Biology 2.6 Describe diversity in the structure and function of animals

Sites for revision

S-Cool!: Biology AS & A2 level
This website provides information about many biological topics. The topics relevant to this standard include nutrition and digestion, transport, support and movement, sensitivity and coordination, excretion, gas exchange, and reproduction. Suitable for NCEA level 2.

Fish – a quick course in ichthyology
This site has some useful material on fish structure and function. It includes biological processes such as transport of materials, reproduction, movement, and sensitivity. It enables fish to be used to illustrate diversity in animal structure and function.

General anatomy of the ruminant digestive system
This website has a concise and easy-to-read description of the ruminant’s digestive system.
http://edis.ifas.ufl.edu/DS061

Digestive anatomy in ruminants
This website has information on the ruminant digestive system and, if you use the digestion index at the top, it will also give a comparison to avian (bird) digestive system. This helps for contrast of diversity of structure and function.

Insect physiology – digestive and excretory systems
This website provides a diagram and information on the digestive and excretory systems of insects. It has links which explain each part of the process in greater detail and is useful for this achievement standard.

Bird digestive system – food and feeding habits
This website has a lot of information and short YouTube videos presenting information on the way birds feed and digest.

The insect ‘heart’
This website contains a simple, labelled diagram and information on the way the insect moves haemolymph around its body.

Tracheal systems
This website has diagrams and information about gas exchange in insects.

Insect organization – structure and function
This website contains information and animations about insects. To view each animation, click on ‘scene menu’ on the bottom left of the animation. The notes to accompany are found on the web page.
