Ecosystem Succession and Biodiversity

The video tutorial covers the concepts of populations, ecosystems, and succession. It explains abiotic and biotic factors, the stages of succession from pioneering species to climax community, and the process of succession in both terrestrial and aquatic environments. The tutorial also discusses secondary succession and provides a summary with a flow diagram to consolidate learning.

What is the term for non-living factors in an ecosystem?

• Biotic factors

• Abiotic factors

• Biosphere

• Micro habitats

What is the maximum population size that an ecosystem can support called?

• Carrying capacity

• Biosphere

• Micro habitat

• Pioneering species

What is the first species to colonize a barren environment known as?

• Abiotic factor

• Pioneering species

• Climax community

• Biotic factor

Which stage of succession is characterized by a stable community with little change?

• Abiotic stage

• Intermediate stage

• Climax community

• Pioneering stage

In succession, what role do organic plants play in the animal kingdom?

• They provide shelter and food

• They increase abiotic factors

• They decrease biodiversity

• They prevent succession

What is the process of succession in an aquatic environment leading to a forest called?

• Pond succession

• Aquatic succession

• Forest succession

• Climax succession

What is a key factor in the formation of soil during succession?

• Absence of plants

• Increased water

• Decomposed organic matter

• Lack of nutrients

What is secondary succession?

• Development of aquatic environments

• Recovery of an ecosystem after disturbance

• Formation of climax communities

• Initial colonization of barren land

How does secondary succession differ from primary succession?

• It does not lead to climax communities

• It starts with bare rock

• It is slower

• It occurs faster due to existing soil

What happens to biodiversity during the stabilization of a community?

• It remains constant

• It fluctuates

• It increases

• It decreases
