What do the arrows in the food web represent?

The flow of energy within the food web.


List two producers and three consumers in the food web.

Producers = rosebush, oak tree, grass
Consumers = deer, wolf, rabbit, squirrel caterpillar, frog,
sparrow, snake, hawk


Draw one food chain that includes the sparrow.

rose bush –> caterpillar –> sparrow -> hawk
rose bush -> caterpillar -> sparrow -> snake
oak tree -> caterpillar -> sparrow -> hawk
oak tree -> caterpillar -> sparrow -> snake
grass -> caterpillar -> sparrow -> hawk
grass -> caterpillar -> sparrow -> snake

Good Luck
on the Exam!
