Ecology

Question 0

Organismal ecology

Answer 0

Focused in integration between individual and environment. Considers morphology, physiology and behavior.

Question 1

Ecology

Answer 1

The study of how organisms interact with the environment

Question 2

Population ecology

Answer 2

The central goal is to understand mechanisms relating to population growth. Also looks at interactions between members of a population.

Question 3

Community ecology

Answer 3

The focus is on inter specific interaction, community structure, and community’s response to disturbances in the environment.

Question 4

Ecosystem ecology

Answer 4

Focuses on nutrient cycles and energy flow. Expands to include both biotic and abiotic interactions.

Question 5

Climate

Answer 5

Long term atmospheric or aquatic conditions.

Question 6

Whether

Answer 6

Short term atmospheric or aquatic conditions.

Question 7

Hadley cell

Answer 7

The Hadly cells lie at the equator and extend to plus or minus 30 degrees of latitude. Convection currents. Air warms at the equator and becomes full of water. Warm air can hold more water than cold air. The rising air cools causing precipitation. When the cool air later sinks it heats up when it gets to the ground and sucks moisture out of the the ground and air and goes back to the equator.

Question 8

Ferrell cells

Answer 8

North and south of the Hadly cells. Air sinks at plus or minus 30 and rises around plus of minus 60.

Question 9

Polar cells

Answer 9

Air rises at 60° and sinks at 90° these polar cells work in the same way as the Hadley cells and Ferrell.

Question 10

Seasonality

Answer 10

Seasonality is caused by the Earth’s 23° tilt. This results in boreal and austral summers. Boreal being North, austral being south. Seasons are more pronounced with latitude

Question 11

Wet side

Answer 11

The side of the mountain facing the water is known as the wet side. This causes air to rise, cool, and release moisture.

Question 12

Dry side

Answer 12

Also known as the rain shadow. Cold dry air falls and is warmed up. The air absorbs moisture.

Question 13

Ocean weather

Answer 13

The temperature fluctuations are less, due to the fact that water has very high specific heat which results in cooler summers and warmer winters–so more constant.

Question 14

key abiotic factors that regulate ecosystems

Answer 14

Temperature precipitation

Question 15

Key abiotic factors regulating aquatic ecosystems

Answer 15

Sunlight and nutrients

Question 16

Key abiotic Factors regulating terrestrial ecosystems

Answer 16

Soil retain its nutrients. Large regions are characterized by distinct vegetation types. Each has distinctive temperature and precipitation regimes.

Question 17

Lentic systems

Answer 17

Still or slowly flowing water. This includes lakes and ponds , as well as swamps, marshes, and bogs.

Question 18

Lotic Systems

Answer 18

Rapidly flowing water. Streams.

Question 19

Littoral zone

Answer 19

Sallow enough for rooted vegetation.

Question 20

Limnetic zone.

Answer 20

This zone is too deep for rooted vegetation.

Question 21

Difference between swamps and marshes

Answer 21

Swamps have trees, but they both have slowly flowing water an typically the on net to lakes or streams.

Question 22

Bogs

Answer 22

Stagnant and highly acidic fur to deck positions.

Question 23

Lotic Systems

Answer 23

Round unidirectional water flow. A river is a big stream a creek is a small stream.

Question 24

Linear progression of streams

Answer 24

Early: low temperature and nutrients, high oxygen. Middle: a bit more nutrients and slightly higher temperature and lower oxygen. Late: warmest, most nutrients, lowest oxygen.

Question 25

Estuaries

Answer 25

Formed when rivers meet oceans. There is a mixture of fresh water and salt water. Very productive to life.

Question 26

Marine ecosystems

Answer 26

There are three horizontal zones: intertidal, neuritic, and oceanic; and two vertical zones: photic and aphotic.

Question 27

Intertidal zone

Answer 27

This zone is converted and uncovered by tides.

Question 28

Neritic zone

Answer 28

The portion of the ocean over the continental shelf.

Question 29

Oceanic zone

Answer 29

Portion off continental shelf.
