"The Life Cycle of Other Animals" Animal Life Cycle PPT Courseware

The time of the life cycle is the lifespan of this animal.

Changes in living environment factors such as climate, food, and enemies will have a greater impact on the lifespan of animals.

Water pollution – fish kills

Therefore, we must pay attention when consulting the data. Try to use data under artificial breeding conditions.

Knowledge: Metamorphosis

During the growth and development process of some animals, their juvenile and adult stages look very different, changing from one form to another. This change is called metamorphosis.

Notice:

Many animals in nature go through metamorphosis throughout their lives. For example, toads, do you know any other animals that undergo metamorphosis in their life cycle?

What is the biggest difference in their life cycles?

Chickens hatch from eggs. Simply put, they are oviparous.

Sheep are born directly from their mothers, which is simply called viviparous.

Let's classify animals according to this

do you know?

1. What stages do silkworms, pandas, flies and other animals go through in their lives?

2. Why do animal species not become extinct as individuals age and die?

Summarize

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.

Some animals hatch from eggs (oviparous), and some are born directly from their mothers (viviparous).
