This document discusses the basic needs of humans, animals, and plants. It explains that all living things require water, air, food/nutrients, and shelter. Water is essential for regulating temperature, transporting nutrients, and removing waste. Air is needed for respiration and to obtain oxygen. Food provides energy for activities, growth and tissue repair. Shelter offers protection from dangers, weather, and predators. The basic needs of each organism allow it to carry out vital life processes and survive.

Sebab:
Reason:
BAHAN BUANGAN
WASTE PRODUCTS
- menyingkirkan BAHAN BUANGAN
melalui AIR KENCING & PELUH
- remove WASTE PRODUCTS through
URINE & SWEAT
NUTRIEN
NUTRIENTS
- mengangkut NUTRIEN ke seluruh
tubuh badan
- carry NUTRIENTS to whole body
SUHU BADAN
BODY TEMPERATURE
- mengawal / mengekalkan SUHU
BADAN
- control / maintain BODY
TEMPERATURE

BLOOD CIRCULATION
- melancarkan PEREDARAN DARAH
- improve BLOOD CIRCULATION
Udara
Air
Sebab:
Reason:
BERNAFAS
BREATHE
- DARAH mengangkut OKSIGEN
daripada PARU-PARU ke BAHAGIAN
BADAN LAIN
- BLOOD carries OXYGEN from the
LUNGS to OTHER PARTS of BODY
PROSES PERNAFASAN / PROSES RESPIRASI:
Manusia BERNAFAS:
- MENYEDUT MASUK OKSIGEN
- MENGHEMBUS KELUAR KARBON
DIOKSIDA
BREATHING PROCESS / RESPIRATION PROCESS:
Humans BREATHE:
- BREATHE IN OXYGEN
- RELEASE OUT CARBON DIOXIDE
70% daripada JISIM BADAN terdiri daripada AIR
70 % of BODY MASS is made up of WATER
Perlu minum sekurang-kurangnya 6 – 8 gelas AIR SETIAP HARI
Need to drink at least 6 – 8 glasses of WATER EVERYDAY
Seseorang MUNGKIN akan MATI jika KEHILANGAN
1/5 daripada AIR dalam badan
A person MAY DIE, if he LOSES 1/5 of the WATER in his
body
Seseorang akan MATI jikaTIDAK MINUM AIR selama 2
– 3 hari
A person will DIE, if he DOES NOT DRINK WATER for 2
– 3 days
