Question
Spot as many organisms as possible in the puzzle given in Figure 1.2 by encircling them as shown. Write the names on a sheet of paper and categorise them into autotrophs and heterotrophs. Classify the heterotrophs into herbivores, carnivores, omnivores and saprophytes.
Solution
Autotrophs: rose, mango, bhindi, carrot, banyan, tulsi, ginger, yam
Heterotrophs: elephant, ant, yeast, tiger, mushroom, fox, mice, owl, cow, cow, rabbit, beef, fish, ape
Herbivores: elephant, cow, rabbit, bee
Carnivores: tiger
Omnivores: ant, mice, owl, crow, fox, ape
Saprophytes: mushroom, yeast
Note: Fish can be herbivores, carnivores or omnivores depending on the species.

A unicellular animal P having no fixed shape ingests a food particle by forming temporary finger-like projections Q. The food particle is engulfed with a little surrounding water to form a temporary stomach R inside it. The chemicals S from surrounding cytoplasm enter into R and break down food into small and soluble molecules by chemical reactions. The digested food is absorbed directly into cytoplasm by the process T. The undigested food is thrown out of the body by the rupture of a cell organelle U in a process called V.
