What do you remember?

(i) ‘n Ekosisteem word gevorm deur alle lewende organismes wat mekaar en hul omgewing onderling beïnvloed

(ii) lug; water; son en grond

(iii) organisme – materie – energie

(iv) plante (produseerder); ruspes (primêre verbruiker); voëls (sekondêre verbruiker)

(v) perd; olifant

(vi) Karnivore is vleiseters en herbivore is planteters

Leerder afdeling

Inhoud

Aktiwiteit: om te onderskei tussen herbivore, karnivore en omnivore [lu 1.2, lu 2.1, lu 2.2]

3. MAKROVERBRUIKERS

(a) HERBIVORE

Hulle eet saadpeule, gras, blare en groentes. Hulle eet nie vleis nie en jag dus nie. Hulle word egter deur karnivore gejag. Hul liggame is aangepas om by hul leefwyse en eetgewoontes te pas.

Hulle het groot ore en hoor dus besonder goed. Party is gestreep (bv. koedoe, njala, sebra, ens.) om hulself te kamoefleer. Baie karnivore sien net skakerings van grys, swart en wit. Omdat karnivore nie tussen kleure kan onderskei nie, is die koedoe en ander bokke veilig terwyl hulle stil staan wanneer gevaar dreig.

Die meeste planteters kan baie goed sien. Die oë is weerskante van die kop geleë, wat hulle 'n wye gesigsveld gee. Tesame met hulle goeie reuksin, is herbivore (bv. koedoes, sprinkane, springbokke, skape, konyne, hase, ens.) gedurig bedag op gevaar!

Opdrag 11

Skryf 'n kort verslag oor een van die bogemelde diere deur die oë, ore, reukvermoë, kos en vyande te beskryf.

(b) KARNIVORE

Soogdiere vorm die grootste groep karnivore. Dit sluit die katfamilie (wildekatte, leeus, luiperds, tiere, en huiskatte) en die hondefamilie (wolwe, jakkalse, vosse, wildehonde en huishonde) in.

Hulle is normaalweg jagters wat eers hul prooi moet vang voordat hulle dit kan eet. Karnivore hoor en ruik goed en het sterk, spits kake om na die prooi te hap en stukke vleis af te skeur. Die oë is aan die voorkant van die kop geleë, dus kan hulle goed fokus en afstand akkuraat skat. Hulle het ook sterk bene wat hulle in staat stel om vinnig en rats te wees wanneer die prooi gejaag word. Hulle hardloop blitsvinnig oor lang afstande sonder om moeg te word.

Karnivore kom oral voor:

  • op land _________________________________________________________
  • in die see_______________________________________________________
  • tussen voël_____________________________________________________
  • en in die insektewêreld____________________________________________

How bacteria create energy to survive?
Muhamad Reply
Bacteria doesn't produce energy they are dependent upon their substrate in case of lack of nutrients they are able to make spores which helps them to sustain in harsh environments

explain assimilatory nitrate reduction
Esinniobiwa Reply
Assimilatory nitrate reduction is a process that occurs in some microorganisms, such as bacteria and archaea, in which nitrate (NO3-) is reduced to nitrite (NO2-), and then further reduced to ammonia (NH3).
Elkana
This process is called assimilatory nitrate reduction because the nitrogen that is produced is incorporated in the cells of microorganisms where it can be used in the synthesis of amino acids and other nitrogen products
