Markscheme

This question requires “Resource Booklet - May 2019 SL paper 1”, available under the "your tests" tab > supplemental materials.

it does not occupy land (needed for population / housing / wilderness area) / less deforestation;
fewer resources/inputs required / it is cheap/free (if harvested themselves);
there is natural income available (if harvested sustainably)/annual yield from natural capital;
it satisfies cultural preferences;
diverse range of species/food available (within Coral Triangle);
high in nutrients/protein/essential minerals such as iodine;
weather events (droughts/floods/hurricanes) are less likely to destroy food sources;

Accept other reasonable responses.

Do not accept “more carbon stored / improves water quality”.

Do not accept only “provides source of fish/shellfish/profit / rarity of fish / high value of fish / is a healthier food supply / biodiverse ecosystem / easy accessible / no transport cost / is replenishable / increase in diversity of species”.

a.

This question requires “Resource Booklet - May 2019 SL paper 1”, available under the "your tests" tab > supplemental materials.

 

production is more efficient because of less loss of light energy;
it is more efficient because food chain is shorter / more efficient as food is harvested from lower trophic level;
it is more readily harvested because it is less dispersed;
easier to harvest / less dangerous / requires less equipment;
greater diversity of food products/crops / people decide what to grow;
reduces threat to marine habitats from overfishing / reduces damage to marine ecosystems from fishing / reduces overfishing rates / conserving marine ecosystems can make them more attractive for recreational use/tourism;
good growing condition in the area for crop growth / high levels of insolation and rainfall (tropical conditions) in the area promote rapid crop growth;

 

Accept other reasonable responses.

Do not accept “absorbs/stores carbon dioxide / contains large number of nutrients”.

Do not accept only “sell goods”.

Examiners report

The responses for this question were very mixed with popular responses including ‘diverse range of species/food available’ and ‘high in nutrients/protein’.

a.

Overall, this question was poorly answered. A significant number of candidates did not attempt to answer it. A few candidates confused aquaculture with agriculture. Few students stated that production is more efficient as food is harvested from a lower trophic level (less loss of energy).
