BIO-205 Final Review Game 1

Front

What is a nerve net?

Back

A decentralized network of interconnected nerve cells found in certain organisms, such as cnidarians, allowing for basic responses to stimuli.

Front

Which organism has a nerve net?

Back

Sea anemone.

Front

Why do algae have multiple pigments?

Back

To increase photosynthesis by capturing a broader spectrum of light.

Front

What is the primary technology used for deep-sea exploration?

Back

Remote Operated Vehicles (ROVs).

Front

What does the principle of constant proportions state?

Back

The ratio of major salts in samples of seawater from various places is constant.

Front

How much energy is typically transferred from fish to birds in a food chain?

Back

10%.

Front

What is the role of pigments in photosynthesis?

Back

Pigments absorb light energy, which is then used to convert carbon dioxide and water into glucose and oxygen.

Front

Define salinity in the context of ocean water.

Back

The concentration of dissolved salts in seawater, usually expressed in parts per thousand (ppt).

Front

What is the significance of Remote Operated Vehicles (ROVs) in marine biology?

Back

ROVs allow scientists to explore and study deep-sea environments without human divers, providing valuable data and images.

Front

Explain the concept of energy transfer in an ecosystem.

Back

Energy transfer refers to the flow of energy from one trophic level to another, typically decreasing by about 90% at each level.
