What would be true if the rabbit population increased?
The bacteria population will decrease
The hawk population would increase
There may be increases in wolves, hawks, and snakes.
Grasshopper populations would increase
What could be changed about the food web to make it more accurate?
Remove bacteria because they are not in the forest
Change arrows to go in opposite direction
Show arrows going from all organisms to fungi and bacteria
Draw arrows from the Sun to all organisms
Prairie dogs live in complex tunnels underground and compete with other herbivores in the ecosystem. Which is the abiotic factor in this situation?
Prairie dogs
Underground habitat
Other herbivores
Grasses
Which abiotic factor(s) do plants compete for in order to make their own food?
water ONLY
sunlight ONLY
wind ONLY
water AND sunlight
Which is NOT an example of an abiotic factor?
Sunlight
Wind
Fungi
Water from a stream
Which is a true statement?
Biotic factors only rely on abiotic factors to survive.
Abiotic factors include all living things in the ecosystem.
Abiotic factors include sun, water, and plants.
Biotic and abiotic factors are both necessary for a sustainable ecosystem.
Which is the most likely outcome to the organisms in an ecosystem near the site of a nuclear disaster?
Organisms could develop mutations in their DNA
Animals will move to another location
All animals will become extinct
Animals will be impacted but plants will not
What is the most likely adaptation for a rabbit population which once lived in the snow but now lives in shrubs and rocks due to increased global temperatures?
They will see an increase in fur production
They will become better swimmers
They will grow longer ears
Their coats will be darker
Controlled forest fires are often used to clean up the underbrush of an ecosystem to promote a healthier ecosystem. How would they impact the organisms in the ecosystem?
Organisms may have to temporarily move
All organisms will die in the fire
Only plants and trees will be impacted
All organisms will increase in population in the first month after the fire
How are phytoplankton similar to small trees?
Both grow in soil
Both conduct photosynthesis
Both are about the same size
Both are at the top of the food chain
Which is MOST likely to happen if a large number of phytoplankton are killed from runoff entering the ocean?
The number of zooplankton would increase
The number of salmon would probably decrease
The number of porpoises would probably stay the same
The Sun would probably not emit as much energy
What conclusion could you make based on the graph?
Nitrogen is NOT a problem in the Gulf of Mexico
Corn and soybeans are the only sources of Nitrogen pollution
Most nitrogen pollution found in the Gulf comes from farming crops.
Nitrogen that comes from the atmosphere is most harmful.
Which relationship is true according to the food web?
Phytoplankton prey on crayfish
Flamingos are predators of crayfish
Shrimp get nutrients from zooplankton
Shrimp have three predators.
How does biodiversity help an ecosystem?
There are many types of foods if one becomes unavailable
Organisms can move around a lot
Organisms eating food will die and more will eat the food
Trees grow taller to compete for -
soil
air
sunlight
good temperature range
