Welcome to Ecology Biojeopardy!! Interact! 100 200 300 400 500 600 700 800 900 1000 How an Organism lives 100 200 300 400 500 600 700 800 900 1000 Population Population Density Growth and Dispersion 100 200 300 400 500 600 700 800 900 1000 100 200 300 400 500 600 700 800 900 1000 General Ecology 100 200 300 400 500 600 700 800 900 1000 100 Type of symbiosis where one individual benefits while the other individual is harmed (slowly) What is parasitism Continue 200 Occurs when one organism captures and eats another organism What is predation Continue 300 This is when two organisms fight for the same limited organisms What is competition Continue 400 Type of symbiosis that occurs where both individuals benefit What is mutualism Continue 500 The type of symbiosis that occurs when one organism benefits and the other organism is neither benefited nor harmed What is commensalism Continue 600 In the “Modeling Predation” lab, we modeled predation after an algal bloom and after a spawn. In our model, a __________was hunting for __________. What is heron, fish Continue 700 Certain species of mites will live on the bodies of flies (mostly for transportation). The mite makes flight more difficult for the fly and also affects its aerial hunting ability. This interaction is _________ What is parasitism Continue 800 Oxpeckers are birds that run over the backs of hippopotami and rhinoceroses. These birds rid their partners of injurious and annoying pests and in doing so obtain a ready supply of food. This is an example of _______________ What is mutualism Continue 900 Humans have Demodicids (eyelash mites) that feast on oil secretions and dead skin. We don’t know they are there. This is an example of ___________. What is commensalism Continue 1000 Name 2 examples of parasites What are tapeworms and Plasmodium (causes malaria) Continue 100 All of the biotic and abiotic factors that make up the area where a species lives What is habitat Continue 200 This is an example of both an abiotic and biotic factor in “your” environment: What is “1 living” and “1 nonliving”…answers vary Continue 300 An organism that eats many types of prey is a(n) _____________whereas an organism that eats just one thing is a _________________. What are generalist, specialist Continue 400 _________are organisms that do not regulate their internal environments (example: snakes). ______________use energy to regulate internal conditions. What is conformers, regulators Continue 500 3 events that happen in the Carbon Cycle What are respiration, photosynthesis, fossil fuels, etc. Continue 600 How energy flows from one organism to another in a food web. What is from producer to primary consumer to secondary consumer, etc. The decomposers return nutrients back to the soil Continue 700 This is one reason why it might hurt biodiversity if you move an “invasive species” into a habitat it doesn’t currently occupy What is “it could better adapt to the niche or have no natural predators…it could drive native species out or to extinction” Continue 800 The “piece of Earth” from the depths of the ocean to miles into the atmosphere where living things are. What is the biosphere Continue 900 One of the factors that makes up an ecological niche; the time of day a species is active as well as where it reproduces. What is behavior Continue 1000 In this part of the hydrologic cycle, water evaporates from trees (about 90% of the water). What is another name for this process? What is transpiration Continue 100 A measurement of the number of individuals living in a defined space What is population density Continue 200 Individuals may live in this kind of “dispersion pattern” if they are territorial or compete for the same resources often. (example is birds’ nesting habits) What is uniform dispersion Continue 300 In order to gain protection or help each other out more readily in accessing food and other resources, individuals within a population may have this type of dispersion. What is “clumped dispersion” Continue 400 The three-toed sloth is a solitary animal, and it has no competitors and few natural predators. It would most likely live in a __________ dispersion pattern What is random Continue 500 Organisms like birds, small mammals and reptiles show survivorship roughly equal at all ages of an organism’s life. This is which “Type” of survivorship curve What is “Type 2” Continue 600 Organisms like salmon have this type of survivorship What is Type III Continue 700 This is the type of information a survivorship curve shows What is the number of surviving members in a population over time. Continue 800 This is how population density and population dispersal are different What is population density measures the number of individuals in an area (not how they are grouped/spread out) Continue 900 This country has the highest population density What is Bangladesh at 2200 people/mi2 Continue 1000 Scientists might infer “this” about a deer’s habitat if the density of the deer population decreases over a given time. What is that resources may be depleted or community may have changed due to arrival of a new predator Continue 100 This is the type of growth that occurs when a population size increases dramatically over a period of time and there are unlimited resources (producing a J-shaped curve) What is exponential growth Continue 200 The movement of individuals out of a population into another population What is emigration (with an “e”) Continue 300 The maximum number of individuals of a particular species that an environment can support What is carrying capacity Continue 400 This is how birth rate and death rate are related right before biotic potential is reached What is birth rate is greater than death rate Continue 500 Parasitism and disease are examples of density _________limiting factors What is dependent Continue 600 The “kind of factor” that has the greatest effect in keeping the population numbers LOW for any given species What is a limiting factor Continue 700 The type of population growth that has limiting factors and produces an S-Curve What is logistic growth Continue 800 An example of a density independent limiting factor What is unusual weather, natural disasters, and human activity Continue 900 Net Primary Productivity What is GPP-producer’s respiration Continue 1000 A grasshopper feeds on meadow grasses. If a fire burns its field, resources are diminished, and carrying capacity is altered. What is one way carrying capacity could be increased for this population? What is (e.g. high raingrasses flourish!) Continue 100 The order of continents from most dense to least dense: What is Asia, Europe, South America, Africa, North America, Australia Continue 200 The human population is about _______billion, and it is growing in an __________fashion What is 7.5, exponential Continue 300 This type of ecosystem is characterized by very large temperature changes from mid-day to night. What are deserts Continue 400 A _________species is an organism that makes a dramatic impact on organisms in its environment What is keystone Continue 500 Three results of overpopulation (of humans) What are: overuse of fossil fuels, water and food resources. Continue 600 An example of a__________ is a vulture…it scavenges on dead or decaying matter What is a detritivore Continue 700 Organisms like the deep sea anglerfish usually live in this ocean zone that is without light. What is aphotic/abyssal zone Continue 800 The type of graph that shows percentage of individuals (both males and females) of certain ages. It allows us to see “rapid,” “slow,” and “zero” growth. What are Age Structures Continue 900 A location where permafrost is a permanent structure What is the tundra Continue 1000 A lichen is an example of a pioneer species. But “this” is what a lichen has to do with “symbiosis” What is a lichen is two different species (algae conducts photosynthesis and fungus collects water) Continue
