What are the basic stages in most animal life cycles?
AEgg, baby, death
BBirth or hatching, growing up, becoming an adult, having babies
CBorn, eating, sleeping
DBaby, playing, working
Most animal life cycles follow these stages: the animal is born or hatches from an egg, it grows up (getting bigger and learning skills), it becomes an adult, and it can have babies of its own. Those babies start the cycle again.
Question 2 True / False
Most animals are born live like humans.
TTrue
FFalse
Answer: False
Many animals hatch from eggs instead of being born live. Birds, reptiles, fish, amphibians, and insects all lay eggs. Mammals are the main group that gives birth to live babies, though even a few mammals (like the platypus) lay eggs.
Question 3 Short Answer
Why is an animal's life cycle drawn as a circle instead of a straight line?
Think about your answer, then reveal below.
Model answer: Because when an adult animal has babies, those babies grow up and have their own babies, starting the cycle over again. It keeps repeating across generations.
A life cycle is a circle because it does not really end. The adult has babies, those babies grow into adults, and those adults have babies. Each generation repeats the same stages. Drawing it as a circle shows that life continues from one generation to the next.
