The study of the interactions between organisms and their environment is:
Ecology
Microbiology
Biology
Evolution
All living things in a given area, living and non-living.
Ecosystem
Biotic
Community
Species
All the organisms of the same species living in the same area
Community
Population
Habitat
Ecosystem
A group of very similar organisms that can mate and reproduce offspring of the same type
Community
Population
Species
Niche
An entity that displays all of the characteristics of life. Has the ability to maintain homeostasis
animal
organism
species
trophosphere
Which of the following is the highest level of organization within the environment?
population
organism
ecosystem
biosphere
An organism whose presence, absence or abundance reflects a specific environmental condition:
keystone species
exotic species
indicator species
native species
endangered species
Species that is NOT native to a specific location AND has a tendency to spread/damage the environment:
native species
invasive species
endemic species
exotic species
extinct species
Species that are crucial to the functioning of an ecosystem
keystone species
exotic species
invasive species
indicator species
endangered species
Species that is NOT native to a particular region.
exotic species
endangered species
native species
endemic species
indicator species
Elephant
K-selected
R-Selected
Bacteria
K-selected
R-selected
Two species of fish hunt the same prey in the same bay, one of them declines over time until it is no longer in the bay. This is an example of
overshoot
competitive exclusion
resource partitioning
community partitioning
When certain exotic species are introduced into a geographical area they become invasive mainly because
The invaded land has unlimited resources for the introduced species
The population of the introduced species in the invaded area is very low
The invaded land does not have its natural predator
Introduced species do not face any competition in the introduced land
the differentiation of niches that enables similar species to coexist in a community
character displacement
climax community
resource partitioning
pioneer species
