Nature chaka chilichonse ali kuti azolowere kusintha kubwera kwa nyengo. Mfundo imodzi yokha - ndi m'tchire mu nthawi iliyonse otere kutaya umoyo, kuwala, timadziti, akusandutsa nyanja lina mdima ndi udzu lopuwala. Mkubwela kwa nyengo ya mvula mofulumira kwambiri moti anayamba kusintha malo kuti ena masiku ochepa chikhalidwe akukhala kwathunthu uja. Ngati Tikayerekeza zithunzi m'tchire isanafike nthawi ya mvula ndipo patapita mlungu mvula, kupeza kufanana awo, silidzakhala Lofewa.

The zomera za m'tchire ndi

Pa wakuda Africa zomera lililonse m'tchire - ndi mitundu yonse ya acacias, mafuta, malambe m'mayiko, lofiry lanceolate, dum-kanjedza njovu udzu, anizofilly, zosiyanasiyana udzu. Zodabwitsa ndizakuti, otsiriza kuposa ena ndinazolowera zikhalidwe za kusintha nthawi zonse chinyezi ndi kutentha zinthu. Ndipotu, ngati nthawi ya chilala, mitengo xerophytes akhoza kungoyankha kutaya masamba ndi kuima mu mawonekedwe izi pokonzekera nyengo yatsopano yonyowa, zimakhala zovuta kwambiri kuti apulumuke zitsamba. Ngakhale chikhalidwe wakhala kuwasamalira kukhala imawonongeratu pa chivundikiro savannah udzu. Mu oimira monga chimanga la African zomera acheya masamba, yopapatiza ndi wovuta ndipo ndi sera zosagwira ❖ kuyanika, zomwe zimasunga chinyontho maselo.

The zomera za savannah ndi

Anthu ambiri amadabwa ndi chidwi steppe m'tchire African. Nyama pa malo ake otsegula amapezeka ambirimbiri. Iwo ali pano chifukwa chodabwitsa chilengedwe cha kusamuka, amene kugwirizana ndi kusintha kutentha pa Dziko Lapansi. Panthawi ina, mamilioni a zaka zapitazo, kontinenti chidafundidwa chonse mwa nkhalango okha nyengo amakhala pang'onopang'ono drier, limene mbali yaikulu ya nkhalango zinafa, pamene mu malo awo anali minda amene inamera zomera busa, ndi mitengo lotseguka. Zimenezi, anali zikamera wa mitundu yosiyanasiyana latsopano la nyama zomwe anali kufunafuna zinthu zabwino kwa ang'onoang'ono.

Choncho, kukhala steppe African. Choyamba anatuluka akadyamsonga nkhalango, njovu anakakhala kumbuyo kwawo zosiyanasiyana mitundu ya anyani, antelopes ndi ena herbivores.
