the place an organism lives that includes all the factors necessary for its survival
habitat
wildflowers would show this type of distribution
random distribution
competition within the same species
intraspecific competition
Which group of living things has the highest species biodiversity?
insects
this is the development of a new species from an existing species
speciation
the abundance of a species in an area when compared to other species
species evenness
(births + immigration) - (deaths + emigration)
population change
this is the total amount of energy that producers make from the sun or from chemicals
GPP
When pieces of a habitat are removed, leaving behind only some sections of suitable habitat for species
habitat fragmentation
these fossils are extinct aquatic arthropods that died out during the Permian mass extinction
trilobites
the lowest or smallest level of ecology
organism
a method of random sampling that involves laying out a straight rope on the ground and counting the species touching the rope or a certain distance from the rope
quadrat method
this describes when two or more species live in close association and have a long-term relationship
symbiotic
What is overall the greatest threat to biodiversity?
habitat loss
Roughly how many species are on Earth including those we have not identified?
8.7 million
a group of individuals that actually or potentially breed in nature
species
factors that have an equal effect on a population regardless of the population density
density independent factors
this describes when two species live in the same area and use the same resource (habitat, food source, etc.) but use it in such a way that does not exclude the other species from using it
resource partitioning
This is a specific type of pollution where harmful substances reach water sources through erosion
runoff
What is the oldest fossil found on Earth
stromatolites
the role a species plays in its environment that includes where it lives, what it eats, how it gets its food, when it is active, etc.
niche
the maximum size a population can reach due to births if each member of the population survives and reproduces
biocapacity
these are microscopic organisms that are producers and include tiny plants, algae, and dinoflagellates
phytoplankton
List all three types of biodiversity
species
genetic
ecological
What is the name of the plant that humans selectively bred to create cauliflower, kale, cabbage, and broccoli?
wild mustard
