What is a life cycle? A life cycle is the stages that occur in animals lifetime. A life cycle is a circle that has no end, one life ends and one always begins. Some animals go through different stages as they mature. Learn how amphibians, insects, birds, mammals, and human develop.
The Life Cycle of Human Being
There are four stages of human life cycle - babyhood, childhood, adolescence and adulthood.
Baby
Babyhood is the first stage in the life cycle of the human. Babies are born after spending 9 months developing in their mother womb. When they are born they have to be fed and cared for by their parents. They begin to develop teeth at 5 months. At around 1 year, babies begin to walk but they are still very dependent on their parents.
Children
During childhood, a child can walk, run, talk and feed himself/ herself but it is still dependent on his/ her parents.
Teenagers
Children become teenagers at the stage of adolescence. During this time, boys and girls begin to develop into adults.
Adults
People reach adulthood at the age of 18. Adults do not grow anymore.
The Life Cycle of A Butterfly
Butterflies have a "complete" life cycle. This means that there are four separate stages - egg, larva (caterpillar), pupa and lastly adult butterfly.
The female butterfly attaches the egg to leaves or stems of plants. The caterpillar (or larva) is the long, worm- like stage of the butterfly. The pupa is the transformation stage within which the caterpillar tissues are broken down and the adult insects structures are formed. The adult is colourful butterfly usually seen. The adults undergo courtship, mating, and egg-laying.
The Life Cycle of A Frog
Frogs go through four stages in their life: egg, tadpole, young frog(froglet), and adult.
Life Cycle of A Frog
Frogs lay many eggs. The eggs will hatch. The tadpoles consists of gills, a mouth, and a tail. By 12 weeks, the tadpole looks like a miniature version of the adult frog. By between 12 to 16 weeks, the frog has completed the full growth cycle.
The Life Cycle of A Chicken
The stages of the chicken's life cycle are egg,chick and chicken.
A hen lays eggs in a nest. The egg's hard shell protects it while it grows. After 21 days, the chick hatches out of the egg. The chick likes to eat seeds, bugs and worms. Chicks are fully grown into chickens in six months.
The Life Cycle of Mosquito
The mosquito goes through four separate stages of its life and they are as follows: egg, larva, pupa and adult.
Eggs are laid one at a time and they float on the surface of water. Most eggs hatch into larvae within 48 hours. Larva lives in the water and come to the surface to breathe. The pupa stage is a resting, non0feeding stage. This is the time the mosquito turns into an adult. The newly emerged adult rests on the surface of the water for a short time to allow itself to dry and all its parts to harden before it can fly.
