Ecosystem Review

Which claim best explains the effect of the increase in grass in the fox population?

• The number of prey animals would decrease which would decrease the predator population.

• The number of prey animals would decrease which would increase the predator population.

• The number of prey animals would increase which would decrease the predator population.

• The number of prey animals would increase which would increase the predator population.

What type of community would we most likely expect in this ecosystem?

• alligators, crawfish, cypress trees, ducks, frogs, mosquitoes, water snakes

• bats, cacti, coyotes, rattlesnakes, spiny lizards, jack rabbits

• beaver, black bear, cardinals, deer, pine trees, shrubs, squirrel

• bison, coyotes, deer, hawks, mice, rabbits, shrubs, prairie dogs

Which of the following shows one of the ways energy can flow according to this model?

• Sun → Plants → Mouse → Decomposers

• Snake → Hawk → Decomposers → Plants

• Plants → Hawk → Snake → Decomposers

• Decomposers → Sun → Plants → Mouse

In what way might a decrease in the Fish population most likely impact this ecosystem?

• The Seagull population will now get its energy from Krill.

• The Zooplankton population will go extinct.

• The Seagull population will decrease.

• The Leopard Seal population will increase.

Which of the following ecosystems is best described by the abiotic factors presented in the data table?

• Desert

• Grassland

• Forest

• Wetlands

Which of the following claims can be argued best from the data?

• Rainforests need less water than deciduous forests.

• Grasslands need less water than deserts.

• Forests need less water than grasslands.

• Grasslands need less water than forests.

Which of the following communities is best adapted to survive in a grassland ecosystem?

• beaver, black bear, cardinals, deer, pine trees, shrubs, squirrels

• bison, coyotes, deer, hawks, mice, rabbits, shrubs

• bats, cacti, coyotes, hawks, owls, rattlesnakes, spiny lizards

• alligators, crawfish, cypress trees, ducks, frogs, mosquitoes, water snakes

Southern live oaks are commonly found in the Southeastern United States, mainly along the coastal plains. They have thick bark, shiny green leaves, and produce acorns. The Southern Live Oak is something of an iconic image of the South, with thick draping’s of the Spanish Moss plant growing on its branches. These trees can grow to 60+ feet tall, with branches stretching out over 80 feet.

Based on the description above, the southern live oak would best be classified as a:

• predator

• parasite

• host

• herbivore

The sponge mushroom would be classified as a _____ based on how it obtains its energy.

• producer

• consumer

• decomposer

• host

What would most likely happen to the community represented by this food web model if Large Piscivorous Fish were to die out in the Chesapeake Bay habitat?

• Osprey would no longer have a food source and might go extinct.

• Gulls and Terns and Wading Birds would eat less Small Planktivorous Fish.

• Wading Birds would become the chief food source for the Bald Eagle.

• Bald Eagle numbers would increase.
