10.
The food webs below model relationships among the organisms in two ecosystems. Which ecosystem would be more likely to survive if a disease killed the grass?
a)
The forest ecosystem, because most of the animals can eat othe organisms.
b)
The grassland ecosystem, because several predators compete for food
c)
The forest ecosystem, because it has three top predators
d)
The grassland ecosystem, because it has many herbivores
11.
The Guam rail is a flightless bird found on the island of Guam, It builds a shallow nest on the ground and lays eggs throughout the year. There are no native species of snakes on Guam, so the Guam rail had no experience with snake predators until the brown tree snake was accidentally introduced sometime between 1944 and 1952. These snakes, which eat a wide variety of animal species, quickly extablished a large population on Guam. How was the Guam rail most likely affected by the introduction of the brown tree snake?
a)
The brown tree snake ate only species that lived in trees, so it had no effect on the Guam rail.
b)
The Guam rail quickly developed the abiltiy to fly in order to escape from the brown tree snake.
c)
The population of the Guam rail declined, and the species nearly became extinct.
d)
The Guam rail began to build its nests in trees.
12.
Many Texas caves provide a habitat for animals that live in total darkness. The caves are damp and cool, and most of the caves are rich in the mineral calcite.

a)
Owls are predators of bats, and bats are predators of moths.
b)
Beetles compete with bats and cave spiders.
c)
Snakes prey on bats and owls.
d)
None of the above
13.
