Weather is the day to day conditions of Earth's atmosphere where as climate is the average conditions of Earth's atmosphere over long periods of time.
What is the difference between weather and climate?
|
The range of physical and biological conditions in which a species lives and the way the species obtains what it needs to survive and reproduce.
What is a niche?
|
Primary succession
What is the kind of succession that begins in an area with no remnants of an older community?
|
Trop. rain forest, Trop. dry forest, Trop, grassland, desert, Temp. grassland, Temp. woodland, Temp. forest, NW coniferous forest, Boreal forest/Taiga, Tundra
name three types of biomes.
|
The place at which a river meets the sea. Salt water meets fresh water.
What is an estuary?
|
|
-solar energy trapped in the biosphere (greenhouse effect)
-latitude -transport of heat by winds and ocean currents
What is one factor that causes a difference in climate?
|
When an organism attempts to use the same limited resources in the same place at the same time as other organisms.
What is competition?
|
Pioneer species.
The first species to colonize barren areas.
|
Biomes are described in terms of abiotic factors like climate and soil type, and biotic factors like plant and animal life.
What biotic and abiotic factors characterize biomes?
|
The photic and aphotic zones
In what two ways is the depth of water classified?
|
|
the process in which CO2, methane and water vapor trap sunlight energy in earth's atmosphere as heat.
What is the greenhouse effect?
|
No two species can occupy exactly the same niche in exactly the same habitat at exactly the same time.
What does the competitive exclusion principle state?
|
After disturbances, some species die out and new species move in.
How do communities change over time?
|
canopy and understory
What two layers of trees make up the tropical rain forest?
|
water depth, temperature, flow, and amount of dissolved nutrients
What factors affect life in aquatic ecosystems.
|
|
polar=least
temperate=less tropical=most
What are the three climate zones of the Earth and which regions receive the least direct sunlight, less direct sunlight and the most direct sunlight?
|
PP- Predators capture and feed on prey. Predators can affect the size of prey populations in a community.
HP- An Herbivore feeds on plants. Herbivores affect the size and distribution of plant populations in a community.
Describe the roles of either Predator vs. Prey or Herbivore vs. Plants.
|
a series of more-or-less predictable changes that occur in a community over time
What is ecological succession?
|
Tundra
In what biome would you find permafrost?
|
rivers and streams, lakes and ponds, freshwater wetlands
Name one category of a freshwater ecosystem.
|
|
-Wind is created when warm air rises and expands where it loses heat along the way, sinking as cool air and condensing. The circular motion of air rising and sinking causes wind.
-Ocean currents are caused when winds push against the surface of water.
How does the distribution of heat create winds and ocean currents?
|
Mutualism- a relationship in which both organisms benefit from each other
Commensalism-a relationship in which one organism benefits and the other is neither helped nor harmed Parasitism- a relationship in which one organism lives in or on the other, harm
Give the three main classes of symbiosis and a description of one.
|
Sometimes. In situations where a disturbance affects the community without completely destroying it, healthy ecosystems often reproduces the original climax community.
Do ecosystems return to "normal" following a disturbance?
|
mountain ranges and polar ice caps.
What areas are not easily classified into a major biome?
|
Ecologists typically divide the ocean into zones based on depth and distance from the shore.
How do ecologists usually classify marine ecosystems?
