Food Webs• What do the
arrow mean?• What are the
producers?• Primary
consumers?• Secondary
consumers?• Tertiary
consumers?

Try this one!: producer, each level of consumers are?????

Now put into a food pyramid

Can you think of adaptations that animals we discussed have had?
• Cephalopods: what is an example of a cephalopod?– Modified mantle to swim in open water– Beak from radula to crush prey– Males modified organ to deposit sperm so females
don’t eat them• Fish: – body shapes adapted for habitat– Coloration for mates, defense or camouflage

Day 2 Review: Osmosis and Diffusion
• What is osmosis and diffusion?• Hypertonic solution?• Isotonic solution?• Hypotonic solution?• What happens to an animal cell when placed
in these solutions?

Plate Tectonics• What are the type of boundaries and ecosystems
related to each?– Convergent (subduction)• What ecosystems do you find here?• What adaptations for animals?
– Divergent• What newly discovered ecosystems here• What adaptations for animals?
– Hot Spots• What ecosystems are formed?
![Page 14: Marine review final](https://reader033.vdocument.in/reader033/viewer/2022061213/5498445aac7959292e8b5584/html5/thumbnails/14.jpg)
Reproduction• Asexual- What process is this type?
• what is the advantage?• What is the disadvantage?• When would this be the better method of
reproduction?• What types of organisms reproduce this way?• Types of a asexual: budding: offspring grows out of
parent, fragmentation: part of parent breaks off that can reproduce
![Page 15: Marine review final](https://reader033.vdocument.in/reader033/viewer/2022061213/5498445aac7959292e8b5584/html5/thumbnails/15.jpg)
Reproduction• Sexual – what process is this type?
• what is the advantage?• What is the disadvantage?• When would this be the better method of
reproduction?• Types external and internal fertilization.
– Which has higher survival rate? – What organisms reproduce these ways?

Taxonomy
• How do you classify species into groups?• How can you find the scientific name of a
species unknown to you?
![Page 17: Marine review final](https://reader033.vdocument.in/reader033/viewer/2022061213/5498445aac7959292e8b5584/html5/thumbnails/17.jpg)
Population Density
• What data do you collect in the field?• What organisms are best to sample this way?• What can this data tell you about other
organisms living in this ecosystem?
![Page 18: Marine review final](https://reader033.vdocument.in/reader033/viewer/2022061213/5498445aac7959292e8b5584/html5/thumbnails/18.jpg)
How are organisms affected by these in an ecosystem
• Abiotic Factors• Temp• Salinity• Turbidity• Pressure• Amount of sunlight• Pollutants • Weather conditions
• Biotic Factors• Other organisms• Plants• animals
