HW - Biomes and Succession 1

Front

What is primary succession?

Back

Primary succession is the process of ecological change that occurs in an area where no soil exists, starting with bare rock and leading to the establishment of a biological community, often beginning with pioneer species like lichen.

Front

What is secondary succession?

Back

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

Front

What defines a biome?

Back

A biome is a large geographical area characterized by its climate, soil, plants, and animals. Examples include deserts, forests, grasslands, and tundras.

Front

What is a climax community?

Back

A climax community is a stable and mature ecological community that has reached a steady state, experiencing minimal changes over time.

Front

What are pioneer species?

Back

Pioneer species are the first organisms to colonize previously disrupted or damaged ecosystems, often initiating the process of ecological succession.

Front

What is the temperate grassland biome known for?

Back

The temperate grassland biome is characterized by cold winters, warm summers, moderate seasonal precipitation, fertile soils, and occasional wildfires.

Front

What type of forest is known for trees with broad leaves that fall off in winter?

Back

Deciduous forests are known for trees that shed their leaves in the fall, adapting to seasonal changes.

Front

What is the difference between a biome and an ecosystem?

Back

A biome is a larger classification of ecosystems that share similar climate and biological communities, while an ecosystem is a specific community of living organisms interacting with their physical environment.

Front

What role do wildfires play in temperate grasslands?

Back

Wildfires in temperate grasslands help to maintain the ecosystem by clearing out old vegetation, promoting new growth, and maintaining species diversity.

Front

What is aquatic succession?

Back

Aquatic succession is the process of change in aquatic ecosystems, where a body of water gradually changes into a terrestrial ecosystem over time.
