Answer Key

#	Answer
1	A life cycle is the series of stages an organism goes through during its life.
2	Examples include a butterfly, frog, plant, or human.
3	A seed begins the life cycle by germinating when conditions are right.
4	The first stage is the egg.
5	The stage after the caterpillar is the pupa, or chrysalis.
6	Germination.
7	Metamorphosis is a major change in body form during development.
8	The tadpole stage comes after the egg stage.
9	A human baby is much larger at birth than a butterfly egg.
10	They help explain how living things grow, develop, and reproduce.
11	Growth is getting bigger, while development is becoming more mature or changing form and function.
12	Scientists study life cycles to understand reproduction, development, and population changes.
13	The final stage is the mature plant stage.
14	A butterfly has complete metamorphosis with very different stages, while a human grows more gradually without a dramatic body change.
15	The main purpose is to produce offspring and continue the species.
16	A frog begins in water as a tadpole and later becomes an adult that can live on land and in water.
17	Different organisms have different evolutionary adaptations and developmental patterns.
18	Temperature, water, light, and soil conditions can help or prevent germination and early growth.
19	It helps farmers know when to plant, care for, and harvest crops for the best results.
20	Living organisms use energy from food or sunlight to support growth, development, and reproduction throughout the life cycle.
