,When two species C.a move from the fundamental niche to the realized
compete for similar niche for both species.
resources, resource
partitioning can alter the
niche of the species that
compete. The figure shows
an example of this.
Resource partitioning
results in:
A. individuals of each
species sharing the
resources that they both
exploit.
B.individuals of each
species hybridizing in the
region of overlap.
C.a move from the
fundamental niche to the
realized niche for both
species.
D.a move from the
realized niche to the
fundamental niche for
both species.
Phylum chartacterized by radial symmetry, 2 germ
tissues in the embryo; a closed internal gastric cavity,
Cnidaria
and well-developed tissues but not organs; includes
jellyfish, esea anemones, and corals
Monophyletic group of animals with bilateral
Bilateria
symmetry
Bilaterian in whcih the blastopore first opening to
Protostomes
internal cavity of developing embryo becomes mouth
, Bilaterian in which the blastopore, the first opening to
the internal cavity of the developing embryo,
Deuterostomes
becomes the anus
Humans and chordates
Type of cell that lines the interior surface of a
Choanocytes sponge;have flagella and function in nutrition and gas
exchange
Gelatinous mass lies between interior and exterior cell
layers of sponge that contains some amoeba-like
Mesohyl
cells that function in skeleton formation and dispersal
of nutrients
Eumetazoa Monophyletic group of all animals other than sponges
Cindarians, closed internal site where extracellular
Gastric Cavity
digestion and excretion take place
Mammals, outer layer of skin, which serves as a water-
resistant, protective barrier.
Epidermis Plants, outermost layer of cells in leaves, young stems
(lacking secondary growth), and roots. Outer layer of
cnidarian body.
In plants, layer of cells surrounding the xylem and
phloem at the center of the root that controls
Endodermis
movement of nutrients into xylem
Inner lining of cnidarian body
In cnidareans, gelatinous mass enclosed by epidermis
Mesoglea
and endodermis
Possibly simplest of all animals; each contains only
few thousand cells arranged into upper and lower
Placozoans
epithelia that sandwwich an interior fluid crisscrossed
by network of multinucleate fiber cells

Annelid Worms
segments and a bilaterian body plan
