somemore ecosystem

Question 1

Whats photosynthesis

Answer 1

process of plants making their own food. produce glucose/ C6, H12, O6

Question 2

glucose chemical equation

Answer 2

C6, H12, O6

Question 3

photosynthesis chemical equation

Answer 3

H2O + CO2 + ▵H –> C6, H12, O6 + O2

Question 4

Respiration

Answer 4

body releasing energy.
need: O2,H12, O6
produce: ▵H, CO2, H2O

Question 5

Respiration chemical equation

Answer 5

C6, H12, O6+ O2–> ▵H+CO2+H2O

Question 6

Biotic factors

Answer 6

Anything living or once living in an ecosystem

Question 7

Answer 11

Performs respiration

Question 12

Food chain

Answer 12

One chain in the food web starting with the producers and going up the top consumer level

Question 13

Food web

Answer 13

All the predator-prey interaction in an community

Question 14

Primary Consumer

Answer 14

Eats producers in a giving food chain
1st level

Question 15

Secondary Consumer

Eats primary consumers in a giving food chain
2nd level

Question 16

Tertiary Consumer

Answer 16

Eats secondary consumers in a giving food chain
3rd level

Question 17

Answer 17

Top of a given food chain
Can be at any level

Question 18

Carnivore

Answer 18

Secondary consumer and above (not primary consumer)
Eats consumers only

Question 19

Herbivore

Answer 19

Primary consumer only
Eats producers only

Question 20

Omnivore

Answer 20

Eats at all consumer levels
Eats producers and consumers

Question 21

What happens to the energy at higher consumer levels?

Answer 21

Only 10% of energy goes to next level. 90% used for daily activities
4th consumer level is usually the highest level because of limited amount of energy
Reason why there is less organisms at higher levels
triangle thing - primary producer to apex predators

Question 22

energy and matter transfer

Answer 22

most energy from ecosystems comes from sunlight

Question 23

food web

Answer 23

consist of overlapping food chains

energy availability

Answer 25

limits how many different levels a food chain has.
