- Q1Ecological succession can best be described as:Species that survive best when there is little or no competition in an area.The dominant species in one particular areaA change in weather.A gradual change in plant and animal life in an ecosystem over time.120s
- Q2What is one way secondary succession differs from primary succession?Secondary succession only occurs in mountains, primary succession only occurs in wetlands.Secondary succession is typically quicker than primary succession.Secondary succession is typically slower than primary succession.Secondary succession is the gradual change in plant species, while primary succession is the gradual change in animal species.120s
- Q3A community of moss and lichens growing on an outcrop of a rock is an example of:Primary successionA behavioral adaptationSecondary successionA climax community120s
- Q4Which of the following represents secondary succession?Plants growing on sand dunes.Moss growing on top of rocks.Plants growing in a forest that was destroyed by fire.Plants growing on a new volcanic island that formed in the ocean.120s
- Q5The graph shows how the number of species in a particular ecosystem changed over a 200-year period. The top number is 30,000. What is one conclusion you can make?The number of species decreased (went down) the most during the last 80 years.The number of species increased (went up by 25,000 over a period of 200 years.The number of species decreased (went down) by 25,000 over a period of 200 years.The number of species increased (went up) the most during the first 80 years.120s
- Q6Which statement about pioneer species is TRUE?Pioneer species, such as hardwood trees, thrive during the final stages of ecological succession.Pioneer species require soil to grow.Pioneer species thrive during the early stages of ecological succession.Pioneer species are organisms that are made up of only one cell.120s
- Q7As ecological succession progresses, a pioneer community gradually changes into a climax community. What typically happens?The number of species decreases/goes down.The organisms in the area can no longer find food.The organisms in an area decrease/reduce in size.The number of species increases/goes up.120s
- Q8The process of ecological succession usually begins after all of the following EXCEPT:FloodingForest FiresRain ShowersVolcanic Eruptions120s
- Q9An empty lot that was only covered in dirt ten years ago is now home to many different species of plants and animals. What can you infer?The animals will not survive because there are not enough plants.There are more nutrients in the soil compared to ten years ago.There are more rocks in the soil compared to ten years ago.People must have planted all the plants in the empty lot.120s
- Q10Which of the following is TRUE?Secondary succession begins with bare rock.Lichen rhymes with kitchen.A forest fire would cause primary succession to occur afterward.Lichen is a pioneer species made of an algae and a fungus120s
