Biodiversity Skills Assessment

What is the term used to describe the variety of different species in an ecosystem?

• Varietality

• Ecosystemity

• Biodiversity

• Speciesverse

Explain why biodiversity is important for the overall health of an ecosystem.

• Biodiversity ensures resilience, stability, and productivity by providing various ecosystem services.

• Ecosystems thrive better with limited species diversity

• Biodiversity has no impact on ecosystem health

• Biodiversity leads to ecosystem imbalance

How does biodiversity contribute to the stability of an ecosystem?

• Biodiversity only benefits a few select species in an ecosystem

• Biodiversity provides resilience, adaptability, and maintenance of ecosystem functions.

• Biodiversity has no impact on the stability of an ecosystem

• Biodiversity leads to the extinction of species in an ecosystem

Compare the biodiversity in a rainforest ecosystem to a desert ecosystem.

• Desert ecosystems have higher biodiversity compared to rainforest ecosystems.

• Rainforest ecosystems have higher biodiversity compared to desert ecosystems.

• Biodiversity in rainforest ecosystems is not affected by the climate.

• Both rainforest and desert ecosystems have similar levels of biodiversity.

Identify three different species commonly found in a freshwater habitat.

• Cattail

• Goldfish, Mallard Duck, Water Lily

• Frog

• Trout

Discuss the role of keystone species in maintaining biodiversity.

• Keystone species have no impact on biodiversity

• Keystone species help regulate populations, promote diversity, and maintain community structure.

• Keystone species only focus on a single species in an ecosystem

• Keystone species decrease biodiversity

Why is genetic diversity important within a species for long-term survival?

• Genetic diversity allows for adaptation and resilience in the face of changing conditions.

• Genetic diversity increases the likelihood of extinction

• Genetic diversity hinders the ability to adapt to new environments

• Genetic diversity leads to inbreeding and genetic disorders

Analyze the impact of human activities on biodiversity loss.

• Biodiversity loss is caused by natural factors only

• Human activities have no impact on biodiversity loss

• Biodiversity loss is reversible and not a concern

• Human activities directly contribute to biodiversity loss through deforestation, pollution, overfishing, and habitat destruction.

Explain the concept of ecosystem services and how biodiversity plays a role in providing them.

• Ecosystem services are not affected by the health of ecosystems

• Ecosystem services are only related to human activities, not biodiversity

• Ecosystem services are benefits humans obtain from ecosystems, and biodiversity ensures the resilience and stability of ecosystems to provide these services.

• Biodiversity has no impact on ecosystem services

Compare and contrast the biodiversity in a coral reef ecosystem and a grassland ecosystem.

• Grassland ecosystems have higher biodiversity compared to coral reef ecosystems.

• Both coral reef and grassland ecosystems have similar levels of biodiversity.

• Coral reef ecosystems have lower biodiversity compared to grassland ecosystems.

• Coral reef ecosystems have higher biodiversity compared to grassland ecosystems.
