'N EENVOUDIGE VOEDSELKETTING

Aktiwiteit:

Om 'n eenvoudige voedselketting te verstaan

[LU 1.3]

Om gesond en vol energie te wees, het alle plante en diere voedsel nodig. Plante het ‘n unieke eienskap, en dit is om hul eie voedsel te vervaardig. Hulle doen dit deur sonlig, koolstofdioksied uit die lug, asook water en minerale uit die grond te gebruik.

Alle lewende wesens het voedsel nodig wat deur groen plante gemaak word. Die dele van ‘n voedselketting is soos die skakels in ‘n ketting: as een skakel weg is, is die ketting nutteloos, totdat dit weer reggemaak word. Elke deel van die voedselketting is belangrik vir die voortbestaan van die ekosisteem.

Opdrag:

Die volgende voedselkettings is verkeerd. Maak hulle reg:

mielies, son, boer, eier, hen

Koei, seun, son, gras, melk

Leeu, bok, gras, son

Roofvoël, son, muis, koring

Dit is duidelik wanneer die leerder:

1.1   ondersoek beplan;

1.2   ondersoek uitvoer en data versamel;

1.3       data evalueer en bevindings kommunikeer.
