Modified 6th Grade Interim Assessment 3 Review

The picture shows a bear entering a state of sleep called torpor. Bears use torpor to survive the winter months. Bears in torpor can sleep more than 100 days without eating or drinking.

What factors cause a bear to enter a torpor sleep?

• It is too rainy.

• It is too cold.

• It is too dark.

What factor could cause a plant to become dormant?

• There is not enough water.

• It is going to make a flower.

• Bees are pollinating the plant.

When it is very dry in the African Savannah, large herds of zebras and other animals move together as a group to find a source of water. What factor causes that migration?

• All animals must have water to live.

• Migrating animals look for rain.

• The animals need to find fish to eat.

During the fall, bears will eat extra food and chipmunks will find seeds to store for eating later. Why are these animals most likely eating and storing extra food?

• These animals are preparing to hibernate during the cold winter.

• These animals are preparing to migrate and will need the food for the journey.

• These animals are preparing to survive a flood, and all their food will be washed away.

A student was reading about monarch butterflies.

Why do monarch butterflies migrate South?

• To find warmer temperatures

• To find other monarch butterflies

• To find materials to build nests

Flowers depend on sunlight to make their own food. Butterflies eat nectar from the flowers. Toads eat butterflies.

How can the flow of energy in the environment be described?

• Toads provide energy to butterflies.

• Nectar provides energy to flowers.

• Flowers provide energy to butterflies.

• Flowers provide energy to the Sun.

What is one example of the way that energy flows in the food chain above?

• Energy flows from grass to the Sun

• Energy flows from hawks to snakes

• Energy flows from grasshoppers to finches

• Energy flows from snakes to finches

Students decided to build their own terrarium so they can study how the physical characteristics of an environment support a community. The terrarium has plants, grass, crickets, water, and a lizard.

Which organism in the terrarium shown above starts the flow of energy through the food chain?

• Cricket

• Water

• Grass

• Lizard

The picture shows an ecosystem.

What will most likely happen if bees are removed from the ecosystem?

• Flowers could be pollinated but would produce smaller seeds, making less food for plant-eater

• Some flowers would not be pollinated, fewer seeds would be produced, and there would be less food for plant-eaters.

• Flowers could be pollinated and would produce more seeds, making more food for plant-eaters.

• Flowers would not be pollinated, more seeds would be produced, and there would be more food for plant-eaters.

There has been reduced rainfall in the area. A drought occurs at the pond.

What is the most likely way the drought will affect the animals in the above ecosystem?

• The frogs will move.

• The squirrels will die.

• The dragonflies will thrive.

• The fish will die.
