Sucesion Ecologica

The video tutorial explains ecological succession, a process of change in ecosystems. It covers primary succession, which occurs in new habitats like post-volcanic areas, and secondary succession, which happens in pre-existing habitats after disturbances. The process concludes with ecological climax, where stability is achieved between the community and ecosystem.

What is the primary role of ecological succession in an ecosystem?

• To introduce new species into the ecosystem

• To eliminate invasive species from the ecosystem

• To maintain the current state of the ecosystem

• To gradually change the composition or structure of the ecosystem

Which type of succession occurs in a habitat that lacks soil?

• Secondary succession

• Climax succession

• Primary succession

• Tertiary succession

What typically initiates primary succession?

• A volcanic eruption

• Human deforestation

• A forest fire

• A flood

Why is secondary succession generally faster than primary succession?

• Because it occurs in a completely barren area

• Because it requires less sunlight

• Because soil and seed banks are already present

• Because it involves the introduction of new species

What is the term for the stable state reached at the end of ecological succession?

• Ecological plateau

• Ecological peak

• Ecological climax

• Ecological balance
