It was hypothesised that the worms fed avocados will experience the highest mass gain as fats have the highest energy per gram 37.7kj compared to proteins and carbohydrates 16.7kj.The hypothesis was refuted as the worms fed tofu (protein) had the largest mass increase (35.44%)this was unexpected but was expected have the second highest mass gain as not only does it have the same calories per gram as carbohydrates it also is used in the repair and growth of muscles. See graph 1. The worms fed avocado had a percentage mass increase of 31.84% which was the second largest amount of mass gain. The worms fed avocados were expected to have the most mass gain as it has almost double the amount of calories per gram than carbohydrates and protein. The …show more content…
The first anomaly was in rice trial 2 see table 2. This anomaly had a significant loss of weight this anomaly occurred as one of the four worms had died therefore was not weighed causing the loss of weight therefore this result was excluded from the final calculation. The second anomaly was in tofu trial 1 were there was an insignificant mass gain see table 2. This anomaly may have occurred as the worms were not washed before being weighed causing dirt to be carried with them increasing their weight. This worm may have been on the clean news paper and rubbed of majority of the dirt on it causing it to have an insignificant amount of mass gain. This result was excluded from the final calculation. A error in the experiment can be seen in the second rice trial, the trial has a large loss of mass see table 2. This error was caused by a worm dieing rendering the data unusable. This was caused as the rice was uncooked, as the rice was uncooked it would absorb the water in the soil causing the worms to struggle and potentially die as one did. As water was not added to the compost bins throughout the experiment the worms living in the rice bins would have slowly lost moisture.To prevent this error in a future repeat of this experiment the rice would be cooked and small amounts of water added every second day. By cooking the rice the rice will absorb less water and be able to be broken down. Also adding water will prevent a
