Semester 2: Unit 4 Biodiversity
Directions: Please fill out this study guide with the correct answers using your lessons as a source of help. Once completed, you will upload this to your sample work Dropbox for the corresponding unit.
Match the following terms with their definitions:
Community (U4L5) Systematist (U4L2) Abiotic (U4L4)
Taxonomy (U4L2) Carrying Capacity (U4L4)
Ecosystem (U4L5) Biodiversity (U4L4) Biotic (U4L4)
Word
Definition
1: The variety of life within a species, a community, or an ecosystem
2: All the organisms living in an area
3: Scientists who specialize in taxonomy
4: Elements in an ecosystem that have never been alive
5: A branch of science concerned with naming, classifying, and describing the relationships between all living things on Earth
6: Any living or once-living things in an ecosystem
7: All the living organisms in a given area along with the nonliving things with which they interact
8: The maximum number of individuals of a particular species that an ecosystem can support at a given time
Answer the following questions/statements (each number should have a response):
Place the following levels of classification (Linnaean system) in order from largest/most general group to smallest/most specific group. (1=largest - 8=smallest) (U4L2/3)
____ Phylum
____ Species
____ Kingdom
____ Class
____ Genus
____ Order
____ Domain
____ Family
Fill in the following table about the 3 domains into which all living things are classified. (U4 L2/3)
Domain
Nucleus (yes/no)
Habitat
Representatives
Bacteria
Archaea
Eukarya
1: Why do scientists use taxonomy? (U4L2)
2: True/False: Eukaryotes(eukarya) are the only domain that can be further classified into kingdoms. (U4L3)
3: What is the difference between a population and a community? (U4L4)
4: What factors can impact the carrying capacity of an ecosystem? (U4L5)
5: Define interspecific competition and give an example. (U4L10)
6: What type of events can lead to the formation of a new ecosystem? (U4L14)
7: A tree falls over in a thunderstorm. Would this be an example of a light/temporary disturbance or a permanent disturbance to an ecosystem? (U4L13/14)
Essay Questions (The following questions are VERY similar to what you will see on your test. They are NOT required for points on this study guide, but it would be very beneficial to familiarize yourself with them and use them to prepare for the test!!):
Yes/No (I know this and can explain to a friend.)
Essay Question
Be able to analyze a graph and identify factors that may be impacting the populations shown on that graph. (specifically carrying capacity and how two populations may be impacting each other and why?) (U4L6)
Give an example of a severe weather event and explain how it created ecological disturbances that impacted biodiversity. (U4L13)
If you were designing a novel species that would be introduced into an ecosystem with the sole purpose of causing as much damage as possible, what abilities and characteristics would you give this species and why? (U4L12)
Why are lichens necessary to establish a new ecosystem after an extreme disturbance? (U4L14)
**If you answered “no” to any of the above essay questions, I highly suggest you contact your teacher to get help before the test.**
