SECTION B
Myriapods are a group of arthropods that are commonly found in soil habitats in many parts of the world. Many
myriapods are very small and not easy to identify.
Fig. 6.1 shows four species of myriapod, not drawn to the same scale.
Polydesmus Cylindroiulus Scutigera Scolopocryptops denticulatus punctatus coleoptrata sexspinosus

(c) Mitochondria are cell structures that contain a small quantity of DNA.
Scientists are sequencing the DNA of one particular gene in mitochondria to help identify different
species of many animals including myriapods. The sequences that they find are called ‘barcodes’.
(i) State the part of the cell that contains most of the DNA.
...................................................................................................................................... [1]
(ii) Suggest how DNA barcoding might be useful in the conservation of animals, such as myriapods.

(d) A student found the following information about the feeding relationships between some organisms in a
soil habitat.
Dead organic matter, such as leaves, provides food for bacteria and soil fungi.
Earthworms eat dead leaves.
Many millipedes feed on dead plant matter and also on soil fungi.
Nematodes feed on bacteria and are eaten by springtails.
Centipedes are predators that feed on earthworms, millipedes and springtails.
(i) Draw a food web to show the feeding relationships described above.
[4]
(ii) Describe the roles of the soil organisms in the carbon cycle.
