Please solve question no.2.

Dear Student,

a) Magnesium metal is present in the Chlorophyll whihc is essential for its proper functioning. Similarly, in hemoglobin, there are 4 iron ions whihc are present. Therefore it is called as heme (iron) and globin. Thus, Haemoglobin: Iron

b) Photosynthesis involves two processes namely light reactions and dark reactions. The light reactions occur in the granum while the dark reactions take place in the stroma of the chloroplast. So, Dark reaction: Stroma

c) Producers - who make their own food. Autotrophs are organims who make their own food. Ex - Plants
Consumers  - who feed on others like animals, so they are heterotrophs (who do make their own food). So, Consumers: heterotrophs

d) During the process of respiration, carbon dioxide is released while oxygen is inhaled (or taken in).
Similarly, in the process of photosynthesis,  oxygen is released (it is a byproduct) and carbon dioxide is used as a raw material for the process. So,  photosynthesis:  oxygen

e) Xylem transports water and minerals in plants, while phloem transports the food materials. So, prepared food: Phloem
