All living things in this world will experience changes in body shape as they age. This process of change is known as the life cycle.

Between humans, animals and plants have different stages of the life cycle. The life cycle of animals is also known as the metamorphosis process. Animals have 2 types of life cycles, namely life cycles with metamorphosis and life cycles without metamorphosis.

If you want to know more about the life cycle in animals, see the full explanation in the discussion below.

Definition

The animal life cycle is a process of changing the shape of an animal’s body throughout its life. This process starts from still in the form of eggs to adults.

Changes in body shape in these animals are caused by cell growth that occurs over time. The speed of growth in animals can be influenced by the food that the animal eats.

When viewed from their body shape, animals have 2 forms of life cycles, namely life cycles with metamorphosis or life cycles without metamorphosis, the following is an explanation.

Metamorphosis

Metamorphosis is divided into complete metamorphosis and incomplete metamorphosis. Complete metamorphosis is a change in the form and function of the body that is very different (noticeable) during the stages of growth. Metamorphosis is not perfect is a change in the form and function of the body that is not too different (not conspicuous) during the stage of growth.

Complete metamorphosis

Complete metamorphosis is a form of metamorphosis process that undergoes and passes through four stages, including egg, larva, pupa, nymph, imago. Animals that undergo complete metamorphosis include butterflies, mosquitoes and frogs.

Incomplete metamorphosis

Complete metamorphosis is a form of metamorphosis process that only undergoes and passes through three stages, namely from egg to nymph/larva and finally to adult.

In the type of animal that undergoes an imperfect metamorphosis process, the young body shape of this animal tends to be similar to its parent, it’s just that there are parts of the body that are not fully formed.

There are several types of animals that undergo this metamorphosis, including dragonflies, grasshoppers, crickets and cockroaches.

No Metamorphosis

The life cycle of animals without undergoing metamorphosis is a life cycle in which there are usually no stages in the process of animals becoming larvae or pupae.

If the animals that undergo complete metamorphosis are mostly insects, the animals with incomplete metamorphosis are mostly poultry and animals that reproduce by giving birth.

Animals that undergo a life cycle without metamorphosis include chickens, cats, cows, goats and fish.
