Zebra Mussels______

Dreissena polymorpha: are invasive to the Great Lakes and cause competitive exclusion

If climate warms significantly, tundra permafrost may melt. This may next lead to_____of the Community

Succession

Which of the following might be first to populate an area after permafrost melts in response to global climate change?

Plants or lichens(fungi and algae)

Intense hurricanes that may result from global warming can directly lead to_____within communities

Succession

Global warming has been hypothesized to cause many plants to flower earlier. If bees search for food earlier in response to this, this would represent_____within the community

Resilience

The relationship between flowering plants and bees is best described as_______

Mutualism

.Global warming has been hypothesized to cause many plants to flower earlier. If caterpillars that feed on oak tree flower buds do not adjust to the earlier oak tree bud burst and subsequently starve, this represents_______

Resistance

The relationship between flowering plants and caterpillars is best described as______

Herbivory

Individuals of a single species fighting over access to a limiting resource is an example of_______

Intraspecific competition

Zooplankton populations in Lake Erie and the Hudson River have declined by up to 70% since the arrival of zebra mussels because________

They increased filterfeeding in the community leading to loss of photoplankton for the zooplankton to eat

By definition, parasites_________their host

depend on and slowly harm

Orchids require tree limbs for support but do not harm the trees. This demonstrates_______

Commensalim

________capture solar energy and use photosynthesis to produce sugars

producers/autothrophs

Grazing animals such as deer are________

Primary consumers

Zooplankton-eating fish are_______

Secondary consumers

Which of the following is true about top predators?

They are keystone species and control populations of herbivores which without them would multiply and negatively affect the plant community

Secondary succession_______

A disturbance(succession) in which not all life dies and vestiges of the previous community remain to shape the next community

_______argued that communities are temporary associations of individual species that can reassemble themselves into different combinations

Henry Gleason

A climax community always_______

Remains in place with little modification until some disturbance restarts the succession

Herbivory is a type of _______

Preditation: One organism benefits off of eating the plant

Benthic organisms in the Great Lakes______

Have in creased by 10% since the arrival of the zebra mussels

Mircobes in our digestive tract that helps us digest food demonstrates a(an)_________association

Mutual

Which of the following are pioneer species?

First to colonize an area. usually fungi and algae known as lichens

Techniques to eradicate zebra mussels_______

ships have to dump their freshwater ballast at sea before entering the great lakes

Efforts at urban restoration_______

Attempt to undue damages done to communtiy due to urban developments

Kelp_____

provides complex structures for fish and invertebrates to live and find food

Environmentally and economically acceptable means of controlling introduced invasive species include_____

preventing rather than controlling

Global climate change may produce major shifts in biomes for any given location because______

it affects communities due to climate change

The Everglades Restoration Plan in Florida_______

re-watering dried out wetlands caused by flood protection actions. $7.8 billion project

Define the term invasive species and give two examples from your textbook

A species that is accidentally or intentionally introduced into a new environment. Zebra mussels and Quagga mussels

Give an example of how an invasive species can cause ecological or economic harm

An invasive species can destroy the trophic levels by over-consuming organisms that can cause a trophic cascade. Prevention of these species can be economically harmful

Briefly explain the National Invasive Species Act

Passed by Clinton in 1996 for protection and control of invasive species in aquatic biomes in the Pacific Coast

Briefly explain ecological restoration of the Great Plains

Native species are being replanted and invasive species are being controlled

Briefly describe the factors that determine characteristics of aquatic biomes

Water temperature, salinity, dissolved nutrients, wave pattern, depth and substrate

Briefly describe what is meant by a pioneer species

a species which is first to "civilize" and area after a primary succession

Removal of a _______from an ecological community has particularly strong or far-reaching impact on food webs

Keystone species

. ______, such as soil insects and millipedes, are consumers of nonliving organic matter

Detrivores

When multiple organisms seek the same limited resource, their relationship is said to be one of _______

Competition

What ecological traits do successful invasive species possess? How do these traits interacts to make controlling them difficult

Invasive species are extremely adaptable and can reproduce qickly. This makes them very hard to control

Why do environmentalists favor the term food web as opposed to food chain?

Food chains are linear and cannot represent the detail and relations that a food web can

List 3 major trophic levels in a food web. What types of organisms are found in each level? Where are the autotrophs and heterotrophs found? Discuss the significance of each level for the integral functioning of the food web

producers are autotrophes such as grasses and plants, primary consumers eat the producers and are heterotrophs like insects and bugs and secondary consumers eat the primary consumers and are also heterotrophs like bunnies and birds.

Discuss ways to control invasive species

Manual removal, toxic chemicles, drying out, depriving of oxygen, stressing with heat, sound, carbon dioxide and ultraviolet light

Discuss the interrelationship between great whales, orcas, sea lions, sea urchins, and kelp in the Pacific Ocean

Sea otters are keystone species that each the urchins to ensure they don't over eat all the kelp which is a huge part of that aquatic biome. The killer whales eat the otters which then allows the urchins to thrive which destroys all the kelp.

Dicuss the difference between intraspecific and interspecific competition

Intraspecific is competition between the same species. Interspecific is between two or more species
