Here are the answers to the questions on the worksheet, with a quick explanation for each one.
1. Which is not an example of a salamander's life cycle?
Salamanders are amphibians. They start as eggs in water, hatch into larvae (like tadpoles) with gills, and then grow lungs to live on land as adults. To have babies, they must go back to the water to lay eggs. They do not give birth to live babies like mammals do.
*
Answer: D. has live babies
2. Compare the butterfly life cycle to the grasshopper life cycle? How are they the same?
Looking at the diagrams, both cycles begin at the very top with an egg. While butterflies fly and grasshoppers hop, the thing they share in their life cycle is how they start.
*
Answer: b. Both animals start out as eggs.
3. After a fish egg hatches, it \_\_\_\_\_\_\_\_\_\_.
When a fish egg hatches, a tiny fish comes out. It looks like a miniature version of its parents, just smaller. It does not go through a big shape change (metamorphosis) like a caterpillar turning into a butterfly.

4. Which animal has a life cycle most like a chicken's life cycle?
