Aquatic Science Fall Semester Review

Front

What are algae and why are they considered beneficial?

Back

Algae are simple, photosynthetic organisms that grow quickly and can thrive in various environments, including unusable land. They are beneficial as a food crop due to their rapid growth and ability to produce oxygen.

Front

What phase of the water cycle involves the transformation of water vapor into liquid water?

Back

Condensation is the phase of the water cycle where water vapor cools and transforms into liquid water, forming clouds.

Front

Identify the cycle that involves the movement of phosphorus through the environment.

Back

The Phosphorus cycle is the process by which phosphorus moves through the lithosphere, hydrosphere, and biosphere.

Front

What instrument is used to measure the temperature of water in an aquarium?

Back

A thermometer is used to measure the temperature of the aquarium water.

Front

What is the primary function of a water heater in an aquarium?

Back

A water heater is used to heat water to maintain a suitable temperature for aquatic life.

Front

Define the water cycle.

Back

The water cycle is the continuous process by which water evaporates from the Earth's surface, condenses in the atmosphere, and returns as precipitation.

Front

What is transpiration in the context of the water cycle?

Back

Transpiration is the process by which water is absorbed by plant roots, moves through plants, and is released as vapor through pores in leaves.

Front

Explain the role of runoff in the water cycle.

Back

Runoff is the flow of water, from rain or melting snow, over the land surface, which eventually returns to bodies of water.

Front

What is the significance of the carbon cycle?

Back

The carbon cycle is crucial for regulating Earth's climate and supporting life by cycling carbon through the atmosphere, oceans, soil, and living organisms.

Front

Describe the nitrogen cycle.

Back

The nitrogen cycle is the process by which nitrogen is converted between its various chemical forms, including fixation, nitrification, and denitrification, essential for plant growth.
