Glencoe Biology Chapter 3 Exam

Front

What is the abyssal marine zone?

Back

The abyssal marine zone is a deep-sea environment characterized by low temperatures, high pressure, and low light, typically found at depths of 2000 meters or more.

Front

What is the predicted species diversity in the abyssal marine zone?

Back

Low species diversity is predicted, except around hydrothermal vents where specialized organisms like bacteria, fish, and crabs thrive.

Front

What is a niche in ecology?

Back

A niche refers to the role or function of an organism within its ecosystem, including its habitat, resource use, and interactions with other organisms.

Front

What is primary succession?

Back

Primary succession is the process of ecological change that occurs in an area where no soil exists, such as after a volcanic eruption or glacier retreat.

Front

What is secondary succession?

Back

Secondary succession is the process of ecological change that occurs in an area where a disturbance has destroyed an existing community but left the soil intact.

Front

How does altitude affect climate?

Back

An increase in altitude generally leads to a decrease in temperature and can also result in decreased precipitation.

Front

What is the difference between primary and secondary succession?

Back

Primary succession occurs in lifeless areas without soil, while secondary succession occurs in areas where a disturbance has cleared an ecosystem but left the soil.

Front

What are biotic factors in an ecosystem?

Back

Biotic factors are the living components of an ecosystem, such as plants, animals, and microorganisms, that interact with each other.

Front

What are abiotic factors in an ecosystem?

Back

Abiotic factors are the non-living components of an ecosystem, including temperature, water, soil, and sunlight.

Front

What is the role of starfish in their ecosystem?

Back

Starfish are important predators that help control the population of other species, maintaining the balance of the ecosystem.
