"Life Cycle of Other Animals" Animal Life Cycle PPT

Part One: Observing and understanding the life cycles of other animals

The life of silkworms goes through four stages: birth, growth and development, reproduction, and death. Do other animals also go through such a process in their lives? What are the various stages of this process?

Butterfly's life

The lifespan of butterflies varies. The long life span can reach 11 months, while the short life span is only 2 to 3 weeks.

Dragonfly's life

The life of a dragonfly is divided into egg stage → larval stage → adult stage. They do not pupate like butterflies or moths before emerging into adults, but instead metamorphose directly from larvae to adults.

It takes at least a year for a dragonfly larvae to survive in the water, and it takes seven or eight years for a longer period of time to emerge as an adult. The lifespan of a dragonfly is only one-tenth that of a larvae, and can only live for about one to eight months. Despite this, it is considered to be the longest-lived among insects.

Life cycles of other animals PPT, part 2: different life cycles

What are the similarities and differences in the life cycles experienced by the animals we studied above?

Some animals look very different in their infancy and adulthood, changing from one form to another. This change is called metamorphosis.

Many animals in nature go through metamorphosis throughout their lives.

Based on these differences, we classify animals.

Which ones go through metamorphosis in life, and which ones don’t?

What small animals hatch from eggs like silkworms or birds?

Which small animals, like dogs, are directly born from their mothers?

Various animals have their own life cycle, including birth, growth and development, reproduction and death.

The stages that different animals go through in their life cycles are not necessarily the same, nor are the lengths of the cycles.

Some animals undergo metamorphosis throughout their lives, while others remain unchanged in form but change in size.
