Unit 3 Lesson 3

Front

What is primary succession?

Back

Primary succession is the process of ecological change that occurs in an area where no soil exists, such as after a volcanic eruption.

Front

What role do pioneer species play in primary succession?

Back

Pioneer species break down bare rock into soil, allowing plants to grow and further develop the ecosystem.

Front

What is secondary succession?

Back

Secondary succession is the process of ecological change that occurs in an area where soil exists but has been disturbed, such as after a forest fire.

Front

What is natural eutrophication?

Back

Natural eutrophication is the process by which a body of water becomes enriched with nutrients, leading to increased plant growth and decay.

Front

How can a pond become a meadow?

Back

A pond can become a meadow through the process of natural eutrophication, where nutrient enrichment leads to plant growth that fills the pond.

Front

Why are plants considered primary producers?

Back

Plants are primary producers because they convert sunlight into energy through photosynthesis, forming the base of the food web.

Front

What happens to biodiversity when plant populations decline?

Back

A reduction in biodiversity due to loss of plant populations can destabilize ecosystems, as plants are crucial for food and habitat.

Front

How do ecosystems change over time?

Back

Ecosystems constantly change due to natural processes, human activities, and interactions among organisms.

Front

What is the significance of biodiversity in an ecosystem?

Back

Biodiversity is important because it enhances ecosystem resilience, productivity, and stability.

Front

What is an example of a pioneer species?

Back

Lichens and mosses are examples of pioneer species that can colonize bare rock.
