Study Notes
Life Cycle of Animals
- All living organisms, including animals, undergo a cyclical process known as the life cycle, characterized by stages of birth, growth, reproduction, and death.
- The life cycle ensures the continuation of species and varies significantly among different animals, with some having short lifespans (e.g., fruit flies) while others have long lifespans (e.g., dogs average 12-13 years).
Life Cycles of Egg-Laying Animals
-
Chicken:
- Begins with an egg that has a hard shell for protection.
- The chick hatches and matures into a fully grown chicken, which then lays eggs, restarting the cycle.
-
Frog:
- Frogs lay eggs in water, encased in a jelly-like substance for protection.
- Egg develops into a tadpole, which resembles a fish, breathes through gills, and consumes aquatic plants and insects.
- Undergoes metamorphosis into an adult frog, developing lungs and losing its tail.
Life Cycle of Insects
-
Insects undergo significant transformations during their life cycles, showing different forms from their parents.
-
Butterfly:
- Begins with an egg laid on plants, hatching into a larva (caterpillar).
- Caterpillar grows rapidly, molts its skin multiple times.
- Transforms into a pupa (chrysalis), inside which significant changes occur, eventually leading to the emergence of an adult butterfly.
-
Cockroach:
- Life cycle consists of three stages: egg, nymph, and adult.
- Female cockroach lays 16-50 eggs in an egg case; hatching leads to nymphs, which resemble the adult but lack wings.
- Nymphs undergo several molts before becoming fully developed adult cockroaches capable of reproduction.
-
Grasshopper:
- Starts with eggs, followed by several weeks of molting stages before reaching adulthood.
Animals Giving Birth to Young Ones
- Certain animals, such as mammals (e.g., cats, dogs, horses, and giraffes), do not lay eggs but instead give live birth to their young.
- Human beings are included in this category of mammals that reproduce live offspring.
Life Cycle of Animals
- All living things, including animals, undergo a life cycle, which is a repeating pattern involving stages of growth, change, and reproduction.
- Animals reproduce to ensure the survival of their species, producing young ones that follow a life cycle similar to their parents.
- Life cycles vary in length; for example, fruit flies live for a few weeks, dogs for 12-13 years, and some plants like wheat for a few months.
Life Cycle of a Chicken
- Begins with an egg that has a hard shell, protecting the developing chick.
- The chick hatches, grows to an adult chicken, which in turn lays eggs to continue the life cycle.
Life Cycle of a Frog
- Frogs lay eggs in water, protected by a jelly-like covering.
- Eggs hatch into tadpoles, which resemble fish and breathe through gills.
- Tadpoles undergo metamorphosis, developing hind limbs, forelimbs, and lungs while losing their tails to become adult frogs, which breathe through lungs and have moist skin.
Life Cycle of Insects
- Many insects have life cycles with distinct stages where they do not resemble their adult form, undergoing metamorphosis.
Life Cycle of a Butterfly
- The butterfly lays eggs on plants; these hatch into larvae (caterpillars).
- Caterpillars eat, grow rapidly, and undergo moulting, shedding their skin as they grow.
- Larvae transition into pupae (chrysalis), where they appear inactive but undergo significant internal changes, eventually emerging as adult butterflies.
Life Cycle of a Cockroach
- Proceeds through three stages: egg, nymph, and adult.
- Female cockroaches lay eggs in an egg case containing 16-50 eggs that hatch into nymphs.
- Nymphs resemble adults but lack wings and undergo multiple moults before reaching adulthood.
Life Cycle of a Grasshopper
- Starts with an egg, followed by several weeks where it moults multiple times, and culminates in the adult stage.
Animals That Give Birth
- Examples include cats, dogs, horses, giraffes, and humans, all of which are classified as mammals.
- Such animals do not lay eggs but give birth to live young ones, highlighting a different reproductive strategy in the animal kingdom.

Life Cycle of a Chicken
- Begins with an egg that has a hard shell, protecting the developing chick.
- The chick hatches, grows to an adult chicken, which in turn lays eggs to continue the life cycle.
Life Cycle of a Frog
- Frogs lay eggs in water, protected by a jelly-like covering.
- Eggs hatch into tadpoles, which resemble fish and breathe through gills.
- Tadpoles undergo metamorphosis, developing hind limbs, forelimbs, and lungs while losing their tails to become adult frogs, which breathe through lungs and have moist skin.
Life Cycle of Insects
- Many insects have life cycles with distinct stages where they do not resemble their adult form, undergoing metamorphosis.
Life Cycle of a Butterfly
- The butterfly lays eggs on plants; these hatch into larvae (caterpillars).

- All living organisms, including animals, undergo a repetitive pattern known as the life cycle.
- The purpose of reproduction is to ensure the continuity of species on Earth through a cycle where young ones resemble their parents.
- Life cycles consist of various stages, starting from birth, growth, changes, and reproduction.
- Life cycle duration varies significantly among animals; for instance, fruit flies live for a few weeks, while dogs can live for 12-13 years.
Life Cycle of Egg-Laying Animals
-
Chickens:
- Begins with an egg protected by a hard shell.
- The egg hatches into a chick which develops into an adult chicken.
- Adults produce eggs, restarting the cycle.
Life Cycle of Frogs
- Frogs lay eggs in large clusters (spawns) within water; eggs are jelly-like for protection and respiration.
- The young frog starts as a tadpole, resembling a fish, with gills for breathing and a tail.
- Tadpoles undergo metamorphosis, growing hind limbs first, followed by forelimbs; they lose their tail and develop lungs.
- Adult frogs are insectivorous, breathing through lungs and moist skin.
Life Cycle of Insects
-
Insects exhibit multiple growth stages, some not resembling the adult form.
-
Butterflies:
- Eggs are laid on plant leaves or stems; they hatch into larvae (caterpillars).
- Larvae grow rapidly, undergo moulting, and form a pupa covered by a cocoon.
- Adults emerge after the pupa stage and dry their wings before flying.
-
Cockroaches:
- Life cycle includes three stages: egg, nymph, and adult.
- A female lays eggs within an egg case containing 16-50 eggs that hatch into nymphs.
- Nymphs resemble adults but lack wings and undergo several moults before becoming adults.
-
