Question

The rate of primary productivity is equal to the rate of secondary productivity.
Select one:
True
False

Answer 1

well they sound like 2 different things so i would say false

Answer 2

ok... i have some more :|

Answer 3

ask away mate

Answer 4

Which of the following statements is true about photosynthesis and cellular respiration?
Select one:
a. Both processes use oxygen as a reactant.
b. Plants perform photosynthesis.
c. Plants perform cellular respiration.
d. Plants perform both photosynthesis and cellular respiration.

Answer 5

well seeing as photosynthesis occurs in chloroplasts, and cellular respiration occurs in mitochondria which means that the chemical equations for the processes are opposite of each other i would day that d. Plants perform both photosynthesis and cellular respiration.

Answer 6

ohk :)

Answer 7

Unlike photosynthesis, cellular respiration:
Select one:
a. is an energy conversion
b. does not require the intake of carbon dioxide
c. involves primarily plants
d. uses chlorophyll

Answer 8

hmmm research is proving a difficulty, they use chlorophyll and sunlight and glucose

Answer 9

photosynthesis ofc epitomises plants

Answer 10

plants breathe in co2 and emit o2

Answer 11

so i guess A

Answer 12

ok. yeh :)

Answer 13

Select one:
a. pyramid
b. dodecahedron
c. sphere
d. parabola

Answer 14

pyramid

Answer 15

hah :) ok

Answer 16

While primary production refers to the synthesis of plant material, secondary productivity refers to the synthesis of:
Select one:
a. water.
b. ecosystems.
c. all abiotic factors.
d. animal tissue.

Answer 17

Secondary production is the generation of biomass of heterotrophic (consumer) organisms in a system. This is driven by the transfer of organic material between trophic levels, and represents the quantity of new tissue created through the use of assimilated food.

Answer 18

'tis the rate of biomass formation or energy fixation by heterotrophic organisms, such as grazers and decomposers

Answer 19

so its D?? :|

Answer 20

indeed

Answer 21

For most ecosystems, the ultimate source of energy is:
Select one:
a. plants.
b. producers.
c. the sun.
d. water.

Answer 22

@PRAETORIAN.10

Answer 23

the sun bro :D

Answer 24

whats the next question?

Answer 25

Select one:
a. Erosion
b. Fixation
c. Combustion
d. Weathering
