Aquatic Science Chapter 11

The high winds of hurricanes often destroy seagrasses. The destruction of these plants most likely affects ecosystems by_

• Reducing beach erosion in sea-turtle nesting areas

• Reducing the amount of saltwater flowing into lakes.

• Forcing aquatic organisms to find other places for nurseries

• Causing pollution in inland rivers and streams.

How does freshwater inflow affect bays and estuaries?

• Provides freshwater for plants.

• Provides for many niches in an estuary ecosystem.

• Provides nutrients to feed fish, wildlife, and invertebrates.

• B and C.

Tides are:

• Variable, but predictable

• Heights and timings vary daily.

• Produced by the gravitational attraction of the Moon, Sun, and Earth on our oceans.

• All of the above.

Seawater 35 ppt Bay 1 19 ppt Bay 2 38 ppt Bay 3 15 ppt

Based on the data of the biologist, which bay is hypersaline?

• Bay 1

• Bay 2

• Bay 3

• None of the above

Seagrasses:

• Are related to algae

• Have strong supportive stems.

• Provide nurseries for young organisms and reduce erosion.

• Are not affected by extreme currents.

Submerged rooted aquatic plants that can tolerate salt.

• Hypersaline

• Barrier Island

• Ecosystem Services

• Sea Grasses

Long, narrow islands of sand that run parallel to the mainland.

• Ecosystem Services

• Hypersaline

• Sea Grasses

• Barrier Island

A body of water separated by the ocean by a coral reef, sandbar, or barrier island.

• Bay

• Dredging

• Lagoon

• Deltas

The rise and fall of sea level produced by the gravitational pull of the Earth, Moon, and Sun on the Ocean.

• Estuary

• Lagoon

• Deltas
