test 3

Question 1

photosynthesis equation

Answer 1

carbon dioxide + water (with sunlight)=glucose+oxygen

Question 2

2 elements found in all molecules

Answer 2

carbon and hydrogen

Question 3

what small molecule goes with protein

Answer 3

amino acid

Question 4

what small molecule goes with cellulose and starch

Answer 4

glucose

Question 5

small molecule with lipids

Answer 5

glycerol and fatty acid

Question 6

how does sea grass make carbohydrates

Answer 6

light and water contribute to photosynthesis, making carbon into glucose. Glucose is a carbohydrate

Question 7

define productivity

Answer 7

the rate of production of biomass per unit area of volume. Results From chemosynthesis and photosynthesis

Question 8

one biological molecule that has both elements

Answer 8

dna

Question 9

nitrogen is essential to make what? phosphorus and what are essential nutrients?

Answer 9

proteins and DNA/ calcium

Question 10

suggest how biomass pyramids change from runoff

Answer 10

algae bar would be narrower, but limpet would become wider. This is because the limpets would rapidly repopulate before the algae had time to catch up

Question 11

why can increased algae lead to death of marine animals

Answer 11

Require more oxygen, meaning less is available for others, They can become parasitic to animals if they attach and can harm them. It also causes an increase in decomposers

Question 12

algae and bacterium

Answer 12

mutualistic

Question 13

what are the effects of a mutual relationship between algae and bacterium

Answer 13

both species benefit. The toxin protects the algae from predators and in return the bacterium gets a habitat. This also allows for increased growth of bacterium

Question 14

describe the role of diatoms

Answer 14

feeding consumers at higher levels. They make glucose from water and carbon dioxide

Question 15

why are blue sharks carnivores predators

Answer 15

they kill other marine life for food, specifically those that are smaller than them. Because their prey are consumers, they are carnivores

Question 16

relationship between sea anemones and clownfish

Answer 16

mutualistic, both organisms benefit. Clownfish feed on anenomie eggs

Question 17

two nutrients required by photosynthetic marine organsims

Answer 17

nitrates and magnesium

Question 18

role of decomposers in recycling nutrients

Answer 18

breaks down dead, decaying matter such as: bacteria. so it can return to the food chain for producers. Externally digest minerals and new organisms can take its place.

Question 19

how to find percent increase in a region

Answer 19

subtract small from big and divide by small.

Question 20

why does an area have the greatest percent change

Answer 20

there is less productivity in this region, fewer photosynthetic organisms up taking nitrates, and low light penetration

Question 21

differences in data after a strong wind storm

Answer 21

strong surface currents, causes upwelling, and increases nitrate concentration

Question 22

explain the effect of an increase in surface concentration of nitrate ions on the concentrate of dissolved oxygen

Answer 22

increased photosynthesis causes increased dissolved oxygen due to increased productivity of producers.
