Kekahi mea aneane hoʻokalakupua e hana i kēlā me kēia hāʻule. He aha kēīa? ʻO kēia kahi hoʻololi o ke kala o nā lau ma nā kumu lāʻau. ʻO kekahi o nā kumulāʻau nani loa:
- maple;
- nut;
- aspen;
- ʻoka.
Kāhea ʻia kēia mau kumulāʻau (a me nā kumulāʻau ʻē aʻe e nalo i kā lākou lau) i nā lāʻau deciduous.
Wao nahele Deciduous
ʻO ka lāʻau deciduous kahi kumulāʻau e ninini i nā lau i ka hāʻule a ulu i nā mea hou i ka puna. I kēlā me kēia makahiki, hele nā lāʻau deciduous i kahi hana e huli ai kā lākou lau ʻōmaʻomaʻo i melemele, gula, ʻalani a me ka ʻulaʻula no nā pule he nui ma mua o ka ʻeleʻele ʻana a hāʻule i ka honua.
No ke aha nā lau?
I Kepakemapa, ʻOkakopa a me Nowemapa hauʻoli mākou i ka loli kala o nā lau lāʻau. Akā ʻaʻole hoʻololi nā lāʻau iā lākou iho, no laila pono ʻoe e ʻike i ke kumu e melemele ai nā lau. Aia kekahi kumu no ke ʻano o ka waihoʻoluʻu o ka hāʻule.
ʻO Photosynthesis ke kaʻina e hoʻohana ai nā lāʻau (a me nā mea kanu) e "hoʻomākaukau i ka meaʻai." Lawe i ka ikehu mai ka lā, ka wai mai ka honua, a me carbon dioxide mai ka lewa, hoʻolilo lākou i ka glucose (kō) i "ʻai" i hiki ai iā lākou ke ulu aʻe i nā mea kanu ikaika a olakino hoʻi.
Kū ka photosynthesis i nā lau o kahi kumulāʻau (a i ʻole mea kanu) ma muli o ka chlorophyll. Hana ʻo Chlorophyll i kekahi mau hana ʻē aʻe; huli i nā lau ʻōmaʻomaʻo.
Āhea a no ke aha e melemele ai nā lau
No laila, inā mau ka lau i ka wela a me ka ikehu mai ka lā mai no ka mea ʻai, hoʻomau ka lau i ka lau i ka lāʻau. Akā ke loli ke kau, ʻoi aku ke anuanu ma nā wahi ulu nā lāʻau deciduous. E pōkole ana nā lā (emi iho ka lā. Ke hiki mai kēia, lilo i mea paʻakikī no ka chlorophyll i nā lau e hoʻomākaukau i ka meaʻai e pono ai e mālama i kona kala ʻōmaʻomaʻo. No laila, ma kahi o ka hana ʻana i nā meaʻai hou aʻe, hoʻomaka ka lau e hoʻohana i nā mea momona a lākou i mālama ai i nā lau i nā mahina mahana.
Ke hoʻohana nā lau i ka meaʻai (glucose) i hōʻiliʻili ʻia i loko o lākou, e hana ana kahi papa o nā hunaola ma ke kumu o kēlā me kēia lau. Spongy kēia mau hunaola e like me ka cork. ʻO kā lākou hana ka hana ma ke ʻano he puka ma waena o ka lau a me ke koena o ka lāʻau. Pani mālie loa kēia puka a "hāmama" a pau nā meaʻai o ka lau i ka pau.
E hoʻomanaʻo: hana ʻo chlorophyll i nā mea kanu a waiho i nā ʻōmaʻomaʻo
I kēia kaʻina hana, ʻike ʻia nā aka ʻokoʻa ma nā lau o nā kumu lāʻau. ʻO nā kala i ʻulaʻula, melemele, gula a me ka ʻalani e peʻe i nā lau i ke kauwela a pau. ʻAʻole ʻike ʻia lākou i ke kau mahana ma muli o ka nui o ka chlorophyll.
Ululāʻau melemele
Ke pau nā meaʻai i ka ʻai, melemele nā lau, huli ʻeleʻele, make a hāʻule i ka honua.
