Aim: classify the different kinds of living beings into

heterotrophs and autotrophs, and distinguish

among different levels of heterotrophs .

Instructions:the teacher makes a set of

cards with different kinds of living

beings; each student choose a card.

The students will group them like in the

diagram on the left, with all the

producers in the centre and the

consumers arranged in rings (each ring

represents a level).

Final questions:

● IS SOMEONE LEFT BEHIND?

WHAT KIND OF LIVING BEINGS

FUNGI ARE?

● ARE THERE ANY LIVING

BEINGS THAT CAN BE IN MORE

THAN ONE LEVEL?
