Q: Define ecological pyramids. Describe the pyramid of number, pyramid of biomass, and pyramid of energy with suitable examples and mention the limitations of ecological pyramids.

Definition of Ecological Pyramids\nThe representation of a chain of organisms in terms of energy, biomass, or number, starting from producers at the base to top carnivores at the apex, is known as an ecological pyramid. The base of a pyramid represents producers or the first trophic level, while the

Q: Explain the concept of ecological succession in detail. Discuss the different types of succession, the process of succession, and the concept of climax community with special reference to hydrarch and

Introduction to Ecological Succession\nEcological succession is the process by which the structure of a biological community evolves over time. Two main types are primary succession (starting on lifeless areas like newly cooled lava or bare rock) and secondary succession (starting in areas where nat

Question 3

Who amongst the following scientists coined the term 'Ecosystem' in 1935?

Accepted Answer

The term 'Ecosystem' was first proposed by the British botanist A.G. Tansley in 1935. An ecosystem is defined as a structural and functional unit of biosystem consisting of living organisms and their non-living environment interacting with each other.

Question 4

The rate of formation of new organic matter by consumers in an ecosystem is referred to as:

Accepted Answer

Secondary productivity is defined as the rate of formation of new organic matter by consumers. Primary productivity is the rate at which organic matter is produced by producers (plants) during photosynthesis.

Question 5

Which of the following correct mathematical equations represents Net Primary Productivity (NPP)?

Accepted Answer

Net Primary Productivity (NPP) is the total organic matter stored by green plants after subtracting the energy lost through respiration (R). Thus, NPP = GPP - R, where GPP is Gross Primary Productivity.
