The document describes the steps of an experiment conducted by students to study the effects of food availability on garden snail populations in different school areas using a mark-recapture technique. The students captured and marked garden snails from study sites and recorded data on recaptures, which was then analyzed to estimate and compare snail population sizes between the sites.

SULIT 2 4551/3 Answer all questions Jawab semua soalan 1. The population distribution of an organism is influenced by the changes in the biotic and abiotic factors. A group of students carried out an investigation to study how biotic factor such as food availability affects the population of garden snail in different school area using the method of capture, mark, release and recapture technique . Penyebaran populasi organisma dipengaruhi oleh perubahan faktor-faktor biotik dan abiotik. Sekumpulan pelajar telah menjalankan kajian mengkaji kesan faktor biotik seperti bekalan makanan ke atas populasi siput babi dalam dua kawasan sekolah yang berbeza dengan menggunakan kaedah tangkap, tanda, lepas dan tangkap semula . These were the steps that has been carried out. Berikut adalah antara langkah-langkah yang telah dijalankan . Step 1 : An area of study with 2500m2 in the school field and school garden are selected. Satu kawasan kajian seluas 2500m2 di kawasan padang dan kebun sekolah dikenalpasti. Step 2: Garden snails are captured randomly from each site and the number of garden snails captured is recorded. Sejumlah siput babi telah ditangkap secara rawak dari kedua-dua kawasan dan dicatatkan bilangannya. Step 3 : Garden snails that have been captured are marked with a small dot of Indian ink on their shell and released into the same location where they were found. Siput babi yang telah ditangkap, ditanda sedikit dengan dakwat India di atas cengkerangnya dan kemudiannya dilepaskan semula ke dalam habitat asal. Step 4 : After 4 days, a second captured is made at random from the same study area. Selepas 4 hari, tangkapan kedua dibuat secara rawak dari kawasan kajian yang sama . Step 5 : The total number of garden snails and the number of marked garden snails are recorded. Jumlah bilangan siput babi dan bilangan siput babi yang bertanda dalam tangkapan kedua direkodkan. Step 6 : The population size of garden snails at school field and school garden are estimated. Saiz populasi siput babi di kawasan padang dan kebun sekolah dianggarkan. 4551/3 © 2011 Hak Cipta JPM [Lihat sebelah SULIT
