Ecology

Which of these levels includes the other: population and ecosystem.

Ecosystem includes the population.

Levels of ecology from largest to smallest.

Biosphere, Ecosystem, Community, Population, Organism

An example of biotic factors.

Animals

An example of abiotic factors.

Energy, nutrients, wind, temperature, water

The most limiting abiotic factor on land?

Water

Organisms cannot survive at temperatures above 45C because?

Enzymes would be destroyed

Three types of organismal responses to environmental variability.

Physiological, Anatomical, Behaviorial

Earth surface is split up into a series of "-", which are specifiv zones with a particular biological community determined by enviro & vegit

Biomes

Aquatic Biomes

Freshwater, Intermediate, Marine

Aphotic Zones

don't receive sunlight

Hold and filter large amounts of water

wetlands

Interidal Zone

Where the ocean meets the land

Esutuaries

where a river or stream merges with ocean

Three processes that affect water cycle

Evaporation, Condensation, Precipitation

4 Levels of Ecology

C.O.P.E.: Community, Organismal ecology, Population, Ecosystem

Acclimation

A gradual, though still reversible physiological adjustment that occurs in response to an environmental change. Ex: contracting skin muscles

Endothermic vs. Ectothermic

Endothermic: birds and mammals can tolerate the greatest temperature extremes because they are endotherms Ectothermic: reptiles can only tol

Anatomical Response

some type of change in body shapes/structure occurs in response to environmental challenge. Ex: mammals grow a heavier coat of fur before we

Behavioral Responses

Most animals can respond to an unfavorable change in the environment by moving to a new location

Photic Zone

light is available for photosynthesis, includes the shallow water near shore and the upper layer of water away from shore.

wetland

transitional biome between an aquatic and terrestrial ecosystem.

benefits of wetlands

natural barrier, flood prevention, biodiversity, purify water

Photographs taken with microscopes.
