Population Ecology
100

Represents
relationships across
species/groups and Depicts the common
ancestors between groups

What is a Phylogenetic Tree

100

study of the interactions
between organisms and their
environment

What is Ecology

100

group of
individuals of the same
species that live in the
same place at the same
time.

what is Population

200

Population found at a branching points, which gives rise to all descendent species

What is a Common Ancestor 

200

how an individual
organism’s structure, physiology, and
behavior meet environmental challenges

What is Organismal Ecology

200

The number of individuals per unit area

What is density

300

Branching Points and Represents populations not individuals

What is a Node

300

how populations
change through time and what factors affect
population change & population size

What is population ecology

300

the pattern of spacing of individuals
within boundaries of the population

What is dispersion

400

Independently evolving lineages and Could contain many species along the way and Many branches are often excluded (e.g.
leading to extinct species

What is a Branch

400

how species interactions,
such as predation and competition, affect
community structure and organization

What is community ecology 

400

Study of
vital statistics and how
they change in a
population over time

What is demography

500

All branches and tips derived from a
given node

What is a clade

500

how energy flows and
chemical cycles between organisms and their
environment


What is ecosystem ecology

500

plots
the number of surviving
individuals at each age


What is a survivorship curve
