What do the arrows represent in a life cycle model?

• The arrows represent a major event in the life cycle of each bird

• The arrows represent a certain amount of time passing.

• The arrows don’t represent anything in the model.

Imagine that there is pollution in the pond water where frogs live that prevents the eggs from hatching into tadpoles. Use your model of the frog’s life cycle to explain what would happen to the frogs over time.

• The frogs will all die over time. If there are no more tadpoles, then the life cycle will not continue.

• The frogs will leave and live in the grass together. They will change their color and become camouflage.

• The frogs will adapt to these changes by growing wings and will fly away
