Biodiversity & Classification
What is the broadest level of classification in the taxonomic hierarchy?
Domain
What type of relationship occurs when both species benefit from the interaction?
Mutualism
What term describes the maximum number of individuals that an environment can support sustainably?
Carrying Capacity
What human activity is the leading cause of habitat destruction?
Deforestation (Australia is especially bad for this)
What NRL team do I support?
Gold Coast Titans (I will be forever sad)
What term describes the variety of species, genetic diversity, and ecosystem diversity in a region?
Biodiversity
What term describes an organism’s functional role within an ecosystem?
Niche
Which type of population growth results in a J-shaped curve?
Exponential growth
Name one consequence of introducing an invasive species into an ecosystem.
Disruption of food webs, competition with native species, biodiversity loss, etc.
What was my previous career?
Geologist
What classification system is used to group organisms based on evolutionary ancestry?
Phylogenetic classification
What is the difference between fundamental and realized niche?
A fundamental niche is the full range of conditions a species could occupy, while the realized niche is where it actually exists due to competition and other factors.
In a S growth curve, what factor causes population growth to slow as it nears carrying capacity
Limiting factors such as food, space, and predation
What is eutrophication, and what causes it?
Nutrient runoff (e.g., from fertilizers) causes excessive algal growth, leading to oxygen depletion and ecosystem damage.

What is the correct order of the taxonomic hierarchy from Kingdom down to Species?
Kingdom, Phylum, Class, Order, Family, Genus, Species
Name one keystone species and explain why it is important.
Always Cassowary
What is the term for species that have high reproductive rates but low survival rates for offspring?
R selected Species
How does climate change impact coral reefs?
Coral bleaching due to increased sea temperatures and ocean acidification.
I have a pet parrot, can you remember his name?
Tingle
What type of biodiversity index takes into account both species richness and species evenness?
Simpson's Diversity Index
In the nitrogen cycle, which type of bacteria converts nitrogen gas into a form that plants can use?
Nitrogen-fixing bacteria
Name a K selected species?
Elephants
What ecological principle states that no two species can occupy the same niche indefinitely?
Competitive Exclusion Principle
