The functional role of an organism in its habitat.
What is niche?
100
The are bottom-dwelling organisms that are big enough to see with the naked eye and have no spine.
What are benthic macroinvertebrates?
100
The life cycle of an insect that has 4 stages.
What is complete metamorphosis? (Can you name the 4 stages? Which are aquatic?)
100
King Phillip Came Over For Great Spaghetti
What is a mnemonic to remember the order of Linnaeus's classification levels? (Which level is most specific?)
200
An organism that has a broad niche and can adapt to a wide range of habitats.
What is a generalist?
200
An organism that has a narrow niche and can only live in a specific habitat.
What is a specialist?
200
Organisms whose presence tells us something about their environment.
What is an indicator species?
200
The couplets of questions that lead you through a multistage classification and can help you identify an organism.
What is a dichotomous key?
200
The number of different kinds of an organism.
What is richness?
300
It gives a visual representatioin in graph form of breadth of niche.
What is a tolerance curve?
300
The genetic change in populations over generations that is a result of natural selection.
What is biological evolution?
300
A tool to measure biodiversity that incorporates data on pollution tolerance of organisms and their richness to calculate a water quality score.
What is a pollution tolerance index?
300
Conditions that favor biodiversity.
What are the conditions that favor specialists? (Generally clean, stable habitats.)
300
The number of individuals of each type of organism.
What is evenness?
400
The quality of an organism that allows it to actively choose a habitat from a variety of options (within limits).
What is mobile?
400
The quality that forces as an organism not be able to actively choose their habitat. Its more that the habitat choose them - that the organism will simply survive or perish in it.
What is sessile?
400
A fraction that quantifies evenness. (The population of the most abundant order divided by the total number of organisms identified)
What is dominance index?
400
The reasons that benthic macroinvertebrates are good indicators of water quality.
What are varying niches when it comes to pollution tolerance and limited powers of habitat selection (being sessile)?
400
Traits that enhance survival and reproduction are passed on to the next generation more often than those that do not.
What is natural selection?
500
Regions of DNA coding for a particular trait.
What are genes?
500
He proposed the outdated hypothesis that speciation occurs because animals want and need to develop certain adaptations.
Who is LaMark?
500
The life cycle of an insect that has 3 stages.
What is incomplete metamorphosis? (Can you name the 3 stages? Which are aquatic?
500
Two aspects of biodiversity that must always be considered when measuring it.
