solution
What is the measurement of a population per unit area?
population density
Overcrowding is an example of
density dependent factor
What is a survivorship curve?
It shows the number of individuals living at each age interval plotted versus time. It
helps to compare life histories of different populations. You can compare the life
histories of birds, frogs, and humans at the same time. It is also known as a mortality
table.
random population distribution
haphazardly located individuals, with no pattern
clustered population distribution
Clustered population is where many people are living in the small area. ..
scattered population distribution
A scattered population is a population distribution when a small amount of people are
living in a big area. Scattered populations have limited resources and only a little
amount of people are supported.
Claire, an ecologist, is finding it difficult to identify an interaction in nature because of
changing environmental conditions and the complex indirect interactions of multiple
species. Which interaction is Claire trying to find in nature?
A. interference competition
B. apparent competition
C. exploitation competition
D. predation
E. symbiosis
B. apparent competition
Commensalism
A relationship between two organisms in which one organism benefits and the other is
unaffected
predation
An interaction in which one organism kills another for food.
exploitation competition
organisms compete indirectly through the consumption of a limited resource
mutualism
A relationship between two species in which both species benefit
parasitism
A relationship between two organisms of different species where one benefits and the
other is harmed
What are the regions in the environment that provide basic needs, such as food, shelter,
mates for reproduction, and protection, for survival of living organisms?
Habitats are regions in the environment that provide basic needs, such as food, shelter,
mates for reproduction, and protection, for survival of living organisms.
