Summative Practice Chapter 10 – Question 3 & 4 (Form 5 Biology Textbook Exercise and Answer)

Question 3:
The Malayan tiger is an animal facing the threat of extinction in Malaysia. Currently, the number is dwindling to less than 200 throughout the whole country. These animals that can be sold at a high price in the international markets have become the target of illegal hunters.

(a) State the physical characteristics of a Malayan tiger.

(b) Explain how the extinction of the Malayan tiger will affect the stability of the ecosystem.

(c) Other than illegal hunting, predict other factors that may contribute to the extinction of the Malayan tiger.

(d) What are the steps of preservation and conservation that can be done by the Department of Wildlife and National Parks (PERHILITAN) in order to overcome the extinction of Malayan tigers?

Physical characteristics of Malayan tiger: have reddish or rusty-brownish furs, and grey, brown or black stripes on the body.

Malayan tiger extinction causes the dynamic stability of an ecosystem to be affected. Tigers are predators; their absence causes the food chain to be affected. Excess populations of the other predators will cause the extinction of smaller animals.

Factors causing the extinction of Malayan tiger:
• Extensive deforestation for development and agriculture causes the natural habitats of Malayan tigers to destroy.
• Lack of food sources due to extensive hunting activities towards Malayan tigers’ food sources.

Steps of preservation and conservation of Malayan tigers:
• Implementing the Wildlife Protection Act 1922
• Gazetting forest reserves for maintaining the habitats of tigers.
• Providing a breeding facility for the tigers in zoo to increase the population of tigers.

Question 4:
The practice of 5S, sisih (separate), susun (arrange), sapu (sweep), seragam (uniform) and sentiasa amal (always practice) are practices taken from the Japanese culture with the objective of enhancing a better workplace in an organisation. As an employee, would you carry out these practices? Give your reasons.

Yes, I agree.
• Separating (sisih) practice can isolate and determine the things that are needed and unneeded. Unneeded things will be disposed off. This ensures a tidier and safer workplace.

• Arranging (susun) practice enables to label, arrange and store things or documents neatly, easier to be taken and keep them at their respective places again. Working operation becomes more systematic and in order.

• Sweeping (sapu) practice, wiping and cleaning the workplace neatly so that there are no dusts and dirt at the surrounding workplace. This ensures a safer and cleaner workplace.

• Uniform (seragam) practice ensures the workplace always in order at all times so that work operation becomes more efficient.

• Always practice (sentiasa amal) able to train the workers to practice this system continuously so that it becomes a quality habit and culture in the organisation.

• These practices are one of the strategies of sustainability development.
