Sustainable living

The lifestyle that attempts to reduce an individuals or society use of earth natural resources and personal resources.

What does recycling mean? why should someone recycle?

to convert waste into reusable material

It keeps the world a healthy place

what is the pacific garbage patch?

the gyre of marine debris particles in the central North Pacific. It is not possible to help

Define 2 biomes of the world, define an ecosystem found in each and explain the Biotic and Abiotic factors involved.

Grasslands- lands dominated by grasses

Very hot summer and very cold winters

Abiotic factors- climate temperature

Deserts- ares of land that are pretty much always dry

Hot all year around

Abiotic Factors- Climate, temperature

Choose any Biome; create a food chain defining the primary producer, primary consumer, secondary consumer, tertiary consumer, quaternary consumer, herbivore, omnivore, carnivore, scavenger, and decomposer

What are dead zones in the gulf of Mexico? What causes it? What can stop them?

A hypoxic areas in the world oceans or lakes. (no Oxygen)

Nutrient Pollution from humans

Stop polluting

What are keystone species? top predators? not to predators?

a species on which other species in an ecosystem largely depend

Top predators-jaguar

Not top predators- Sea otter

define competitive exclusion? 2 examples

the inevitable elimination from a habitat of one of two different species with identical needs for resources.

red squirrel grey squirrel

Define the following terms and give 2 examples of each

a. Coexistence- to live with or close to another usually in peace. two plants growing side by side

b. Parasites- an organism that lives through another one. Tapeworms, fleas

c. Mimicry- the close external resemblance of an animal or plant. bees

d. Mutualism- symbiosis that is beneficial to both organisms involved. Zebra, birds

e. Commensalism- an associtaion between two organisms. Cattle, Ducks

Explain the Carbon Cycle and how do humans affect this cycle?

the series of processes by which carbon compounds are interconverted in the environment, chiefly involving the incorporation of carbon dioxide into living tissue by photosynthesis and its return to the atmosphere through respiration, the decay of dead organisms, and the burning of fossil fuels.

Humans affect the cycle because we mess with the environment by taking out trees and plants

What is global dimming? Where does it usually affect and why is it a problem?

the decrease in the amounts of solar radiation reaching the surface of the Earth

The surface of the Earth

Its not good for the environment

Explain the Greenhouse Effect. How do the carbon cycle and the greenhouse effect go together?

the trapping of the sun's warmth in a planet's lower atmosphere due to the greater transparency of the atmosphere to visible radiation from the sun than to infrared radiation emitted from the planet's surface.

The greenhouse effect is increased when carbon dioxide is released into the atmosphere.

Define endangered species and give an example. How does a species become endangered? What if this species was a keystone species? What would happen to the current ecosystem? Why should humans care about the endangered species?

species which has been categorized by the International Union for Conservation of Nature Red List as likely to become extinct.

threats from changing environments or predators are considered threatened

If it was a key stone species that would be a big problem

the current ecosystem would be messed up

We should care because some animals are very important to the environment

define invasive species, give 2 examples how do they affect the ecosystem they are now invasive too. How did the invasive species arrive to their new ecosystem?

organisms that aren't native

Black rat

cotton white fly

The black rat destroys everything

and the cotton fly repopulates really fast

At one time rainforest covered 14% of the Earth’s land surface; today rainforest only cover 6% today; why should a person care about the lost rainforest ground? Why are the rainforest being cut down? What would happen if they all disappeared?

The lost rainforest helped animals to survive and if we keep taking it away

They are being cut down for housing and cities \

We would lose a lot of animals

Why is human overpopulation a major concern? Explain all the resources needed for a human to sustain life.

Because if there is to much people we wont have enough food or resources and people will start dying

food, water, shelter, sunlight

Pesticides- what are they, how do they adversely affect the environment, and how does this create problems with the genetic diversity in crop production.

toxic substances released intentionally into our environment to kill living things

they kill weeds and possibly other things it touches but is not suppose to

It could kill the crops if it isnt suppose to be put on

Interpret this quote. “If the bee disappeared off the face of the Earth, man would only have 4 years left to live.” Maurice Maeterlinck, The Life of the Bee

we need bees to survive

It is the year 2070 and you are having a conversation with your grandchildren about how the environment has changed since you were young- give a prediction of how the Earth would look to them.

There would be no forests or rain forests because of the population and the technology would find other ways to live with out the use of trees
