Interactions in the Environment Test Module 3

What is matter cycling?

• Movement of matter from one form to another
• Creation of new matter
• Matter moving from Earth to outer space
• Matter cycling only within biotic creatures

How does water travel in the water cycle?

• It follows a cycle of evaporation, condensation, and precipitation.
• It moves in a straight line from the ocean to land.
• It flows only through rivers and streams.
• It remains stagnant in one location.

Where is most of Earth's carbon stored?

• In fossil fuels
• In the atmosphere
• In living organisms
• In the oceans

What is the role of decomposing bacteria in the nitrogen cycle?

• They release nitrogen into the atmosphere.
• They add nitrogen compounds to soil.
• They help plants grow through photosynthesis.
• They convert nitrogen into carbon dioxide.

What is ecological succession?

• A series of changes in an ecosystem over time
• A sudden change in an ecosystem's climate
• The introduction of new species to an ecosystem
• The complete destruction of an ecosystem

Which type of succession occurs when new land is formed or bare rock is exposed?

• Primary succession
• Tertiary succession
• Secondary succession
• Quaternary succession

When does secondary succession occur?

• When a previously occupied area experiences a disturbance
• When new land is formed
• When an ecosystem is created from scratch
• When a stable ecosystem undergoes minor changes

What does the term "carrying capacity" refer to in an environment?

• The maximum population it can support based on the food, water, and resources available.
• The total area of the environment.
• The number of predators in the environment.
• The overall biodiversity of the environment.

What are some of the essential factors that biotic factors require to grow and thrive in an environment?

• Shelter and space
• Temperature and humidity
• Rocks and minerals
• Sunlight and wind

How does a population typically grow in an environment?

• It begins slowly, then enters a rapid growth phase, and finally levels off.
• It grows steadily over time.
• It enters a rapid growth phase immediately.
• It grows exponentially with no limits.
