Type of growth: Exponential Type of growth:LogisticalUnit 2 Test Review Questions (DUE MONDAY)What has the population reached when it flattens out?Carrying Capacity2. Use the following information about a frog population to calculation the new population size in 2015. In 2014 there were 214 frogs. With in the year 36 were born and 47 died. 20 frogs decided to leave the area but 15 new frogs joined the population. What is the new population size in 2015? (show your calculation setup AND answer).(36+15)-(47+20) = 51 – 67 = -16 New population 214 – 16= 1986. What is the difference between primary succession and secondary succession?Primary succession starts with no soil, only bare rock, it occurs after new land is formed from a lava flow or a major landslide/flood. Pioneer species is lichen.Secondary succession has soil to begin with and often caused by forest fire, floods. Pioneer species mosses and small plants.Clumped uniform Random5. Population distribution: Label the images below with the correct term for the type of distribution.4. Label each organism in the food chain with the correct term for its “role”.-3064931577340297010714926733. Compare the frog population size in 2014 and 2015. What is the percent change in the population?(16/214) x 100 = 7.5% decreaseTop carnivoreomnivorecarnivoreherbivoreherbivoreherbivorePrimary producer (autotroph)7. What are the four ways the evolution of a population can occur:Mutation, migration, genetic drift, natural selection, artificial selection8. What are the THREE conditions that must be present for Natural Selection to occur?More offspring produced than can survive, individuals of a species vary in traits, individuals vary in their fitness.9. Three species of birds live in the same tree. One species spends its time near the bottom gathering food, another gathers food from the center of the tree and the other gathers from the top of the tree. This division of the food gathering area is called Resource partitioning10. Species interactions: Write the correct term for the following descriptions. (see Ch 5, Lesson 2)parasitism A close relationship between two different species where one is harmed and one is helped.Coevolution Two species evolve together over time, changing together.Predation One species hunts, kills, and consumes mensalism For example, a owl nesting in a petition Two or more organism tying to use the same resource.Mutualism A close relationship between two different species where both benefit.Herbivory A grasshopper eating a plant.320040156210Tropical dry forestTropical Rain forest11. Biomes: Fill in the chart that shows the basic biomes based on the amount of precipitation and the temperature in the region.SavannaTemperate forestChaparralTemperate rain forestTemperate grasslandBoreal forestDesertTundraOpen ocean zoneIntertidal Neritic zone12. Label the regions of the ocean and lake below.Littoral zoneLimnetic zonePhotic zonephotic zoneAphotic zoneBenthic ZoneAphotic zoneBenthic zone13. Write the taxonomic groups in correct orders starting with Domain:Domain, kingdom, phylum, class, order, family, genus, species14. What are the four threats to biodiversity?Habitat change and loss, Invasive species, pollution, climate change, overharvesting15. What is the US laws that protects biodiversity? Describe what is does.Endangered species act 16. What are two species approaches to protecting biodiversity?Single species approach – captive breeding , cloning, species survival plan17. Define the following terms:extirpation: species dies out in certain area, but is still found on the planetendangered species: _species that is in danger of becoming extinctpoaching: illegal capture or killing of an organismendemic: species found in one area but no place else ................
