Environmental Science Unit 4-7 review

Front

Where is the most newly formed area of any crystal always found?

Back

At the outer edges or tips of the crystal.

Front

What is the term for the variety of processes such as energy flow and matter cycling that occur within ecosystems as species interact with one another in food webs?

Back

Ecosystem diversity.

Front

How does ocean crust compare to continental crust in terms of density and thickness?

Back

Ocean crust is more dense and thinner than continental crust.

Front

What is an example of a negative feedback loop in ecosystems?

Back

Predator populations increasing as prey populations rise, eventually reducing prey numbers.

Front

What does the yellow line in a population growth graph typically represent?

Back

Carrying capacity.

Front

Define ecosystem diversity.

Back

The variety of processes and interactions within ecosystems, including energy flow and matter cycling.

Front

What is the difference between oceanic and continental crust?

Back

Oceanic crust is denser and thinner compared to the less dense and thicker continental crust.

Front

Explain the concept of carrying capacity in an ecosystem.

Back

The maximum population size of a species that an environment can sustain indefinitely.

Front

What role do predators play in maintaining ecosystem balance?

Back

Predators help control prey populations, preventing overpopulation and resource depletion.

Front

What is a positive feedback loop?

Back

A process that amplifies changes; for example, melting ice leading to more sunlight absorption and further ice melting.
