Increasing biodiversity affects the sustainability of an ecosystem by.
always decreasing competition for limited resources within an ecosystem
Allowing an ecosystem to survive many changes
Preventing an ecosystem from surviving many changes
Always increasing competition for limited resources within an ecosystem.
Which of the following describes a behavior or physiology that would help an organism survive the change in seasons?
Bears hibernating in winter
Geese migrating south for the winter
Tulips developing enlarged bulbs that store food
All of the choices are correct
Plants contain xylem tubes for transporting water from roots to the top of plants. Low growing plants such as mosses lack xylem tubes. Xylem is an important adaptation because -
xylem prevents food from going where it is needed in the plant
it keeps plants from losing their leaves in the winter
plants that have it do not have to carry on photosynthesis
plants can grow taller to compete for sunlight.
Organisms have gradually adapted certain structures that help them succeed in their environments. What internal structure have birds developed that helps them succeed in their environments?
Oil glands for flight endurance
Pointed beaks to increase chances of attracting a mate
Hollow bones to reduce mass for flight
Webbed feet for landing on tree limbs
The bulk of these short-grass prairie plants in underground. The main benefit that these plants receive from this adaptation is -
More surface area for the absorption of water
more resistance to insect-transmitted diseases
increased ability to maintain cooler leaf temperatures
improved ability to detect areas high in carbon dioxide
The diagram above shows the land surface changes created by a river flowing through Hill country over many years. What process caused the changes?
Condensation
Erosion
Deposition
Evaporation
A certain kind of plant lives only in a small area of a tropical rain forest. What can you conclude?
Not all parts of a tropical rain forest are the same
A tropical rain forest does not have many types of plants
A tropical rain forest does not have many types of animals
All parts of a tropical rain forest are the same
The plateaus shown above have been worn down by wind and rain. The breaking down of rocks and other earth materials is called.
Evaporation
Condensation
Weathering

Which of the following sequences MOST likely represents ecological succession on a recently abandoned wheat field?
Native trees-shrubs-flowering plants-grasses
Grasses-flowering plants-shrubs-native trees
Shrubs-grasses-native trees-flowering plants
Flowering plants-native trees-shrubs-grasses
Ecosystem 1: 20 animal species, 50 plant species
Ecosystem 2: 130 animal species, 400 plant species
Which system can sustain life after a flood?
Ecosystem 1 survives because it is small and less affected by natural disaster
Ecosystem 1 survives because it doesn't receive as much precipitation, so the flood will be a welcome water source
Ecosystem 2 survives because it has a lot of biodiversity, which allows it to better withstand natural disasters.
Ecosystem 2 survives because of its average temperature.
What is a heterotroph?
Organism that makes its own food
Organism that eats other organisms to obtain food
What is an autotroph?
Organism that makes its own food
organism that eats other organisms for food
An organism with a nucleus is a(n)
Eukaryote
Prokaryote
an organism without a nucleus is a(n)
Prokaryote
Eukaryote
