Total questions: 15
Worksheet time: 1hrs 15mins
A wildfire in an oak and hickory forest burns most of the vegetation and kills animals unable to flee the area. Their nutrients, however, are returned to the ground in the form of ash. Since this disturbed area already has nutrient-rich soil, it can be recolonized much more quickly. What is this an example of?
Regime Shift
Secondary Succession
Trophic Cascade
Primary Succession
This is an illustration of forest succession after a disturbance. What are the first organisms that inhabit a barren landscape called?
Surtsey
Climax Species
Producers
Pioneer Organisms
The 2011 North Pacific Coast of Japan Tsunami, 2018 Paradise Camp Fire, 1986 Chernobyl Nuclear Disaster are all examples of
Symbiosis
Climax Community
Severe Disturbances
Ecological Restoration
What was Mr. Andersen from the Task 1 Video we watched in class trying to illustrate with these images (Year 1-5)?
Deforestation
Climax Species
Ecological Succession
Eradication
What abiotic factors make it possible for soil to gather and build on rock landscapes? Select all that apply
Erosion
Wind
Birds
Rain
What is the primary difference between primary and secondary succession?
Primary= no soil remains
Secondary= soil remain
Primary= soil remains
Secondary= no soil remains
None of the above
A mutualistically symbiotic relationship between an algae and a fungus represents what type of organism?
Lichen
Fern
Moss
Pollinator
Mosses are beneficial organisms that participate in the initial steps of life coming back to an area that has been been impacted by a severe disturbance. What are some important characteristics of these organisms? Select all that apply
Mosses live in moist environments
Mosses do not have roots
Mosses have structures called rhizoids
Mosses are photosynthetic
Both bushes and trees require _____ _____ in order to thrive.
Deep soil
Much shade
Primary consumers
Secondary consumers
Based on the video we watched in class, this graph shows how after a severe disturbance, the land has bare rock. The amount of bare rock is going to drop off as vegetation starts to come in. Once you reach the end of the graph, the climax community consists of full-grown tall trees. How do these trees affect smaller plants?
Help control the population of primary consumers
Produce waste products that poison the smaller plants
Produce shade that will make it more difficult for smaller species to compete for life
Have long roots that dig into the soil and cut off supply of water and nutrients to smaller plants
Primary consumers eat producers such as plants and make the soil around them more fertile by making waste products. What is an example of a primary consumer?
Hawk
Fungus
Deer
Crayfish
Secondary consumers prey on primary consumers such as grasshoppers. What are some examples of secondary consumers? Select all that apply
Fish
Chipmunks (rodents)
Birds
Wolves
Predators that feed on still higher trophic levels are known as tertiary consumers. In other words, they prey on primary and secondary consumers. What is an example of a tertiary consumer?
Phytoplankton
Milipedes
Hawk
Algae, fungi, bacteria, lichens colonize on the bare rocks and provide organic materials for further higher level of colonization. These are examples of _______.
Mutualistic Symbiosis
Pioneer Species
Climax Species
Ecosystems
In studying various sites over time, ecologists have seen gradual processes of change in ecological communities. In many cases, a community arising in a disturbed area goes through a series of shifts in composition, often over the course of many years. This series of changes is called ecological succession.
True
False
