Memorandum

Opdrag 11:

  • Leeu
  • Blouwalvis (grootste soogdier)
  • Vlermuis
  • Miervreter en krimpvarkie

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

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:

  • in die see_______________________________________________________
  • tussen voël_____________________________________________________

In economics, a perfect market refers to a theoretical construct where all participants have perfect information, goods are homogenous, there are no barriers to entry or exit, and prices are determined solely by supply and demand. It's an idealized model used for analysis,

What is different between quantity demand and demand?
Shukri Reply
Quantity demanded refers to the specific amount of a good or service that consumers are willing and able to purchase at a give price and within a specific time period. Demand, on the other hand, is a broader concept that encompasses the entire relationship between price and quantity demanded

Economic growth as an increase in the production and consumption of goods and services within an economy.but Economic development as a broader concept that encompasses not only economic growth but also social & human well being.

sir...I just want to ask one question... Define the term contract curve? if you are free please help me to find this answer 🙏

it is a curve that we get after connecting the pareto optimal combinations of two consumers after their mutually beneficial trade offs

In economics, the contract curve refers to the set of points in an Edgeworth box diagram where both parties involved in a trade cannot be made better off without making one of them worse off. It represents the Pareto efficient allocations of goods between two individuals or entities, where neither p
