The document explains the food chain, highlighting the transfer of food energy from producers to various consumers (herbivores, omnivores, carnivores, and decomposers). It defines each component, including primary producers like plants, different levels of consumers, and decomposers that recycle energy from dead organisms. The document concludes with an offer for further questions.

2. Trip to zoo
A few days earlier, I had been to zoo with my cousins. My younger cousin who was there for
the first time was wondering what all those animals eat. So I explained him the food chain
properly and all the components of it.
I started from what the food chain is - I continued simply and precisely.
“The transfer of food energy from the producers, through a series of organisms
(herbivores to carnivores to decomposers) with repeated eating and being eaten, is
known as Food Chain.
Then he raised the question, What are herbivores , Carnivores and all that ?

Components of Food Chain
● Producers - Base of the Food Chain.
● Herbivores - Feed on Producers.
● Omnivores - Feed on both plants and animals.
● Carnivores - Feed on herbivores, omnivores, & other carnivores
○ 1st level Carnivores - Feed on Herbivores.
○ 2nd level Carnivores - Feed on 1st level carnivores.
● Decomposers - They are final consumer group. They use the energy in dead plant
and animals. They transform organic material into inorganic.
