Which of the following models shows the flow of energy in a woodland ecosystem? select the two correct answers.

Question

sun ------ caterpillar ---- bird ----- hawk

sun ------ hawk ----- bird ---- caterpillar
sun ---- tree ---- grass ---- mouse
sun ---- tree ---- caterpillar --- bird
sun -- grass --- mouse -- owl

Answer 1

The two models that show the flow of energy in a woodland ecosystem are:

1. sun ---- tree ---- caterpillar --- bird
2. sun -- grass --- mouse -- owl

These options correctly illustrate the flow of energy from the sun to producers (like trees or grass), then to primary consumers (like caterpillars or mice), and finally to secondary consumers (like birds or owls). The other options do not represent typical energy flow in a woodland ecosystem.
