Life Cycles
Life cycle of a Mammal
Gestation: The first stage of a mammal's life cycle begins with the development of the embryo in the mother's uterus, which is called gestation. During this stage, the embryo receives all the necessary nutrients and oxygen from the mother through the placenta.
Birth: Once the gestation period is over, the mammal is born. The young are usually helpless and dependent on their mother for survival at this stage.
Infancy: During the infancy stage, the mammal grows and develops rapidly. This stage is characterized by frequent nursing and rapid weight gain. The mammal learns to walk, run, and interact with its environment.
Juvenile: As the mammal grows, it enters the juvenile stage. During this stage, the mammal continues to develop and mature physically and mentally. Juvenile mammals may learn social skills and develop hunting or foraging skills depending on their species.
Sexual maturity: Once the mammal reaches sexual maturity, it is capable of reproducing. Mammals may reach sexual maturity at different ages depending on the species.
Adulthood: As the mammal continues to age, it reaches adulthood. This stage is characterized by the ability to reproduce and the completion of physical and mental development.
Aging: As the mammal enters old age, it may experience a decline in physical and mental abilities. The aging process can vary greatly among different mammal species, with some animals living only a few years while others may live for several decades.
Life cycle of an Insect

Egg: Insects start their life cycle as eggs. The eggs may be laid on leaves, in soil, or in water, depending on the species.
Nymph: After hatching, the insect goes through several nymph stages. Nymphs look like smaller versions of the adult insect but lack fully developed wings and reproductive organs.
Adult: Once the insect has gone through all the nymph stages, it reaches adulthood. The adult insect has fully developed wings and reproductive organs and is capable of mating and laying eggs.

Egg: As with incomplete metamorphosis, insects start their life cycle as eggs.
Larva: After hatching, the insect goes through a larval stage. Larvae look very different from the adult insect and often have different feeding habits.
Pupa: After the larval stage, the insect enters the pupal stage. During this stage, the insect undergoes dramatic changes as it develops into its adult form.
Adult: Once the insect has completed the pupal stage, it emerges as an adult. The adult insect has fully developed wings and reproductive organs and is capable of mating and laying eggs.
Life cycle of a Bird
Life cycle of a bird
Egg: The life cycle of a bird begins with the laying of an egg. This egg then undergoes incubation either by its mother bird or in its nest until hatching.
Hatchling: Once the egg hatches, a hatchling emerges. At this stage, they are completely dependent on their mother bird for warmth and protection.
Nestling: After some time has passed, the hatchling hatches into a nestling. At this stage, its mother bird continues to provide warmth and protection while providing extra food and water as the nestling grows rapidly and develops feathers.
Fledging: At around 2-3 weeks old, the nestling becomes a fledgling. It begins to leave its nest and explore its environment while its mother bird continues providing food and protection.
Juvenile: When the fledgling becomes independent and can care for itself, it enters the juvenile stage. During this period, birds continue to develop physically and mentally while learning social skills as well as hunting or foraging strategies specific to their species.
Adult: Once a bird reaches sexual maturity, it becomes an adult. This stage marks the completion of physical and mental development as it has the capacity to reproduce.
Aging: As birds reach old age, they may begin to experience a decline in physical and mental abilities. The rate of aging varies drastically between different bird species; some live only a few years while others may live for decades.
