Exploring ocean zones
Chapter #13: PPT- Guided Viewing Notes
1: What is biodiversity? What 4 elements make up 99% of all species?
Different species. hydrogen, carbon, oxygen, nitrogen
2: What is photosynthesis?
the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water
Label the diagram of photosynthesis:
3: Describe the flow of energy through systems. What is the main storage molecule of energy
in animals?
at each step, energy is degraded ( that is, transformed into a less useful form). light energy, chemical energy, energy of movement, waste heat, entropy
4: What is chemosynthesis? What source of energy is used instead of sunlight?
the synthesis of organic compounds by bacteria or other living organisms using energy derived from reactions involving inorganic chemicals, when there's no sunlight. hydrogen sulfide
5: What is primary productivity a measure of?
synthesis of organic materials, grams
6: Looking at the map of productivity around the world- Discuss what you see:
a mass of colors on earth
Why is productivity higher near the coasts of continents than in the open oceans?
because of the nutrients
Why is productivity higher near the poles?
Define the following:
Autotrophs:
Organisms that make their own food, also called producers
Heterotrophs:
organisms that must consume other organisms for energy
Trophic pyramid:
a model that describes who eats whom
Primary consumers:
these organisms eat producers
Secondary Consumers:
these organisms eat primary consumers
Top consumers:
the top of the trophic pyramid
7: In a food web, what do the arrows represent?
the flow of energy
8: What are some atoms and molecules that cycle in biogeochemical cycles?
carbon, oxygen, phosphorus, nitrogen, sulfur
9: Diagram the Carbon Cycle in the Ocean:
10: Diagram the Nitrogen Cycle in the Ocean:
11: Diagram the Phosphorus Cycle:
12: What is a limiting factor in ecosystems?
13: What are the most important physical factors for marine organisms?
14: What are some biologic factors that affect ocean organisms?
15: Define the following zones:
Euphotic:
Disphotic:
Aphotic:
16: Define the following nutrient transports:
Diffusion:
Osmosis:
Active Transport:
18: What are the major zones of the ocean?
(see assignment below)
19: What is natural selection?
20: Who was Carolus Linnaeus? What did he do?
21: What is taxonomy?
22: What are the 6 kingdoms and how are they further divided?
