The position of sea cucumbers in the marine benthic food web and how their position may affect the net primary production through this particular ecosystem. Given: Sea cucumbers feed or graze on organic matter (marine sediments). Introduction: Food web is an interconnection between various different food chains. In nature, food chains do not occur in isolation and are always in conjunction with other food chains. Net primary production is a measure of the amount of carbon that is uptaken by organisms after accounting for the loss through respiration. Sea cucumbers play a very important role in the marine food web. Their position also contributes greatly to the net primary production in the marine ecosystem.

The position of sea cucumbers in the marine benthic food web and how their position may affect the net primary production through this particular ecosystem.

Net primary production is a measure of the amount of carbon that is uptaken by organisms after accounting for the loss through respiration. Sea cucumbers play a very important role in the marine food web. Their position also contributes greatly to the net primary production in the marine ecosystem.

Expert Solution & Answer

Explanation of Solution

Sea cucumbers eat the marine sediments that get accumulated in the marine ecosystem. They clear out various organic materials, such as plankton, algae, and bacteria, that would otherwise grow in numbers unchecked and decrease the productivity of the system. They also get preyed on by other species like the leatherback sea turtle and different types of fishes. Thus, it both acts as a recycler of nutrients and as a food source for other species.

Thus, this position of sea cucumber in the food web is essential for the greater productivity in the ecosystem. If sea cucumbers were to get extinct, it would greatly impact the net primary production of that ecosystem. Without sea cucumbers, a food source for the other species would be missing. The algae, plankton, and bacteria would also grow unchecked and eventually cause hypoxia, which would lead to a decrease in the net primary production.

Conclusion

Therefore, it can be concluded that sea cucumbers occupy an important position in the marine food web and their absence would lead to a decrease in the net primary production.

A sample of blood was taken from the above individual and prepared for haemoglobin analysis. However, when water was added the cells did not lyse and looked normal in size and shape. The technician suspected that they had may have made an error in the protocol – what is the most likely explanation? The cell membranes are more resistant than normal. An isotonic solution had been added instead of water. A solution of 0.1 M NaCl had been added instead of water. Not enough water had been added to the red blood cell pellet. The man had sickle-cell anaemia.

With reference to their absorption spectra of the oxy haemoglobin intact line) and deoxyhemoglobin (broken line) shown in Figure 2 below, how would you best explain the reason why there are differences in the major peaks of the spectra? Figure 2. SPECTRA OF OXYGENATED AND DEOXYGENATED HAEMOGLOBIN OBTAINED WITH THE RECORDING SPECTROPHOTOMETER 1.4 Abs < 0.8 06 0.4 400 420 440 460 480 500 520 540 560 580 600 nm 1. The difference in the spectra is due to a pH change in the deoxy-haemoglobin due to uptake of CO2- 2. There is more oxygen-carrying plasma in the oxy-haemoglobin sample. 3. The change in Mr due to oxygen binding causes the oxy haemoglobin to have a higher absorbance peak. 4. Oxy-haemoglobin is contaminated by carbaminohemoglobin, and therefore has a higher absorbance peak 5. Oxy-haemoglobin absorbs more light of blue wavelengths and less of red wavelengths than deoxy-haemoglobin
