Concept	Remember
Living organisms	Show integrated life processes such as nutrition, respiration, growth, response and reproduction.

Mosquito	Egg → Larva → Pupa → Adult.
Frog	Spawn → Tadpole → Froglet → Adult.

Dry fallen leaf — Non-living

Section H

Mosquito: Egg → Larva → Pupa → Adult
Frog: Spawn → Tadpole → Froglet → Adult frog
Plant: Seed → Germination → Seedling → Adult plant → Flower → Fruit/seed formation → New seeds

Case Study 1

Pot A is most likely to germinate successfully because the seeds receive suitable water and air. Flooding can reduce oxygen availability, while dry seeds lack sufficient water.

Case Study 2

Stagnant water provides a suitable place for mosquitoes to lay eggs and for immature stages to develop. Removing stagnant water and using appropriate approved mosquito-control measures can reduce breeding.

Case Study 3

The frog eggs are called spawn. Tadpoles are adapted to aquatic life and use their tail for swimming. During development, legs appear and the tail is gradually absorbed as the young frog changes into an adult.

Challenge Questions

Answers should clearly explain the relationship between life processes, environmental conditions and survival. Award marks for scientifically correct reasoning expressed in the student’s own words.
