"But the ants will eat them!"
"The ants won't eat them. Ants don't eat other bugs."
"Then what do they eat?"
"They eat the same food you eat. They're gatherers. That means they walk around collecting all the crumbs you drop, and then they take them home to share with their family."
"No. There are worker ants who take everything to the queen."
"There is a queen--you're so smart, Meg. The worker ants collect all the food and take it to the queen, and she makes sure everybody gets some. It's like how Dad goes to work and earns money. Then Mom uses the money to buy food, and she cooks it and makes sure you guys all get some."
Jacob (3) joins the conversation: "Where are the ovens?"
"The ants' ovens? They don't have ovens. They go around picking up your crumbs, so they are eating the food that has already been cooked for you. They don't need ovens. Now come in and leave the bugs outside."
"But the ants will eat my rolly pollies!"
