Question 1

What are the main stages in the life cycle of a butterfly?

Accepted Answer

The life cycle of a butterfly consists of four main stages: egg, larva (caterpillar), pupa (chrysalis), and adult butterfly. This process is known as metamorphosis. Each stage has distinct characteristics and purposes, such as growth during the larva stage and transformation during the pupa stage.

Question 2

How does the life cycle of a frog differ from that of a butterfly?

Accepted Answer

The life cycle of a frog includes the stages of egg, tadpole, tadpole with legs, froglet, and adult frog. Unlike butterflies, frogs undergo incomplete metamorphosis, meaning they do not have a pupal stage. The transition from tadpole to adult frog involves gradual changes, such as the development of legs and the absorption of the tail.

Question 3

Why is understanding animal life cycles important in the Singapore Curriculum for Science?

Accepted Answer

Understanding animal life cycles is crucial as it helps students grasp the concept of biological cycles and the continuity of life. It also fosters an appreciation for biodiversity and the interdependence of organisms. In the Singapore Curriculum, this knowledge supports broader scientific literacy and critical thinking skills.

Question 4

What role does the environment play in the life cycle of some animals?

Accepted Answer

The environment plays a significant role in the life cycle of animals by providing necessary resources such as food, water, and shelter. Environmental factors like temperature, humidity, and habitat availability can influence the timing and success of each life cycle stage. For example, the availability of water is crucial for amphibians like frogs during their breeding season.

Question 5

Can you explain the concept of metamorphosis in the life cycle of some animals?

Accepted Answer

Metamorphosis is a biological process in which an animal undergoes a significant change in form and structure during its life cycle. This process is common in insects like butterflies and amphibians like frogs. Metamorphosis allows these animals to adapt to different environments and ecological niches at various stages of their lives, enhancing their survival and reproduction.
