A testable explanation of a observation or problem is called _______________.
A hypothesis
Other than symbiotic relationship, what are two ways that organisms interact with one another.
Competition and Predator/Prey
What does a range of tolerance show?
Where an animal can and cant live because of limiting factors
The area where a population of organisms is found is called its __________
Range
Which of the following would hurt biodiversity; creating bridges over roadways, adding new species to an area, creating national parks?
Adding new species
When you design an experiment what you change/test is called ____________ and what you measure/watch/record is called _______________.
Independent Variable, Dependent Variable
What are the three ways to look at how energy moves in an ecosystem
Food Chain, Food Web, and Ecological pyramid
What stops trees from growing in Temperate grasslands?
Fire
What is a k-strategist or give an example of one?
An organism that puts a lot energy into its young, usually only has one or two babies at a time that are larger in size. (Elephant, Human, Horse)
Which of the following terms best fits with the problem pollution creates for biodiversity; fragmentation, biological augmentation, biological magnification?
Biological Magnification
When you sweat because it is hot, or shiver because it is cold this is..........
Maintaining Homeostasis
Give the three types of symbiotic relationships.
Mutualism, Commensalism, and Parasitism
What abiotic factor impacts why there are trees in the Boreal Forest/Taiga but not in the Tundra
Premaforst
What are the two types of growth models and what general types of reproductive strategies do organisms have for each type?
Exponential - r- strategists
Logistic - k- strategists
What are the two types of extinction, and how are they different?
Background - Slow gradual process/changes
Mass - Quick process that removes a lot of species
What are the 5 parts of the scientific method? (Team with the most correct will win the points)
Observation, hypothesis, experiment, collect data, analyze data.
List the 6 levels of organization from largest to smallest. (Team with the most correct will win the points)
Bioshere, Biome, Ecosystem, Community, Population, organism.
What are the three things that different in primary succession compared to secondary succession? (Team with the most correct will win the points)
1- Pioneer species (lichens and mosses)
2- Soil is created in primary and already there in secondary
3- Primary is slower than secondary
4 - Secondary comes from some natural disaster
List the two categories of limiting factors and give an example of each. (Team with the most correct will win the points)
Density-Independent (Fire, Natural Disasters, and weather)
Density-Dependent (Competition, Food availability, decease, parasites, and predation)
What are the three types of biodiversity? (Team with the most correct will win the points)
Genetic, Species, Ecosystem
Give as many of the Characteristics of life as you can. (Team with the most correct will win the points)
Has one or more cells, displays organization, grows/develops, reproduces, responds to stimuli, requires energy, maintains homeostasis, adapts/evolves.
What are the 4 biogeochemical cycles and give an identifying characteristic about each. (Team with the most correct will win the points)
Water - Least reliant on Biotic factors, involves (Transpiration, Condensation, Evaporation, Precipitation, and Percolation)
Carbon/Oxygen - Humans impact this cycle the most, a long term sink is fossil fuels) involves (Photosynthesis, and Respiration)
Nitrogen - Must have bacteria to do Nitrogen fixation and denitrification, Animals/Plants cant directly use Nitrogen in the atmosphere
Phosphorus - Only one not found in the Atmosphere, Has a long cycle (trapped in rocks and sediment) and short cycle (moving in soil, plants, animals and water).
What are the three zones of a lake and how would you describe them? (Team with the most correct will win the points)
Littoral - Near the shore with lots of light
Limnetic - In open water but with lots of light
Profundal - Deep open water with little light
What are the three ways to describe the dispersion or distribution of a population, and draw a representational picture. (Team with the most correct will win the points)
Uniform
Clumped
Random
What are the five threats to biodiversity? (Team with the most correct will win the points)
Overexplotation (Over use/take)
Habitat Loss
Habitat Fragmentation (Splitting a habitat)
Pollution
Invasive species (Adding new introduced species from somewhere else)
