Trap heat inside our atmosphere
Keep out sunlight
Keep plants growing
What is the main cause of air pollution?
plowing fields and releasing dust
using solar power
burning fossil fuels
using water power
Climate change caused by extra carbon dioxide in the air that causes heat to get trapped in the atmosphere is called
global warming
photosynthesis
smog
A mixture of smoke, fog and chemicals in the air is known as ________.
oxygen
radiation
smog
What are ways that we can decrease air pollution?
carpool
conserving electricity
follow laws made by the EPA
burning extra fossil fuels
What is biodegradable waste?
Materials can be decomposed by microorganism.
Materials that can not be decompose by microorganism.
Material that can decomposed to nutrient that can be absorbed into the soil.
Material that can not be decomposed.
Choose the waste material that is biodegradables waste.
Plastic waste that can be found in the ocean or in the land takes hundreds of years to decompose and disintegrate naturally. This means that plastic is a type of waste _____
Biodegradable waste
Non-biodegradable waste
How do landfills effect the environment?
Landfills cause fish to be poisoned and die
Landfills support plant growth and heatlhy soil
Lanfills cause smog in the air
Landfills cause chemicals from trash to absorb into the soil and harm plants
Which is one reason that trash and litter can hurt wildlife?
Wildlife are afraid of human garbage.
Trash covers the scent of other animals they are hunting.
Wildlife may try to eat plastics and choke on them.
Trash and litter removes their camouflage.
What is an effect of land pollution?
no clean drinking water
loss of habitat for animals
diseases from breathing in poor quality air
What is the largest cause of land pollution?
Animal waste
Plants decomposing
Human actions
What are examples of toxins? (3 answers)
water
salt
pesticides
mercury
insecticides
Which organism would have the most bioaccumulation?
grass
rabbit
snake
hawk
Which organisms are most affected by bioaccumuation?
Top predators
Producers
Primary Consumers
Herbivores
How does biomagnification put a top predator at a disadvantage?
Food is much harder to find the farther up the food chain you go.
Toxins and chemicals accumulate in the bodies of everything that was eaten by the food that you eat.
Toxins and chemicals bind to the tissue of larger animals better than smaller ones.
The loss of energy up the food chain is directly proportional to the amount of toxins taken up by the body.
What is the original cause of eutrophication?
Too many predators
Too many herbivores
Excess fertilizer
Too much oxygen
How does eutrophication cause the death of aquatic organisms
the build up of carbon dioxide in the water
the lack of nitrogen in the water
the lack of carbon dioxide in the water
the lack of oxygen in the water
In eutrophication, dissolved oxygen levels decrease because
bacteria use it as they decompose organic material
algae uses it during photosynthesis
it reacts with hydrogen to form H2O (water)
fish use it up as they consume algae
When algae levels increase in a body of water, it
cuts off light to plants at the bottom.
increases light to the plants on the bottom.
causes dissolved Oxygen levels increase.
causes bacteria populations decrease.
