Worked Solution & Example Answer:The photograph shows a pupil with a sweep net - Junior Cycle Science - Question c - 2009
Step 1
(i) Name a second item of equipment used to collect small animals for identification.
Answer
One suitable second item of equipment that can be used to collect small animals for identification is a 'pooter'. This is a small device that allows the collection of small invertebrates without harming them.
Step 2
(ii) Draw a labelled diagram, in the box provided, of the item that you have named in (i) above.
Answer
In the box provided, draw a diagram of a pooter. Make sure to label the following parts:
- Mouthpiece: where the user sucks in air to create a vacuum.
- Collection chamber: where the collected specimens are held.
- Tubing: connects the mouthpiece to the collection chamber.
Step 3
(iii) Describe how to use the item that you have named and drawn.
Answer
To use a pooter, follow these steps:
- Place the collection chamber over the area where the small animals are located, making sure it is well positioned to capture them.
- Suck gently on the mouthpiece; this creates a vacuum that draws the small animals into the collection chamber.
- Once sufficient animals are collected, cover the opening of the collection chamber to prevent them from escaping.
- Transfer the collected specimens into a suitable container for further examination.
Step 4
Give two reasons why the groups of organisms living together can vary greatly from one part of a habitat to another.
Answer
One reason is the presence of different types of vegetation, which can support various species of organisms. Two reason is the availability of resources such as food and water, which can differ significantly in different parts of a habitat.
