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.
