To distinguish developmental patterns To distinguish developmental patterns found in various animals found in various animals (Metamorphosis)(Metamorphosis)
To compare several symbiotic To compare several symbiotic relationshipsrelationships
SymbiosisSymbiosis
SymbiosisSymbiosis 1. Close relationship between 1. Close relationship between two organismstwo organisms
2. One lives near, on or in the 2. One lives near, on or in the otherother
SymbiosisSymbiosis
CommensalismCommensalism One organism benefits and the One organism benefits and the other is not effectedother is not effected

Barnacles on the backs of crabs are fed Barnacles on the backs of crabs are fed as the crab moves through the water- as the crab moves through the water- but, the crab is left unaffectedbut, the crab is left unaffected

Remora fish attach themselves by suckers to Remora fish attach themselves by suckers to sharks. This allows them to filter in food sharks. This allows them to filter in food while the shark swims- this relationship has while the shark swims- this relationship has no apparent effect on the sharkno apparent effect on the shark

Complete Complete MetamorphosisMetamorphosis
1. Fast, drastic changes in the 1. Fast, drastic changes in the form of an organismform of an organism
2. Appearance looks totally 2. Appearance looks totally different in each stagedifferent in each stage
3. Ex: Butterfly, Ladybug, 3. Ex: Butterfly, Ladybug, FrogFrog
1. Laid under leaves 2. Caterpillar actively eats
3. Cocoon/ Chrysalis protects during development
4. Wings, bright colors sips liquids
1. Yellow rice masses laid on a leaf
2. Long body, 6 legs, actively eats
3. Pupa revealed when larva splits open
4. Mobile (moves a lot)
1. Egg masses laid in water
2. Tadpole/polliwog swims, eats, grows- has gills and tail
3. Tadpole with legs- sprouts arms and legs- has gills and tail
4. Froglet- has lungs, still has tail
5. Adult- no tail, uses lungs
