Nine Major Animal Phyla

1. List all nine major animal phyla, and an example image of animal in the phyla.

    1. Porifera - The Sponges

    2. Coelenterata – The Coelenterates

    3. Platyhelminthes – The Flatworms

    4. Nematoda – The Roundworms

    5. Annelida – The Segmented Worms

    6. Arthropoda – The Arthropods

    7. Mollusca – The Mollusks

    8. Echinodermata – The Echinoderms

    9. Chordata – The Chordates

2. What type(s) of habitat can the species be found?

-Manly in Marine or fresh and Salt Water

3. How does the species digest food?

-Some species have a complete digestive system and others incomplete

4. Have you seen an example of a species in a phyla? Explain where, and what was the situation.

- An example I have is when i went to Sea World, and i saw an aquarium full of sting rays and we got to touch them.

Big Question: Why should we humans be concerned about overfishing?
 - Poor Fisheries Management
 - Pirate Fishers(don't respect fishing laws or agreements)
 -Subsidies that keep too many boats on the water

1. What are the "Big Five" fish we eat all the times?
 - Alaska or Walleye Pollack
 - Anchovy
 - Arctic Char
 - Beam, Gilthead
 - Brill

2. What is a reason for not eating sharks or other deep water fish?
 - They tend to be slow growing, long-lived species such as red fish and orange roughly, which breed slowly and are vulnerable to over exploitation

3. What are some "fish to eat," "fish to eat occasionally," and "fish to avoid"?
 - Fish to eat: well managed , sustainable stocks of farms, or are resilient to fishing pressure
 - Fish to eat occasionally: from fisheries that are at risk of becoming unsustainable due to environmental, management or stock issues
 - Fish to avoid: from  unsustainable, overfished, highly vulnerable or poorly- managed fisheries or farming systems

Big Question: What happens to an ecosystem when a species goes extinct?

- It will really affect the ecosystem

1. What is the most voracious predator the ocean has ever seen?

 - Humans

2. Are the oceans renewable? Why?

 - No because it wouldn't be the same; what people are doing to the ocean

3. When did the cod become fished out, how many people lost their jobs?

 - 1992; 40,000 lost their jobs

4. What puzzled scientists in 2001, where was the answer found, and what was the answer?

 - The total catch was going up; In China; China was getting all of the fishes.

Energy Flows Through Ecosystems [ Part 2 ]

1. How does light and nutrients affect productivity in the oceans?

 - Light penetrates only into the uppermost level of the oceans. In high near coastlines and other areas where upwelling brings nutrients to surface, promoting plankton blooms.

2. What factors affect the ability of an ecosystem to support multiple trophic levels?

 - The amount of energy entering the ecosystem, energy loss between trophic levels, and the form, structure, and physiology of organism at each level.

3. Describe the process bioaccumulation, and describe the DDT example.

 - Bioaccumulation is the loss of energy between tropic levels is that contaminants collect in animal tissue.

- DDT built up in eagle and other raptors to levels high enough to affect their reproduction, causing the birds to lay thin- shelled eggs that broke in their nests.

Energy Flows Through Ecosystems

1.) a. Examples of Primary Producers are, and b. how do they get their Energy?

 - Producers: use solar energy to produce organic plant material through photosynthesis.

2.) a. the second trophic level is made up of water creatures and b. from where do they get their energy?

 - Herbivores: They eat only plants.

3.) why do predators make up the third trophic level?

 - It's because they feed at several trophic levels , like for example bears eat berries, honey, salmon, etc.

Animal Habitat Structure

1. How does eelgrass density influence abundance of species in an ecosystem?

My hypothesis: The more dense the eelgrass, the more biodiverse the ecosystem because of the more availability for shelter and food.

Animal Habits of San Diego Bay

1. San Diego Bay is home to a list.of Natural Resources. what are they

- Salt marsh tidal Flats, fish habitats.

2. What is an Invasive Species & How would they have been introduced in SD bay ?

- invasive species are Non native species introduced by fore gin ships.

3. What is an Endangered species? What is being done to protect the species.

- species on the brink of extinction green sea turtles San Diego Bay provides protected foraging habitat.
