The picture shows a river in a desert environment.Which quality of this river plays the largest role in allowing for the abundant vegetative plant growth along the river's bank?
The river maintains a significantly lower temperature than the rest of desert.
The river attracts animals that feed on grasses and shrubs along the river.
The river provides the moisture required for plant growth in an arid environment
The river erodes sediments that get in the way of root growth down the river.
The picture shows cacti growing in a desert environment.
Which of the following is NOT a way that a desert environment supports populations of cacti?
It has fewer plant-eating organisms than other environments.
It has a lot of sunlight for the cacti to photosynthesize during the day.
It has loose, sandy soil for cacti to bury their shallow roots in easily.
It has little rainfall throughout the year.
The picture shows a mangrove estuary environment.
Which of the following is a quality of the mangrove estuary environment that allows small fish and crustaceans to live there?
It provides shelter and protection from predators for small animals.
It has a fast-moving current and waves running through it.
t has a higher salt content than ocean water.
has lower-than-normal oxygen levels because of the mangrove trees.
The food webs model relationships among the organisms in two ecosystems.
Which ecosystem would be more likely to survive if a disease killed the grasses?
The forest ecosystem, because most of the animals can eat other organisms.
The grassland ecosystem, because several predators compete for food.
The forest ecosystem, because it has three top predators.
The grassland ecosystem, because it has many herbivores.
The figure above shows the same ecosystem in Texas at two different times.
Which of the following MOST likely caused the change of species shown in the figure?
development of a parking lot
passing through of a glacier
preservation of habitat
occurrence of a forest fire
Which of these types of environments is MOST LIKELY to
experience the arrival of pioneer species?
an old growth forest
an undisturbed prairie
an established mountain lake
a newly formed volcanic island
Which of the following would most likely be true about ecosystems where factors such as light and water are not restrictive?
The ecosystem will contain an abundance of all the same type
of producers.
The ecosystem will have a hard time sustaining any consumers.
The ecosystem will contain too many consumers.
The ecosystem will contain an abundance of a variety of producers.
Clownfish, sea anemone, coral, sea urchins, sponges, and parrot fish are just a few examples of the large variety of organisms that can be found in a coral reef. The coral reef and its inhabitants are suffering due to several factors such as pollution, coastal development, sedimentation and destructive fishing practices.
What would be the most likely result if some of the species in the coral reef are destroyed?
Other organisms would move into the coral reef area.
The coral reef would be allowed to flourish without so many fish and plants living in and around it.
The coral reef would begin to deteriorate without the variety of fish and plants necessary to maintain balance.
The coral reef would begin to deteriorate without the variety of fish and plants necessary to maintain balance.
Directions: The tables show the number of species and organisms in four different ecosystems. Use the tables to answer any questions that follow.
Ecosystem Q
Ecosystem R
Ecosystem S
Ecosystem T
Based on the table, which of the following is most likely true?
Ecosystem Q will sustain itself longer than Ecosystem T, because Ecosystem Q has the least amount of organisms to support.
Ecosystem R will sustain itself longer than Ecosystem T, because Ecosystem R has a more even distribution of organisms.
Ecosystem S will sustain itself longer than Ecosystem R, because Ecosystem S has more organisms in total.
Ecosystem T will sustain itself longer than Ecosystem Q, because Ecosystem T has a more dominant species in its environment
Which statement is an essential characteristic of reptiles and birds that are primarily terrestrial and reproduce on land?
They have soft bodies covered with hair or fur.
They have leathery or hardshelled eggs.
They have 4 appendages and can move about swiftly.
They must be primary consumers.
Functions of animals that help them survive in their environment are —
structural adaptations
modifications
physical characteristics
behavioral adapatations
The pictures show a rain forest tree canopy on the left and a toucan that lives in this tree canopy on the right.
Which of the following is NOT an explanation for why this rain forest tree canopy supports populations of toucans?
It has trees with fruits for food.
It has tall plants to stay above ground predators.
It has a lot of sunlight to stay warm.
It provides many places to nest and reproduce.
If you eat a ham and cheese sandwich with lettuce and tomatoes, where would you be placed on the food chain?
producer
primary consumer
secondary consumer
tetiary consumer
The picture below shows an Arctic environment, on the left, and a ring sealed pup, on the right, that lives in this Arctic environment. Ring seals often give birth and raise their young on fast ice, ice that forms in the ocean and is not attached to land.
This Arctic environment supports the ability for ring seals to have young by providing fast ice that does all of the following for the ring seals EXCEPT —
give rings seals a tower to see far away and spot polar bears.
give ring seals a landing place out of the water.
keep ring seal pups away from land predators that can't swim.
let ring seals hunt for fish near their pups.
Use the desert food web above to answer the following question:
How is this ecosystem MOST likely to be affected by a sudden decrease in the number of rats?
The snake population will increase.
There will be a decrease in the number of snakes, coyotes, and
hawks.
There will be an increase in the number of coyotes and hawks.
There will be a decrease in the number of cacti and sagebrush
plants.
A student explains that most marine plants are found near the surface of the ocean because the ocean floor does not provide enough minerals for plants.
Which of the following facts is the greatest weakness of the student's explanation?
In the deepest part of the ocean, there is very little light.
Many marine animals are also found near the surface of the
ocean.
Deep-water vents on the ocean floors heat up the nearby water.
Many plants are found on the ocean floor in the shallows close
to shore.
Many plants that live in the desert have leaves in the form of spines.
Why are spines an important adaptation in this desert environment?
They reduce the amount of water lost by the plant.
They conduct photosynthesis faster than a flat leaf.
They provide food for reptiles.
They allow the plant to absorb minerals.
Snails are classified into a much larger group of animals called mollusks, all having a unique file-like tongue called a radula.
Why would it be beneficial for you to have a snail in your aquarium?
Why would it be advantageous for the snail to have a tongue with rows of spiked teeth?
to scrape algae off of hard surfaces
to enable the snail to move more easily in an aquatic environment
to extract extra food from gravel
to efficiently clean the surface of the water
If you eat a sandwich with lettuce and tomatoes,where would you be placed on the food chain?
producer
primary consumer
secondary consumer
tertiary consumer
