Succession
Define community.
a group of interacting populations that occupy the same area at the same time
Define weather.
Areas that are dominated by shrubs are called _________________.
Chaparrals
Provide two examples of animals that would live in a tropical savanna.
Zebras, Lions, Cheetahs, Ostridges
Aquatic biomes consist of two main types of water. Define the two different types.
Salt Water
Freshwater
What is a limiting factor?
any biotic or abiotic factor that restricts the numbers,reproduction, or distribution of organisms
How is climate and weather different?
Climate deals with weather over a long period of time within a biome, whereas weather describes the temperature and precipitation in a given instance (i.e. specific day)
TRUE FALSE Open woodlands and mixed shrub communities are found in areas with less annual rainfall than in temperate forests.
TRUE
What biome is characterized by warm temperatures and large amounts of rainfall throughout the year?
Tropical Rainforest
What are two examples of freshwater ecosystems?
Ponds, Lakes, Streams, Rivers, and Wetlands
TRUE FALSE Factors that restrict the growth of one population might enable another to thrive.
TRUE
TRUE FALSE Latitude is the distance of any point on the surface of Earth west or east from the equator.
FALSE - north or south
Provide two characteristics for a temperate grassland biome.
fertile soils that support a thick covering of grasses, experiences drought, home to a variety of grazing animals, also known as prairies, pampas, savannas, range lands, and steppes
TRUE FALSE The tropical rainforest is not the most divers biome.
FALSE - Tropical rainforest is the most diverse with the greatest biodiversity.
What percentage of water on Earth is freshwater?
2.5%
What are the two main types of succession? Define each, as well as, provide an example for each.
Primary- the establishment of a community in an area of exposed rock that does not have any topsoil
Ex. volcano erupts and lava hardens to create barren land --> lichen, moss, bacteria inhabit the land
Secondary - the orderly and predictable change that takes place after a community of organisms has been removed but the soil has remained intact
Ex. abandoned farm being replaced with housing/businesses
What four major characteristics help to define a terrestrial biome?
Plants
Temperature
Precipitation
Animals
Deserts exist on every continent except......
Europe
What two areas are not classified as a biome? Why?
Mountains and Polar Regions
Mountains are found all over the world and polar regions are made of ice not soil.
What is a transitional aquatic ecosystem? Provide the two examples that were discussed in class.
Estuary (Salt Water + Freshwater)
What is the goal of succession? How long does it take to achieve this goal?
Provide two defining characteristics for each of the following biomes:
Tundra
Temperate Forest
Tundra - cold year round with little precipitation, permafrost layer
Temperate Forest - contains deciduous trees, experiences all four-seasons, biome in PA
Desert Fact: Any area in which the annual _________ ____ __________________ exceeds the ______ ____ __________________.
Any area in which the annual rate of evaporation exceeds the rate of precipitation.
Trees of tropical rainforests grow close to the ____________, while mosses/lichens of tundras grow close to the ____________.
Equator; Poles
What four main zones make up the ocean? List the zones in order from shallow to deepest.
Photic, Aphotic, Benthic, and Abyssal
