Question

Given figure represents two food chains (X and Y) linked together to form a food web. Identify the types of food chains X and Y and the organism A that interconnects these food chains.

• A. X- Detritus food chain, Y- Grazing food chain, A- Bacterium
• B. X- Detritus food chain, Y-Grazing food chain, A- Detritivore
• C. X- Grazing food chain, Y-Detritus food chain, A- Detritivore
• D. X-Grazing food chain, Y-Detritus food chain, A- Grasshopper

Answer 1

Answer: (C)

X- Grazing food chain, Y-Detritus food chain, A- Detritivore

• 
  
• In X, caterpillar feeds on leaves and is fed by an insectivorous bird.
  
• Since the plant is living and is a producer in the chain X, the food chain X is a grazing food chain.
  
• In the chain Y, the first food source is a dead decaying source which is degraded by A or a detritivore and is connected by a secondary and subsequently tertiary consumer.The chain Y is a Detritus food chain.

So, the correct option is 'X- Grazing food chain, Y-Detritus food chain, A- Detritivore'.
