Question

In an ecosystem, there is flow of energy at different trophic levels. This is as follows : [KCET 1994]
A) Primary consumers - Tertiary consumers - Secondary consumers - Decomposers - Producers
B) Producers - Primary consumers - Secondary consumers - Tertiary consumers - Decomposers
C) Producers - Decomposers - Primary consumers - Tertiary consumers - Secondary consumers
D) Producers - Primary consumers - Tertiary consumers - Secondary consumers - Decomposers

Answer 1

b is correct sequence of question

Answer 2

Answer:

On the basis of energy flow in the ecosystem "Option B" is correct.

Producer → Primary Consumers → Secondary Consumers → Tertiary Consumers

Explanation:

Energy is required for the survival of the biotic components of the environment and this energy flow in various trophic levels in the ecosystem for the survival of the different living organism of these trophic levels

These trophic levels are classified into the following:

• First Trophic Level ( Producers)
• Second Trophic Level ( Primary Consumers)
• Third Trophic Level ( Second Trophic Level)
• Fourth Trophic Level ( Last Trophic Level)
• Decomposers

First Trophic Level ( Producers): Producers are the green plants and trees which make their own food with the help of abiotic components of the environment like air, water, sunlight, etc that's why they are called producers. Sun is the basic source of energy for them.

Second Trophic Level ( Primary Consumers): Primary consumers are those who get their energy by consuming Producers i.e Plants, Trees, etc. the examples of the animals in categories are cows, buffaloes, goats, etc.

Third Trophic Level ( Second Consumers): They are animals that get energy by consuming primary consumers or well as producers are known as secondary consumers for e.g Humans, Dog, Birds, etc

Fourth Trophic Level ( Last Trophic Level): This trophic level consists of organisms that are at top of the list in energy flow in an ecosystem. For e.g lions, peacocks. etc

Decomposers: Decomposers are the organism the get energy from dead organic matter for e.g bacteria, fungi, etc
