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, grassConsumers = deer, wolf, rabbit, squirrel caterpillar, frog,

sparrow, snake, hawk

Draw one food chain that includes the sparrow.

rose bush –> caterpillar –> sparrow -> hawkrose bush -> caterpillar -> sparrow -> snakeoak tree -> caterpillar -> sparrow -> hawkoak tree -> caterpillar -> sparrow -> snakegrass -> caterpillar -> sparrow -> hawkgrass -> caterpillar -> sparrow -> snake

Good Luck on the Test!
