Unit 2 Review Biodiversity

Front

What is secondary succession?

Back

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

Front

What is the relationship between island size and biodiversity?

Back

Small islands have fewer resources and as a result may have fewer species compared to larger islands.

Front

What occurs in the zone of physiological stress?

Back

In the zone of physiological stress, organisms can survive and grow, but they cannot reproduce.

Front

What does high species evenness indicate in a community?

Back

High species evenness indicates that species in a community are distributed more equally, meaning no single species dominates.

Front

Define species diversity.

Back

Species diversity refers to the variety of different kinds of organisms that make up a community.

Front

What is primary succession?

Back

Primary succession is the development of a biological community in an area that was previously uninhabited and devoid of soil.

Front

What is the significance of genetic diversity?

Back

Genetic diversity is important for the adaptability and survival of species, allowing populations to withstand environmental changes.

Front

Explain ecosystem diversity.

Back

Ecosystem diversity refers to the variety of ecosystems within a given area, including different habitats and ecological processes.

Front

What is the impact of invasive species on biodiversity?

Back

Invasive species can disrupt local ecosystems, outcompete native species, and lead to a decline in biodiversity.

Front

What is the concept of ecological niche?

Back

An ecological niche is the role and position a species has in its environment, including all interactions with biotic and abiotic factors.
