a) Autotrophic nutrition - iv) Green plants
Explanation:- Autotrophs are those who can prepare their own food by using carbon di oxide as the sole carbon source and do not depend on other organisms for their nutrition. Green plants posses chrolophyll that provides them the ability to produce their own food by the process of photosynthesis.
b) Heterotrophic nutrition - iii) Deer
Explanation:- Heterotrophs are those who can not prepare their own food and depends upon autotrophs for their nutritional requirements. Deer depends upon grass for its food and hence is a Heterotroph.
c) Parasitic nutrition - I) Leech
Explanation:- Parasite is an organism that depends upon the host for its nutrition i.e. it solely depends upon the host for its food and can not survive without it. Leech depends upon the blood it sucks from the host and thus is a parasite.
d) Digestion in food vacuole- ii) Paramecium
Explanation:- Paramecium is a protozoa. As the food enters its mouth, it forms a vacuole in the cytoplasm and travels through the cell. Enzymes from cytoplasm enter the vacuole to digest the food and after digestion, vacuole shrink leaving the nutrients in the cytoplasm. When vacoule reaches the anal pore, it ruptures, releasing the waste to the exterior.

There are four organisms A, B, C and D. The organism A eats only the flesh of other animals as food. The organism B can eat grains, fruits and vegetables as well as meat and fish. The organism C can make the food itself from simple inorganic substances present in the environment by utilising sunlight energy. On the other hand, organism D eats only plants and their products as food.
