerobic hrespiration.
