pH range of 4.2 - 4.4

What is the pH range of acid rain?

edge effect

different environmental conditions that occur along the boundaries of an ecosystem

wet deposition

Acid materials that fall to the ground in the form of rain, snow, hail, sleet, or fog is known as _____.

since there were not enough sea lions and harbor seals to eat, killer whales started to eat sea otters the decline in sea otters led to an increase in sea urchins because there were not enough sea otters to eat the sea urchins and keep their numbers down -large sea urchin population fed on the kelp unchecked -kelp forest declined

Describe the circumstances that ultimately led to the decline of the Alaskan kelp forests. Put these in order (from top to bottom) in the correct order in which they occur.

the fast moving cars pose a risk to the animals trying to move across the roads

Identify a drawback for wildlife due to fragmentation caused by highways and roads.

-may be a cause of eutrophication in some water reservoirs -reduces oxygen levels of the water -can alter metabolic and reproductive rates in many fish and amphibians -organisms (kills them directly)

Identify four hazards of thermal pollution. Make sure to check only four items.

thermal pollution pesticides and chemicals in waterways acid rain eutrophication

Identify the four types of pollution we discussed in class.

-deforestation -roads and highways -fences

Identify three terrestrial reasons for habitat fragmentation.

-deforestation -urban growth and development

Identify two scenarios that would be examples of "habitat destruction".

turtles

The _____ are the most affected by highway and road fragmentation near wetlands and swamps.

fragmentation of habitat

The diagram below is illustrating _________.

bioaccumulation

The increase in the concentrations of harmful toxins within an organism is known as _____.

the edge effect

The light green areas are illustrating _______.

distribution of habitat

The picture below illustrates what type of threat to biodiversity?

sulfuric acid nitric acid

What are the two main types of acids found in acid rain?

biological magnification

What does this image show

wolves are attracted to the smaller sections and the prey (caribou) is more accessible and easier to hunt.....so the caribou populations decrease

What is the ultimate consequence for the caribou due to forest fragmentation in the tundra?

dry deposition

When acids deposit on Earth's surface in the form of dust or gases, it is called ______.

concentration is highest at the top (apex predator)

Where on the energy pyramid is the concentration of toxic chemicals the most when discussing biomagnification?

-Asian carp -Asian lady beetle -killer bees -zebra mussels -Fire ants

Which of the following are invasive species that have caused issues in the United States since 1957?

Eutrophication

Which of the following best describes the diagram below

acid precipitation formation

Which of the following best describes the diagram below?

pheasants

Which of the following organisms seems to do quite will in edge effect boundaries such as ditches along roads and railroad tracks?

Asian lady beetles Zebra mussels Fire ants

Which of the following would be considered invasive species?

as the rainwater falls it interacts with carbon dioxide molecules to form a weak acid called carbonic acid

Why is normal rainfall slightly acidic?

acid rain

caused by the burning of fossil fuels that releases sulfur dioxide into the atmosphere where it combines with natural atmospheric gases to produce acids

passenger pigeon

hunted for the food and were thought to be a threat to agriculture

elephants

hunted for the ivory in their tusks

ocelot

hunted for their beautiful furs

White Rhinoceros

hunted for their horns, which were used in some medicines

bison

hunted for their meat and hides

invasive species

non-native species that are either intentionally or unintentionally transported to a new habita

Define eutrophication

occurs when fertilizers, animal wastes, sewage, or other substances rich in nitrogen and phosphorus flow into waterways causing agal blooms

habitat fragmentation

separation of an ecosystem into small pieces of land by man-made barriers

thermal pollution.

sudden increase or decrease in temperature of a natural body of water by human influence

true

t or f: Disruption of habitat = when a habitat is altered so that one or more species are not able to use it.

overexploitation of a species

the excessive use of species that have economic value

biological magnification (or biomagnification).

the increasing concentration of toxic substances as trophic levels increase in a food chain or food web

true.

true or false:Destruction of habitat = when a habitat is no longer available to be used at all by any organisms.
