Multiple Choice

Multiple Choice

Look at the food web of a pond ecosystem.

Which food chain shows the correct flow of energy in the pond 

of the food web?

Multiple Choice

In 2011, fires in Bastrop County, Texas, were the most destructive 

wildfires in Texas history.  

The fire spread through the Loblolly pine trees and scorched 

nearly 5,700 acresof Bastrop State Park.  

The majority of the Houston Toad’s habitat was lost, and 

the Lost Pines Forest was heavily affected.  

A food web of the Bastrop State Park environment is shown below.

The loss of habitat for the Houston Toad most likely affected 

the food web by -

• causing a decrease in the number 

  of wildflowers

• causing an increase in the number 

  of insects

• causing a decrease in the number 

  of armadillos

• causing an increase in the number 

  of opossums

Multiple Choice

These two species of birds, the egret and heron, eat the same types 

of fish as their maindiet. They live in the same ecosystem. 

How would the egrets in this area MOST LIKELY respond if all of the herons were removed from the area?

• They would move to different ponds.

• They would change to another diet.

• They would build fewer nests.

• They would have an increase in population.

Multiple Choice

What would happen to the blue whale population if the krill population went extinct?

• the blue whale population eats other things in the food web

• the blue whale population would increase

• The blue whale population would remain the same.

• the blue whale population would also decrease

Multiple Choice

Which of these is true about this food web?

• The Owl gets its energy from the producer.
• The Lion gets its energy only from a wild cat.
• The Kite gets its energy from the goat.
• The Mouse is most likely to die, several ways.

Multiple Choice

What is the role of decomposers in a food chain?

• Use sunlight to make food
• Eat other organisms to gain energy
• Make the food for the whole food chain
• Break down dead organisms and add nutrients to the soil

Multiple Choice

Recently, a family of bobcats moved into an area with a large rabbit population. What changes may occur in the ecosystem?

• The rabbit population may increase
• The rabbit population may decrease
• The rabbit population may increase first, then decrease
• The rabbit population will remain the same
