1. What is bioversity? What 4 elements make up 99% of all species?
- Bioversity is when there are several different ogarnism but all have one main thing in common.

2. What is photosynthesis?
- Picture.
- Picture.
3. Describe the flow of energy through systems. What is the main storage molecule of energy in animals?
-Flow of energy through through living system. Main storage molecule is carbohydrate.
4. What is chemosynthesis? What source of energy is used instead if sunlight?
-Chemosynthesis uses chemical for energy instead of sunlight. Hydrogen sulfied.
5. What is primary productivity a measure of?
- A measure of how many plants are there are on the planet.
6. Looking at the map of the productivity around the world- Discuss what you see:
-The most of productivities are on the north.
+Why is productivity higher near the coasts of continents than in the open oceans?
Because of the nutrients from the upwelling.
+Why productivity higher near the the poles?
-Because of all the nutrients brought due to the currents.
Autotrophs: Organisms that make their own food, also called producers.
Heterotrophs: Organisms that must consume other organisms for energy.
Trophic Pyramid: A model that describe who eats whom.
Primary consumers: These organism eat producers.
7. In a food web, what do the arrows represent?
- The arrows show the direction of energy flow.
8. What are some atoms and molecules that cycle in biogeochemical cycles?
- Carbon, nitrogen, phosphorus and silicon, iron and trace metals
9. Diagram the Carbon Cycle in the Ocean:
- The picture will be on the left.
10. Diagram the Nitrogen Cycle in the Ocean:
-The picture will be on the left.
11. Diagram the Phosphorus Cycle in the Ocean:
- The picture will be on the left.
12. What is a limiting factor in ecosystems?
- It's a factor found in the environment that can be harmful if present in quantities that are too large or too small.
13. What are the most important physical factors for marine organisms?
15. Define the following zones:
Euphotic: most of the biological productivity of ocean occurs in the area near the surface, enough sunlight for photosynthesis and vision
Disphotic: not enough sunlight for photosynthesis, vision only
Aphotic: no sunlight
16. Define the following nutrient transports:
Diffusion: mixing due to random molecular movements
Osmosis: diffusion of water through a membrane
Active Transport: transport of substance against a concentration gradient, requires energy input
17. What are the major zones of the ocean?
- The major zones are the Light Zones, Habitat Zones, and the Lifestyle Zones.
18. What is natural selection?
- When the environment favors individuals that are well adapted. Their favorable traits are retained because they contribute to organism's reproductive success.
19. Who was Carolus Linnaeus? What did he do?
- He was one of the first to use the system of natural classification, developed classification system based on hierarchy, and system of scientific names for organisms.
20. What is taxonomy?
- The study of biological classification
21. What are the 6 kingdoms and how are they further divided?
- The six kingdoms are Fungi, Arimalia, Plantae, Protista, Archaea, and Bacteria. They are divided into two different sections as eukaryotes, and prokaryotes.

13. What are the most important physical factors for marine organisms?
- Light
- Dissolved gases
- Temperature
- Acid-base balance
- Salinity
- Hydrostatic pressure
- Dissolved nutrients
- Feeding relationships
- Crowding
- Metabolic waste
- Defense of territory

zones:
Light Zones: The zone when an amount of light reaching through seawater and down to the ocean
floor exerts an enormous influence on the nature and abundance of sea-life.
Habitat Zone: The zone where two primary divisions are the pelagic zone (water zone), and the benthic zone (bottom zone). Different habitat zones offers different challenges and opportunities.
Lifestyle Zone: The zone where plants and animals falls into just four groups.
