Several different populations in the same geographic area
A population is
a group of similar species in different areas

a group of several species in the same geographic area
a group of several species along with their abiotic factors in a small area.
A very destructive typhoon would start:
common succession
primary succession
secondary succession
quaternary succession
Species that are critical to the functioning of an ecosystem are known as
biodiversity
keystone species
main species
native species
Biodiversity, aka biological diversity, usually refers to
the same species in a general location
the number of different species in a given area
the number of animal species in a given area
the number of plant species in a given area
High biodiversity is a sign of a healthy ecosystem.
True

Food Chain
Food Web

Endangered diversity
Species diversity
Genetic diversity
High Risk diversity
Ecosystem diversity
When would we see a climax community?
A few days after a fire.
After an ecosystem fully develops.
Before pioneer species can be established.
Only in primary succession
Secondary succession begins
on bare, exposed rock.
after a disturbance like a forest fire.
Species richness is
a measure of how all of the individual organisms in an ecosystem are balanced between the different species.
