Question

Identify the correctly matched pairs among the following:

(a) Consumers - autotroph members of the ecosystem

(b) Producers - act upon decomposed substances and transfer them into different forms of inorganic and organic substances

(c) Decomposers - feed on dead and decaying matter and break them into simpler compounds fit for use by producers

(d) Solar light - source of energy for all without any exception, reaching every part of the Earth

Choose the correct option:

• A. a and c
• B. b and d
• C. c only
• D. c and d

Answer 1

The correct option is C c only

Producers-

• All the autotrophs of an ecosystem belongs to producers
• They have the ability to convert physical energy into chemical energy and this energy is available for remaining living organisms

Consumers-

• Most of the heterotrophs of an ecosystem are consumers
• They are divided into primary, secondary and tertiary consumers on the basis of their food habits (who eats whom)

Decomposers-

• Heterotrophic organisms like bacteria, fungi, Slime molds and Earthworm etc., belong to decomposers
• Feed on dead and decaying living matters and break them into simpler compounds fit for use of producers

Solar radiation is the ultimate source of energy for all, with the exception of the deep ocean ecosystem where sunlight never reaches. Thus from the above statements only stament ‘c’ is correctly matched.
