Unit 2 Review

Front

What is the optimal temperature for Brook Trout survival?

Back

Brook Trout thrive best in water temperatures around 16 degrees Celsius.

Front

What is ecological succession?

Back

Ecological succession is the process by which ecosystems change and develop over time, often following a disturbance.

Front

What does higher biodiversity indicate about an ecosystem?

Back

Higher biodiversity indicates higher ecosystem resilience, meaning the ecosystem can better withstand changes and disturbances.

Front

Define genetic diversity.

Back

Genetic diversity refers to the variety of genes within a species, which contributes to the adaptability and survival of that species.

Front

What does the Theory of Island Biogeography suggest about species distribution?

Back

The Theory of Island Biogeography suggests that larger islands closer to the mainland have more species due to easier access and more resources.

Front

What is the significance of ecosystem resilience?

Back

Ecosystem resilience is significant because it determines how well an ecosystem can recover from disturbances and maintain its functions.

Front

What factors influence biodiversity in an ecosystem?

Back

Factors influencing biodiversity include habitat diversity, climate, availability of resources, and human activities.

Front

What is the difference between species diversity and genetic diversity?

Back

Species diversity refers to the variety of different species in a community, while genetic diversity refers to the variety of genes within a species.

Front

How does habitat fragmentation affect biodiversity?

Back

Habitat fragmentation can reduce biodiversity by isolating species populations, making it harder for them to reproduce and survive.

Front

What role do keystone species play in an ecosystem?

Back

Keystone species play a critical role in maintaining the structure of an ecosystem, influencing the types and numbers of other species.
