Vocabulary 1
the ways in which organisms interact with each other
symbiosis
the first species in an otherwise lifeless area
pioneer species
relatively mild summers and cold winters; trees here lose their leaves; rich topsoil over clay - we live in this biome
deciduous forest
The three types of symbiosis are...
a. pioneer species are always plants
b. climax communities stay largely unchanged unless a major event occurs
c. a climax community usually takes a year to develop
d. a pioneer community is the same thing as a climax community
b. climax communities stay largely unchanged unless a major event occurs
a sandy, rocky biome with little precipitation and little plant life
desert
when one organism benefits from another while harming or weakening the other
parasitism
very cold winters, cool summers; about 20 in. of precipitation per year; snowshoe hares, lynx, sables live here
taiga
the relationship between the yucca moth and the yucca plant
mutualism
Which statement is false?
a. each biome has a unique climate
b. all biomes have the same kind of soil
c. the rain forest has a greater number of plant and animal species than the tundra
d. desert biomes can be found all over the world
b. all biomes have the same kind of soil
a forest biome with trees that lose their leaves each year
deciduous forest
large, treeless plain in the arctic region where the ground is frozen most, if not all, of the year
tundra
more species of plants and animals live in this biome than in any other
the relationship between clown fish and sea anenomes
commensalism
succession
characteristics that help an organism survive in its environment
adaptations
tropical rain forest
mostly grasses and small shrubs; lands is mostly flat with rich topsoil; few trees near sources of water
grassland
The orchid plant trails up the trunk of a tree to gain more access to sunlight. This is an example of:
commensalism
Name at least one factor that determines where organisms live within the regions of the oceans.
answers may include:
sunlight
access to the surface for breathing
temperature
the final stage of ecological succession
climax community
anything that controls the growth or survival of a population
limiting factor
only about 4-10 inches of precipitation fall in this biome per year
Tundra
The relationship between the coiling dodder plant and any stem it grows on - the coiling dodder plant can't make it's own nutrients. It inserts a tube into the stem it's coiled around to obtain nutrients from its host.
Answers may include:
climate
amount of precipitation per year
