| Question | Answer |
|---|---|
| A geographically and genetically cohesive population that is separable from other such populations is called a/an ___________. | deme |
| Name an organism that's life history could be termed as iteroparious? | bear |
| Natural populations are controlled by density-dependent and density-independent forces. What is an example of a density independent factor? | volcanic erruption |
| This is defined as a role that a species in nature has distinct from those of other species? | niche |
| The maximum number of individuals of a species that an area can support is the _________________________ | carrying capacity |
| The carrying capacity of the environment is determined by | the limiting resource |
| What is the distinction between habitat and environment? | An environment is all of all conditions that directly affect the chances of its survival and reproduction which includes the space, forms of energy, and food sources. The habitat is different in that it is the physical space that the animal live in. |
| different species of birds that live in forests have shown that to avoid competition, the birds use the limiting resource in a slightly different way. This is known as? | a guild |
| Commensalism differs from mutualism by the fact that in commensalism? | only one organism benefits not both |
| In this type of defense potential prey can escape detection because their bodies match their background or resemble some inedible feature of the environment? | cryptic |
| Two species of caterpillar feed on the same corn. Upon inspection,two insects are found to be feeding on different parts of the corn Such observations led us to believe that no two species can occupy the same niche at the same time, a principle called | competitive exclusion |
| Predator/prey and parasite/host relationships are classically considered to be (answer using symbols like +, -, or 0) | +- |
| This type of defense is when animals are toxic or distasteful to predators and advertise their strategy with bright colors and conspicuous behavior? | aposematic |
| Name three groups of consumers. | herbivores, carnivores, decomposers |
| The energy storage in an animal's tissues is called ? | biomass |
| How much energy is lost or changed going from one trophic level to another? | 90% |
| Energy enters the ecosystem as ? | sunlight or hydrothermal vents |
| The organisms responsible for nutrient flow through an ecosystem are _________. | decomposers |
| We could state a biological "law" that all food chains begin with photosynthetic producers if it wasn't for the exception of (what organisms)? | chemoautotrophic bacteria |
| The majority of organisms exhibit the ________ grade of organization. | organ-system |
| The ____ plane is the imaginary plane dividing a bilateral organism into left and right halves. | sagittal |
| Bilateral symmetry is associated with ____, localization of sensory structures in a distinct head region. | cephalization |
| The study of tissues is known as | histology |
| Name a pseudocoelomate animal. | nematode |
| Blood, lymph, and tissue fluid are classified as _________ tissue. | connective |
| Name one of the four types of tissues. | nervous |
| Cnidarians are characterized by a _________ grade of organization. | cell-tissue |
| A fibrous protein that is particularly abundant in many types of connective tissues is | collagen |
| The scientific name of a mountain lion is Felis concolor and a house cat is Felis catus. Based on the names, you can determine that these two animals belong to the same: | genus but different species |
| Who is credited as being the Father of Taxonomy | Linnaeus |
| When writing a scientific name you must make sure to do what to the name? | underline |
| An _________________ includes all living organisms in an area and the physical environment with which they interact. | ecosystem |
| Exponential growth may be graphed (time versus population size) in a(n) shaped curve. | J |
| Orchids grow on large tropical trees. The orchids depend on the support offered by the trees, but do not harm the trees. Which term is most closely associated with this relationship? | commensalism |
| In a mutualistic relationship | both species benefit |
| Animals that only eat meat are called | carnivores |
| True or False: Fleas and lice are ectoparasites; lampreys and tapeworms are both endoparasites. | true |
| The energy storage in an animal's tissues is called | biomass |
| Predator/prey and parasite/host relationships are classically considered to be | +- |
| A ________ links trophic levels and depicts the transfers of energy and materials. | food web |
| Which of the following scientific names is correct A. Bos Taurus B. Bos taurus C. Bos taurus D. Bos taurus | C |
| The amount of space available to a rabbit would be an example of a _______________________ for the rabbit population. | limiting factor |
| The carrying capacity of an area for a plant is most likely determined by | availability of a raw material and energy |
| Which one of the following describes, in part, the niche of a rabbit? | rabbits are eaten by coyotes |
| Which would be an example of a density-dependent limiting factor? | The more mice there are on an island, the less food each has to eat. |
| True or False. The biotic component of an organism's environment is the non-living or physical factors. | false |
| Many plants (flowers) provide nectar for insects. The insects in turn pollinate the flower. This relationship between the insect and plant represents | mutualism |
| Which of the following would be at the highest trophic level? | a lion |
| The mountain lion is known by over 30 different common names. scientists saw the need to classify organisms with more detail in order to unify organism naming. As a result, Carolus Linnaeus came up with what method to specifically name each species? | Binomial nomenclature |
| Analyze the food web below. What role does bacteria have in the environment? | decomposing dead matter |
| Habitat can best be defined as | the place an organism lives. |
| A community | includes all organisms that interact with one another within a local area. |
| The diagram represents a pyramid of biomass in an aquatic environment. Which statement best explains why mass decreases from one level to the next in this pyramid? | Energy is lost to the environment at each level, so less mass can be supported at higher levels. |
| Which of the following organisms is a primary producer? | grass |
| Tapeworms living inside the intestines of their host are an example of what type of relationship? | endoparasitism |
| An animal that feeds on living material but does not kill the animal it feeds on is a | parasite |
| Energy enters the ecosystem as | light energy |
| An organism capable of reproducing more than one time during its life history is referred to as | iteroparous. |
| Approximately ________ percent of the energy available at one trophic level is converted into new biomass in the next trophic level. | 10 |
| The science of classifying living things according to their similarities is called: | taxonomy |
| Studies of different species of birds that live in forests have shown that to avoid competition, the birds will use the limiting resource in a slightly different way This is known as | character displacement. |
| Decomposers are primarily ________ and fungi. | bacteria |
