Pond Ecosystem Flashcard

Front

What is secondary succession in an ecosystem?

Back

Secondary succession is the process of ecological recovery that occurs in an area where a disturbance has destroyed an existing community but left the soil intact.

Front

What are pioneer species?

Back

Pioneer species are the first organisms to colonize previously disrupted or damaged ecosystems, often including weeds or mosses that can grow in direct sunlight.

Front

What factors can lead to secondary succession in a forest ecosystem?

Back

Factors such as fire, flooding, or human activities can lead to secondary succession by creating conditions that allow new species to establish.

Front

What is the role of gill breathing snails in a pond ecosystem?

Back

Gill breathing snails are aquatic organisms that extract oxygen from water, playing a role in the pond's food web and nutrient cycling.

Front

How do lung breathing snails adapt to their environment?

Back

Lung breathing snails have adapted to breathe air by climbing to the surface of the water, allowing them to survive in oxygen-poor environments.

Front

What is humus and its significance in a pond ecosystem?

Back

Humus is decomposed organic matter that enriches the soil, providing nutrients for plants and supporting the overall health of the pond ecosystem.

Front

What types of plants are commonly found in Pond A?

Back

Pond A typically has cattails, bulrushes, and water lilies, which are adapted to wetland environments.

Front

What is Chara and its role in a pond ecosystem?

Back

Chara is a type of green algae that provides habitat and food for aquatic organisms, contributing to the biodiversity of the pond.

Front

How does the presence of different plant types affect pond ecosystems?

Back

Different plant types provide various habitats, food sources, and contribute to the overall biodiversity and stability of the pond ecosystem.

Front

What is the importance of sunlight for pioneer plants?

Back

Sunlight is crucial for pioneer plants as they often require direct sunlight to photosynthesize and grow in disturbed areas.
