____ also called biotic change, is the natural change of one type of vegetation to another.
Primary succession is ....
the process of succession of land with no developed soil
Secondary succession occurs ....
What are some disturbances that might lead to secondary succession
Disturbances leading to secondary succession include forest fires, flooding, and human interaction
What is a pioneer species
The following is a description of succession common for much of North Carolina: the first plants
to begin growing are called the pioneer species, which are the weeds and grasses. These are
followed by shrubs, then pine forest, and finally hardwoods. Name the plants that grow in chronological order.
Pioneer species (weeds and grasses), shrubs, pine forest, hardwoods
The final community of natural vegetation that does not change unless disturbed.
(a)
What is the typical climax community in NC
Oak-Hickory Forest
All stages of succession provide habitats for different species
Habitats with greater variety in vegetation appeal to more species
Even though the greater the variety in vegetation come species still need the forest interior (either pine or deciduous forests)
Without old field succession, habitat for some species would be limited
Ponds and lakes also go through succession. Is the time period longer or shorter than land succession
As sediment is carried into the pond, the bottom begins to fill in, and the water becomes
shallower. The pond then can become a marsh, wet meadow, grassland, and finally a forest.
As with the succession of a bare field, each habitat created in each of the steps of pond
succession provides for the needs of diverse species of plants and animals.
As vegetation types increase and a larger variety of species can live there an environment become more complex. Is a meadow or a deciduous forest more complex?
Meadow
Both are equally complex
The above statement is false, variety of wildlife does not increase how complex the environment is
Define Species Diversity, also called Biodiversity
Species diversity is the number of different types of organisms
Define genetic diversity
Genetic diversity is the diversity of genes in a population
Define ecosystem diversity
Ecosystem diversity is the diversity of all habitats, communities, and processes in an ecosystem
The area between two different
types of habitats, such as
between a forest and a field, will
have vegetation from both
habitats. These transitional
zones, where two or more
communities meet and
combine, are called (a)
or edges.
Ecotones or Edges contain all or most of the niches found in both ecosystems, but do they also contain new niches found only in the edge
The change in variety of species in the transition area, or ecotones, is called the ...
(a)
Some species require large expanses of the same type of habitat. These are called _____ and they do not benefit from edges
What are some examples of interior species
Wood Thrush, Oven Bird, and various species of warblers
