10 Questions
What is the defining characteristic of a stable ecosystem?
Constant species evenness, density, and population size
Why can stable populations come close to ideal ecological stability?
Due to high levels of genetic diversity within populations
What is a key advantage of a rainforest ecosystem when a species goes extinct?
High diversity of similar species to fill ecological roles
Why is ecological diversity rich on a smaller scale in rainforests?
High variation in canopy cover, moisture, and temperatures in small areas
What is a major threat to rainforests leading to their global decline?
Habitat destruction and overuse of resources
How do rainforests maintain high levels of genetic diversity?
Through populations with enough numbers
What role does species evenness play in a stable ecosystem?
Maintaining a balance in different species populations
Why are rainforests considered relatively stable ecosystems?
High species diversity allowing for role filling by similar species
What causes rainforests to face extinction despite being highly diverse?
Increased habitat destruction and overuse of resources
What best describes the impact of overharvesting on an ecosystem?
Increased vulnerability as other species struggle to fill depleted roles
Explore the concepts of alpha, beta, and gamma diversity and how they are measured between different ecosystems. Learn about genetic biodiversity and the diversity of genomes within an ecosystem, including nucleotide diversity at varying scales.
