Match the following levels of classification to the pictures:
Organism
Population
Community
Ecosystem
Carrying capacity is the (a) number of organisms that can survive in an area based on the available (b) , such as food and water.
Identify this populations carrying capacity
What type of growth model is shown in image B?
Exponential
Logistic
In an ecosystem, there are populations of moose, rabbits, grass, and pine trees. Suddenly, a fire blazes through the area, which kills all of the populations. As the months go on, new species of grass begin to take root. This attracts animals, and eventually the ecosystem is restored.
What type of ecological succession happened?
Primary succession
Secondary succession
Tertiary succession
None of the above
Which is an example of where primary succession could occur?
a glacier melts and exposes new rocks
natural fire burns a prairie
a corn field is abandoned and left to overgrow
flood covers a piece of land
What percentage of energy is passed on to the next trophic level?
5%
10%
50%
90%
newly exposed or newly formed rock is colonized by living things for the first time. Certain hardy plants and lichens with few soil requirements, called pioneer species, colonize the area first.
Climax community
Primary succession
Ecological succession
Secondary succession
The first species to populate an area during succession.
Keystone species
Pioneer species
Foundation species
Invasive species
Primary or secondary ecological succession?
