Ecological Succession & Biodiversity

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 urban areas.

• Primary succession is the process of ecological succession that occurs in aquatic environments.

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

Define secondary succession.

• The initial establishment of a community in a new area

• The introduction of invasive species to an ecosystem

• The process of soil erosion in an ecosystem

• The reestablishment of a community following a disturbance in an area where the soil is still intact.

Explain the concept of climax community.

• A climax community is always in a state of constant change.

• A climax community is a temporary stage in ecological succession.

• A climax community is formed by the introduction of invasive species.

• A climax community is a stable, self-sustaining ecological community that has reached a state of equilibrium.

What are pioneer species?

• Organisms that only live in water ecosystems

• Plants that require a lot of sunlight to survive

• Species that are at the top of the food chain

• First organisms to colonize a newly exposed area or ecosystem.

Why are biodiversity hotspots important?

• Biodiversity hotspots are important for increasing pollution levels

• Biodiversity hotspots are important for promoting monoculture farming

• Biodiversity hotspots are important for reducing species extinction

• Biodiversity hotspots are important for preserving unique species and maintaining ecosystem stability.

Describe the term sustainable in the context of ecosystems.

• The ability of an ecosystem to deplete its resources rapidly

• The concept of ecosystems being self-sufficient without human intervention

• The ability of an ecosystem to maintain its essential functions and biodiversity over time.

• The idea that ecosystems can thrive without biodiversity

How would you define an ecosystem?

• An ecosystem is a group of people working together

• An ecosystem is a community of living organisms in conjunction with the nonliving components of their environment, interacting as a system.

• An ecosystem is a type of computer software

• An ecosystem is a type of musical instrument

What role do pioneer species play in ecological succession?

• Pioneer species only thrive in the final stage of ecological succession

• Pioneer species have no impact on ecological succession

• Pioneer species play a crucial role in initiating ecological succession by preparing the environment for more complex species.

• Pioneer species prevent ecological succession from occurring

Why is it important to protect biodiversity hotspots?

• To increase pollution levels, disrupt ecosystems, and harm human health.

• To reduce species diversity, destabilize ecosystems, and decrease food security.

• To preserve unique species, maintain ecosystem stability, and benefit human health and food security.

• To promote extinction of unique species, create ecosystem imbalances, and negatively impact human health.

How can human activities impact the sustainability of an ecosystem?

• Human activities always improve ecosystem sustainability

• Human activities can impact the sustainability of an ecosystem by disrupting the balance, reducing biodiversity, altering habitats, and depleting resources.

• Human activities have no impact on ecosystem sustainability

• Ecosystems are not affected by human activities
