bio chap 6

Question 1

phototrophs

Answer 1

organisms that capture energy from sunlight
***use energy of sunlight to convert CO2 and H20 into sugar and oxygen, sugars have energy that synthesizes ATP, thus giving energy.

Question 2

chemotrophs

Answer 2

organisms deriving energy directly from organic molecules like glucose, (Animals)

Question 3

autotrophs

Answer 3

“self feeders”, make their own organic sources of carbon (Plants, photoautotrophs)

Question 4

heterotrophs

Answer 4

organisms not capable to convert carbon dioxide into organic forms of carbon. Eat other organisms “other feeders” (chemoheterotrophs)

Question 5

photoheterotrophs

Answer 5

microrganisms gain energy from sunlight but get carbon from preformed organic microcules

Question 6

chemoautotrophs

Answer 6

microrganisms extract energy from inorganic sources but build their own organic molecules (extreme environments)

Question 7

Metabolism

Answer 7

is the set of chemical rx that sustain life.

**building and breaking down of sugars such as glucose, and the harnessing and release of energy..

Question 8

catabolism

Answer 8

set of chemical reactions that break down molecules, into smaller units and in the process produce ATP

Question 9

Anabolism

Answer 9

set of chemical reactions, that build molecules from smaller units and require an input of energy, usually in ATP
