Consider the following differences between Grazing food chain and Detritus food chain:

  1. While grazing food chain begins with green grasses at first tropic level, detritus food chain begins with dead decay of organic matter
  2. While grazing food chain adds energy to the ecosystem, detritus food chain consumes energy from ecosystem

Which of the above statements is/are correct?

Answer: [C] Both 1 & 2

Both are correct statements
Grazing food chain starts with green plants at first tropic level while the detritus food chain starts with dead organic matters at first tropic level. Energy for grazing food chain comes from sun while the detritus food chain receives energy from dead decay organic matter.
