What is one way secondary succession differs from primary succession?
Secondary succession is typically quicker than primary succession
Secondary succession is typically slower than primary succession
Secondary succession only occurs in mountains, primary succession only occurs in wetlands
Secondary succession is the gradual change in plant species, while primary succession is the gradual change in animal species

The graph below shows how the number of species in a particular ecosystem changed over a 200 year period. What is one conclusion you can make based on the information in the graph?
The number of species increased the most during the first 50 years
The number of species decreased by 25,0000 over a period of 200 years
The number of species decresed the most durin gthe last 80 years
The number of species increased by 25,000 over a period of 200 years.
Which statement about pioneer species is TRUE?
Pioneer species require soil to grow
Pioneer species are organisms made up of only one cell
Pioneer species thrive during the early stages of ecological succession
Pioneer species, such as hardwood trees, thrive during the final stages of ecological succession
As ecological succession progresses, a pioneer community gradually changes into a climax community. What typically happens during this process?
The number of species increases
The number of species decreases
The organisms in an area decrease in size
The organisms in an area can no longer find food
The process of ecological succession usually begins after all of the following EXCEPT:
Flooding
Forest Fire
Rain Showers
Volcanic eruptions
An empty lot that was only covered in dirt ten years ago is now home to many different species of plants and animals. Based on your knowledge about ecological succession, what can you infer?
People must have planted all the plants in the empty lot
There are more rocks in the soil compared to 10 years ago
There are more nutrients in the soil compared to ten years ago
The animals will not survive because there is not enough plants.
