Ecological Succession and Biomes

Front

What is ecological succession?

Back

Ecological succession is the process by which ecosystems change and develop over time, involving a series of stages that lead to a stable community.

Front

What are pioneer species?

Back

Pioneer species are the first organisms to colonize previously disrupted or damaged ecosystems, playing a crucial role in soil formation and nutrient addition.

Front

What is primary succession?

Back

Primary succession occurs in an area where no soil exists, such as after a volcanic eruption or glacier retreat, leading to the gradual establishment of a biological community.

Front

What is secondary succession?

Back

Secondary succession occurs in areas where a disturbance has destroyed an existing community but left the soil intact, allowing for faster recovery compared to primary succession.

Front

What is a biome?

Back

A biome is a large geographic biotic unit, a major community of plants and animals with similar life forms and environmental conditions.

Front

What are the two main types of ecological succession?

Back

The two main types of ecological succession are primary succession and secondary succession.

Front

What role do mosses and lichens play in primary succession?

Back

Mosses and lichens are pioneer species that help create soil by breaking down rocks and adding organic material.

Front

What is the difference between primary and secondary succession in terms of soil presence?

Back

Primary succession occurs in areas with no soil, while secondary succession occurs in areas where soil is already present.

Front

What is a tropical grassland?

Back

A tropical grassland, also known as savanna, is a biome characterized by warm temperatures and seasonal rainfall, with distinct wet and dry seasons.

Front

What is the significance of biodiversity in an ecosystem?

Back

Biodiversity enhances ecosystem productivity, stability, and resilience, allowing ecosystems to better withstand environmental changes.
