Total questions: 32
Worksheet time: 1hrs 5mins
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
Natural disturbances, such as fires or hurricanes, can result in
A.parasitism.
B.competition.
C.commensalism.
D.succession.
Which of the following is something that can create new land?
Snow
Rain
Volcanic Eruption
Wind
The first species to populate an area after a disturbance is called:
A pioneer species
A pilgrim species
A founder species
A primary species
What is a climax community? Select 2
The final community in an ecosystem
The first species to appear after a forest fire
Moss and lichen
Tall hardwood trees
During secondary succession, which of these best describes why decomposing pioneer plants give way to larger, more complex plant species, such as hardwood trees?
Increased amounts of sunlight are able to reach the ground while the pioneer species are decomposing
Increased soil temperatures from decomposing pioneer species help tree seeds germinate more quickly
Increased amounts of decomposing pioneer species remove nutrients that tree seedlings need to grow and mature
Increased amounts of soil from decomposing pioneer species allow plants with more extensive root systems to become established
The final stable community in an ecosystem at the end of succession is called the _____________.
pioneer species
climax community
primary population
carrying capacity
What is the main difference between primary and secondary ecological succession?
Primary begins without soil; Secondary begins with soil.
Both primary and secondary follow a natural disaster.
Primary builds plant community; secondary builds animal community.
Primary begins with soil; Secondary begins without soil.
Discuss the role of decomposers in the nutrient cycle of an ecosystem.
Decomposers produce energy for primary consumers.
Decomposers break down dead organic matter, returning nutrients to the soil.
Decomposers are primary producers in the ecosystem.
Decomposers compete with primary consumers for food.
Which of the following processes is most likely to occur after a volcanic eruption creates a new land surface?
Primary succession
Secondary succession
Climax community formation
Soil erosion
What role do lichens play in primary succession?
They provide shade for other plants.
They break down rocks to form soil.
They compete with pioneer species.
They increase soil fertility by fixing nitrogen.
Which for the following organisms would belong in the same Kingdom as a penguin?
In which domain does a mushroom belong?
