The image displays a diagram titled "Life cycle of a nematode worm". The central circular diagram, labeled "Nematode Worm Life Cycle", illustrates the following stages: An adult worm inside a sheep undergoes Stage 3-5 development within the sheep intestine. Eggs are then dropped in faeces onto grassland. The eggs embryonate in five days. The embryo hatches into Larvae Stage 1, which remains in the faeces. This moults and grows into Larvae Stage 2, also in the faeces. It moults again to become Larvae Stage 3, which leaves the faeces and attaches to grass. A sheep eats the worm, completing the cycle. An additional note states that Stage 3 larvae may survive for up to one year on grass. Definitions are provided for 'Faeces' (solid waste material that leaves the body through the anus) and 'Moult' (remove outer layer of skin in order to increase body size).
Given the complexity of the image, the above description may not be entirely accurate.

The process diagram delineates the life cycle of nematode worms.
Overall, it is a cyclical process, consisting of six stages in which the stage of the nematodes developing within the sheep’s intenstines eventually leads back to itself.
Firstly, developed nematode worm eggs from sheep intensines are dropped onto grassland while they’re still in the sheep’s faeces. Five days later, the eggs embryonate. Then, the worms hatch from the eggs as they remain in the faeces, beginning the first satge of the Larvae. The Larva then grows in size by moulting (stage 2), however still remaining in the faeces. The Larvae moult again, leaving faeces and attaching to grassland, having up to survival span of one year on the grass, marking the end of the Larvae stages.
These worms are eventually consumed by the sheep repeating the cycle.
