Environmental changes

A large amount of dust and ash from a recent volcanic eruption settles in the region. Which of the following organisms that live near the volcano will most likely survive? 

• Deer
• Grasses
• Trees
• Fish

An organism that cannot adapt to changes in the environment will most likely - 

• produce more offspring
• die
• change its traits to survive
• store more food

All of the following are examples of environmental changes that can be caused by humans except - 

• clearing land for housing developments
• pesticides
• volcanic eruption
• pollution

Scientists gathered the following data on lizard populations for several years. The results are shown in the table. Which environmental factor most likely contributes to the change in lizard population? 

• increase in available water and food
• increase in shelter
• increase in predators
• increase in light

When a population thrives, it means that-

• the number of organisms is decreasing.

• it is growing strong and reproducing.

• the number of organisms is increasing.

• the number of organisms stays the same.

A fire destroys all of the trees and plants in the forest. How might this affect the birds in the area?

• The birds will plant seeds and grow new trees.

• The birds will have more food to eat.

• The birds will plant seeds and grow new trees.

• The birds will have no place to build their homes.

Changes to an environment may make it more difficult for an organism to find-

• food.

• shelter.

• water.

• all of the above

When an environment changes and organisms can no

longer meet their basic needs they will most likely −

• thrive.

• perish.

• not be affected.

• none of the above

A healthy environment, with no sudden changes will help

organisms to −

• die out.

• perish.

• move to new locations.

• thrive.

Very little rainfall, hot weather, and cracked ground

describe which change to an environment?

• volcanic erruption

• landslide

• drought

• flood
