Mea kanu: He aha kāu e ʻike ai

He mea ola ka meakanu. ʻO nā mea kanu kekahi o nā aupuni nui ʻeono i ka biology, ka ʻepekema o ke ola. He aupuni ʻē aʻe nā holoholona. ʻO nā mea kanu kaulana nā lāʻau a me nā pua. He mea kanu nō hoʻi ʻo Mosses, akā no kahi aupuni ʻokoʻa nā haʻani.

Noho ka nui o nā mea kanu ma ka honua. He aʻa ko lākou ma ka honua, kahi e kiʻi ai lākou i ka wai a me nā mea ʻē aʻe mai ka lepo. Aia ma luna o ka ʻāina kahi ʻōpala a i ʻole ke kumu. Ulu ka lau ma luna. Hoʻokumu ʻia nā mea kanu i nā ʻāpana liʻiliʻi he nui, me kahi nucleus a me kahi envelop cell.

Pono ka mea kanu i ka malamalama o ka lā. ʻO ka ikehu mai ka mālamalama e kōkua i ka mea kanu i kāna meaʻai. He mea kūikawā kona i loko o kona mau lau no kēia kumu, chlorophyll.

He aha nā mea kanu paionia?

ʻO nā mea kanu Pioneer nā mea kanu i ulu mua ma kahi kūikawā. Hōʻike koke ʻia kēlā mau wahi ma muli o ka hili ʻana o ka ʻāina, ka pele pele, ka waikahe, ke ahi o ka ululāʻau, ke hoʻi ka glaciers, a pēlā aku. Hiki ke ʻeli ʻia ia mau wahi i nā ʻauwai hou a i ʻole nā ​​wahi i pae ʻia ma luna o nā pā hale. Pono nā mea kanu Pioneer i nā waiwai kūikawā:

ʻO kekahi hiʻohiʻona ka laha ʻana o nā mea kanu paionia. He ʻano maikaʻi nā ʻanoʻano e hiki ai iā lākou ke lele mamao me ka makani, a i ʻole e lawe ʻia e nā manu a hoʻokuʻu ʻia i loko o ka lepo.

ʻO ka lua o ka maikaʻi pili i ka frugality me ka lepo. ʻAʻole pono e koi ʻia kahi mea kanu paionia. Pono ʻo ia e hele a kokoke a i ʻole ka loaʻa ʻole o ka momona. Loaʻa kēia ma ka loaʻa ʻana o ka mea hoʻomomona mai ka lewa a i ʻole mai ka lepo me kekahi mau bacteria. ʻO kēia ke ʻano o ka hana a ka poʻe kahiko.

ʻO nā mea kanu paionia maʻamau he birch, willow, a i ʻole coltsfoot. Eia nō naʻe, hāʻule nā ​​lau o nā mea kanu paionia a make paha ka mea kanu holoʻokoʻa ma hope o kekahi manawa. Hoʻokumu kēia i ka humus hou. ʻAe kēia i nā mea kanu ʻē aʻe e laha. E make mau nā mea kanu paionia ma hope o kekahi manawa.
