1.There are many abiotic factors that affect the rate of photosynthesis in terrestrial plants. Wheat is an important cereal crop in many parts of the world. Wheat seedlings were grown at three different concentrations of carbon dioxide (in parts per million) and the rate of photosynthesis was measured at various light intensities.
(a)Describe the relationship between the rate of photosynthesis and light intensity for wheat seedlings grown at a CO2 concentration of 500 ppm.
(2)
(b)Outline the effect of CO2 concentration on the rate of photosynthesis of the wheat seedlings.
(3)
(c)The normal atmospheric concentration of CO2 is 370 ppm. Deduce the effect of doubling the CO2 concentration to 740 ppm on the growth of wheat plants.

2.Copepods are very small crustaceans and an important component of plankton in the Arctic sea ice. The distribution of copepods, which feed on microalgae, can be related to the food and predators. The biomass of microalgae was measured and the concentration of chlorophyll a was calculated. The graphs below show how the concentration of chlorophyll a and copepods change with depth.
