Question

Which of the following is a logical sequence of food chain
(a) producer → consumer → decomposer
(b) producer → decomposer → consumer
(c) consumer → producer → decomposer
(d) decomposerproducer → consumer

Answer 1

producer --> consumer --> decomposer

Explanation:

producers : use energy and inorganic molecules to make food.

consumers : take in food by eating producers or other living things.

decomposers : break down dead organisms and other organic wastes.

Answer 2

The following is a logical sequence of food chain:

(a) producer → consumer → decomposer

What is a food chain?

• The food chain represents the flow of energy from one organism to another in a logical sequence.
• There are different levels in a food chain known as trophic levels.

The three trophic levels of the food chain are explained below:

Producer:

• Green plants are placed under producers as they absorb energy from sunlight by using carbon dioxide during the process of photosynthesis.
• Food chains mostly start with producers.

Consumer:

• The organisms that obtain energy from the producers are called consumers.
• These organisms cannot absorb energy directly from sunlight and hence depend on producers.

Decomposer:

• The organisms that decompose the dead and decaying organic matter back into inorganic nutrients are called decomposers.
• Decomposers form an important part in any food chain.
