Succession

What is primary succession?

• Primary succession is the process of ecological succession that occurs in an area where no soil is present.

• Primary succession is the process of ecological succession that occurs in a desert ecosystem.

• Primary succession is the process of ecological succession that occurs in an area with abundant soil.

• Primary succession is the process of ecological succession that occurs in a marine environment.

Define secondary succession.

• The process of ecological succession that occurs in an area where the soil has been completely eroded

• The process of ecological succession that occurs in an area with no existing community

• The process of ecological succession that occurs in an area with intact soil but no vegetation

• The process of ecological succession that occurs in an area where an existing community has been partially or completely destroyed, but the soil is still intact.

Explain the concept of climax community.

• A climax community is a community that is always in a state of chaos and imbalance.

• A climax community is a community that is dominated by a single species and lacks biodiversity.

• A climax community is a temporary community that constantly changes with the environment.

• A climax community is a stable, self-sustaining community of plants and animals that has reached a state of equilibrium with the environment.

What are pioneer species?

• First organisms to colonize a newly exposed area

• Species that are at the top of the food chain

• Organisms that only live in water

• Plants that require a lot of sunlight

How does disturbance affect ecological succession?

• Disturbance speeds up ecological succession

• Disturbance has no impact on ecological succession

• Disturbance only affects the initial stages of ecological succession

• Disturbance affects ecological succession by altering the environment and species composition, potentially leading to a different successional pathway.

Differentiate between primary and secondary succession.

• Primary succession is faster than secondary succession.

• Secondary succession always starts with the same species as primary succession.

• Primary succession occurs in areas with soil, while secondary succession occurs in areas without soil.

• Primary succession occurs in areas without soil, while secondary succession occurs in areas with soil.

Give an example of a pioneer species.

• Pine tree

• Lichen

• Moss

• Fern

Why is the concept of climax community important in ecology?

• The concept of climax community is important in ecology because it hinders biodiversity.

• The concept of climax community is important in ecology because it represents a temporary and unstable ecosystem.

• The concept of climax community is important in ecology because it leads to rapid changes in the ecosystem.

• The concept of climax community is important in ecology because it represents a stable and self-sustaining ecosystem that has reached a state of equilibrium.

Discuss the role of pioneer species in ecosystem development.

• Pioneer species only thrive in established ecosystems.

• Pioneer species help in initiating the process of ecological succession by preparing the environment for more complex species to establish.

• Pioneer species have no impact on ecosystem development.

• Pioneer species hinder the growth of other species in the ecosystem.

How can human activities impact ecological succession?

• Human activities always promote ecological succession

• Human activities can disrupt the natural progression of ecological succession by changing the conditions and species composition of an ecosystem.

• Human activities speed up ecological succession in a positive way

• Human activities have no impact on ecological succession
