unit 1 and 2 review
Where rooted plants cannot survive in open water in lakes and ponds as deep as the sunlight can penetrate.
What is limnetic zone?
k selected species are typically on this survivorship curve
what is type 1?
an example of a density dependant factor
what is water, food, shelter?
replacement fertility is a TFR of
what is 2.1?
what is stage 4?
The best explanation of why large islands contain more species is that
what is larger islands have more available niches in a larger habitat, which can support more species?
the species type more likely to be an invasive species or bounce back from a disruption
what is r selected species?
an example of a density idependant factor
what is a natural disaster, freezing weather, hurricane, or volcano?
if every woman in China only had one child what is her TFR?
what is 1?
stage 2 of demographic transiton has replacement fertility ____ and crude death rate _____
what is replacement fertility decrease slightly and death rate to decrease rapidly.
The trophic level of eagles that consume fish that consume zooplankton that eat algae.
What is tertiary?
this species type is generally good at parenting
what is k selected speices？
the s shaped curve top most region is near this
what is the carrying capacity?
the difference between a rate (CBR) and a percent
what is rate is out of 1000, and percent is out of 100?
generally the higher the GDP and the higher education the average person has will do this to the TFR
what is the TFR will decrease?
This best describes an environmental problem associated with a sudden decrease in the population of a keystone species in an ecosystem.
What is the loss of a keystone species can have a cascading effect on the populations of other species in its food web.
example of a k selected speices also in the type one survirorship curve
what is a whale, elephant, or human?
an animal with high fecundity
what is a rabbit, pig or bulfrogs?
doubling time is calculated this way
what is the rule of 70: 70/% growth
the two stages where the population grows in the demographic transition
what is stage 2 and 3?
Researchers estimate that the loss of bats would raise agriculture costs by about $75 per acre, in terms of the pesticides needed to replace them. In 2014, this was estimated to cost the state of Pennsylvania $300 million. Calculate the number of acres of farmland affected by the loss of bats.
What is 4,000,000 acres?
describe a type two survivorship curve
what is a straight line, negative correlation, practically at a 45 degree angle?
how to increase the carrying capacity of the earth for humans?
what is technology advances, lowering meat consumption, and less waste of resources?
a city has a CBR of 17 and a CDR of 15, when will the population double?
what is 2/10 then put that % into the rule of 70 to get 70/0.2=350 years
0.5=(12-0.14)-(CDR+0.5）/10
5=11.86-CDR-0.5
CDR=6.36 per 1000 individuals
