Community Ecology Quiz

Community Ecology

• The primary focus of community ecology is the interactions between different species in a community.

Biodiversity

• The main factor affecting the uneven distribution of biodiversity is the variation in environmental conditions such as temperature, rainfall, and latitude.

Ecosystems

• Coral reefs are considered the most productive and complex ecosystems on Earth.

Extinction

• Habitat destruction is the primary cause of extinction.

Interactions

• Mutualism is a type of interaction where both species benefit.

Symbiotic Relationships

• Mycorrhizal fungi live with plant roots and form a mutualistic relationship.

Autotrophic Organisms

• Autotrophic organisms are also known as producers.

Energy Transfer

• Only 10% of energy passes to the next trophic level.

Ecological Succession

• The term for the colonization of habitats devoid of life is primary succession.

Community Structure

• The term for the most abundant species in a community is dominant species.
• Keystone species have a large impact on the community structure by determining the food web of an ecosystem.

Biodiversity Hotspots

• Biodiversity hotspots are areas with high levels of endemism and species richness.

Genetic Variability

• Low genetic variability leads to reduced fitness and increased extinction risk.
• A small population can become stuck in an evolutionary dead end due to low genetic variability.
