In a food chain, energy does not flow directly from –
producer to consumer
consumer to producer
consumer to decomposer
producer to decomposer
In a desert food chain, wild pigs eat cacti. Then, coyotes eat wild pigs. When the coyote dies, its body begins to decay and the nutrients are returned to the soil. How does energy move in this food chain?
from producers to consumers to decomposers
from consumers to producers to decomposers
from decomposers to consumers to producers
from decomposers to producers to carnivores

white tailed deer
Mushroom
Black bear
Maple Tree
The table below shows some of the common animals found in a coral reef ecosystem. Based on the information in the table, which two types of animals are competitors for food?
Black-Tipped Reef Shark and Sea Stars
Sea Stars and Clownfish

Plants grow from seeds. Sometimes the seeds are carried far away from the parent plant. Both of these seeds have structures that –
allow them to be dispersed by sunlight
allow them to be dispersed by wind
allow them to be dispersed by water
allow them to be dispersed by animals
The owl butterfly and swallowtail caterpillar have patterns on their body that look like large eyes. How does this adaptation help them survive?
It helps them to move around at night.
It helps them absorb sunlight.
It helps them scare away predators.
It helps them see farther than other insects.
All of the following are inherited traits found in plants except –
the color of a plant’s flower
the number of insects that pollinate it
the type of root structure
the shape of a plant’s leaves
A wetland was drained to build a mall. Two years later, there were no more toads in that area. Why did the toads disappear?

The toads were destroyed by the construction equipment.

What is the most likely explanation for the formation of the valley pictured below?
Erosion by water
Deposition by wind
Erosion by a glacier
Weathering by wind
Explain how the stalagmites in a cave are formed.
Wind deposits dust and rocks into caves which build up over time.
Water drips slowly to the cave floor and deposits minerals as it evaporates.
Moving water erodes shapes as it washes through the cave.
Ice forms overnight and cracks the rocks into shapes before it melts away.
The diagram below shows the sequence of the processes that turn solid rock into sandstone. Which two processes best complete this diagram?
Weathering and eroding
Compacting and cementing
Eroding and compacting
Dissolving and cementing
Which is the best explanation for how fossil fuels form?
Dead organisms are buried beneath sediment and exposed to heat and pressure over millions of years.
Dinosaurs are buried in hot tar, adding their bodies to the mass of fossil fuel.
Plants die in swamps and their bodies change into fossil fuels.
Ocean water turns dead plants and animals into fossil fuels

Only animals that eat other animals lived in the area.
At one time, the area where this rock was formed was covered by water.
Some processes that change landforms are constructive and some are destructive. Which of the following is an example of a constructive process shaping a landform
Wind weathers rock into sand.
Earthquakes move land and rocks.
Rivers carry sediment and build deltas.
