Autotrophs capture the light energy from
sunlight and convert it to chemical energy
they use for food.
Heterotrophs must get energy by eating
autotrophs or other heterotrophs.
 Decomposers (aka saprobes) are
heterotrophs that recycle dead organisms by
breaking them down. Fungi are decomposers.
~ Body Plans of Animals~
• An animal shows asymmetry if there is
no central axis (some sponges)
• An animal has radial symmetry if it can
be divided along any plane, through a
central axis, into equal halves. (jellyfish,
sea anemone)
• An animal has bilateral symmetry if it
can be divided down its length into similar
right and left halves forming mirror
images of each other. (eel, bird, fox)
Which figure has bilateral symmetry?
Which has radial symmetry?
Anatomical Terms for Animals
Reproduction
Asexual reproduction – No separate male
and female parts
binary fission – division of one cell or
body part into two (flatworms)
budding – an outgrowth from the
original organism (hydra)
Sexual reproduction – has male and female
parts, union of two separate gametes.
