4. The Life Cycle
The series of stages in form and functional activity through which an organism passes between successive recurrences of a specified primary stage.

5. Life Cycle Facts All organisms go through stages of development.
Environmental conditions such as water, temperature, and light affect the development of organisms.
In most mammals the stages of life go from the fertilized egg, to the fetus, the juvenile, and then to the adult.
Scientists can even describe the life cycle of a star or a plastic bottle.
Even families can have a life cycle. Most families have the parents come together as a unit. They can then have a child. The child becomes an adult. The new adult leaves home, finds a partner, produces offspring and the life cycle begins again.

6. What Are Life Cycles?
The life-cycle of an animal, includes all of the stages from the end of the last generation to the beginning of the next. Life-cycles vary in time depending on the species of animal, and can be as short as just a few weeks for insects, to up to 200 years for sea urchins. Despite the time differences, all animal cycles begin with the growth and development process, which is then followed by reproduction. The reproduction stage in the cycle of life marks the end of the cycle and many animals often die after they have reproduced just once.

7. Starting Life
Most animal species begin life as a single egg cell that is then fertilized by a sperm cell. The growth process varies in speed depending on the species as some animals are born in less than a week of conception, where others can be born nearly two years afterwards. Animals are born in different ways depending on the group as mammals give birth to live young, where birds, fish and reptiles lay eggs which their young hatch out of. In some egg- laying animals such as sharks, the eggs are laid and incubated inside the body of the mother shark, who therefore gives birth to live young.

8. Living Life
Depending on the animal species, some animals live very solitary lives and only meet up with other animals from the same species to mate, where other animal species such as termites and monkeys are very sociable animals and spend their lives in a group. Animals spend their lives hunting for food and water, staying safe and looking for a mate to reproduce with.

9. Amphibians
they are born (either alive from their mother or hatched from eggs)  
they spend their childhood under water, breathing with gills  
they grow into adults and move to the land, breathing with lungs

10. Insects egg: unborn stage.
larva:   young stage -- this is when most of the feeding is done.
pupa:  inactive (no feeding) stage between larva and adult stages.
adult:   final, breeding stage.

11. Butterflies Egg- Unborn stage
Larva- young stage -- this is when most of the feeding is done.
Pupa- inactive (no feeding) stage between larva and adult stages.
Adult- final, breeding stage.

14. Penguins Egg- One or two eggs are laid in the nest
Chick- the baby penguin gets raised to adult hood by both mother and father
Adult- grows up to find a mate

17. Flowering Plants Roots begin to form under the soil.
The stem, leaves and flower bud emerge above the soil.
The plant grows tall, more leaves grow and the bud opens to show the flower.
