Survivorship curves - Study guides, Class notes & Summaries

Ecology - -The study of how organisms interact with one another and with their physical environment - Organism -> population -> community -> ecosystem -> biosphere - Binomial: scientific name Biotic Abiotic - - Biotic: living, or once living, factor in an ecosystem - Abiotic: non-living factor in an ecosystem Organisms Species Population - - Organisms: an individual living thing - Species: a group of similar organisms that can mate and produce fertile offspring - Populatio...

Survivorship of which of the following organisms is most likely to be analyzed with a static life table? A. Butterfly B. Annual Plant C. Elephant D. American Robin E. Barnacle CORRECT ANSWERS: C. Elephant _________ survivorship curves are usually associated with organisms that have high mortality rates in the early stages of life. CORRECT ANSWERS: Types III If the net reproductive rate (Ro) is equal to 0.5, what assumptions can we make about the population? CORRECT ANSWERS: This po...

BIO 106 Final Exam Study Guide Thinking about the nutrient cycles learned in the Ecology lectures, what are the key nutrients? - ANS Carbon, Nitrogen, Phosphorous From which reservoir do plants obtain each these nutrients? Where/how do animals obtain these nutrients? - ANS Carbon - reservoir - fossil fuels, soils, sediments of aquatic ecosystems, oceans, plant and animal biomass, the atmosphere (photosynthesis) Nitrogen - reservoir - 78% atmosphere, soils and sedimen...

In the case of mutant and wildtype simploids, who overtook the other? mutant overtook the wildtype since they matured and reproduced earlier Once nutrients and energy are acquired w at determines where it will go? environment- can go to growth and reproducing or it can go towards defense 00:13 01:28 With the tits, what was confusing? the mean of eggs was 5 but when 12 were laid it produced the most surviving which is confusing since the mean should be the most survivin...

Apes Unit 3 Exam review, 100% Accurate, rated A+. latest updates. Population Distribution - -Clumped - Groups of Populations Uniform - evenly spaced Randome - Randome populations Type 1 Survivorship - -ex: Humans, survivorship curves are for species that have a high survival rate of the young, live out most of their expected life span and die in old age. Type 2 Survivorship - -survivorship curves are for species that have a relatively constant death rate throughout their life span. ...

AP Biology Unit 8: Ecology climate - The long-term prevailing weather conditions at a given place. abiotic - Nonliving; referring to the physical and chemical properties of an environment. biotic - Pertaining to the living factors—the organisms—in an environment. biomes - Any of the world's major ecosystem types, often classified by temperature and precipitation disturbance - A natural or human-caused event that changes a biological community and usually removes organisms fro...
