Describe The Energy Sourse Of Heterotrophs

Front 1

Describe the energy source of autotrophs

Back 1

Organisms that utilize an inorganic source of carbon (that is, carbon dioxide) as their sole source of carbon are called autotrophs (aw′tō-trōfs), so-named because they “feed themselves.” *1 More precisely, autotrophs make organic compounds from CO2 and thus need not feed on organic compounds from other organisms to acquire carbon.

Front 2

Describe the energy source of Chemoheterotrophs

Back 2

Microorganism that uses organic compounds for both energy and carbon.

Front 3

Describe the energy source of photoautotrophs

Back 3

Microorganism which requires light energy and uses carbon dioxide as a carbon source.

Front 4

Optimum growth temperature

Back 4

Temperature at which a microorganism’s metabolic activities produce the highest growth rate.

Front 5

Minimum growth temperature

Back 5

The lowest temperature at which an organism is able to conduct metabolism

Front 6

Maximum growth temperature

Back 6

The highest temperature at which an organism continues to metabolize . when the temperature exceeds this value, the organism’s proteins are permanently denatured, and it dies

Front 7

Optimum growth temperature for psychrophiles

Back 7

Microorganism requiring cold temperatures (below 20°C).grow best at temperatures below about 15°C and can even continue to grow at temperatures below 0°C.

Front 8

Optimum growth temperature for true mesophiles

Back 8

Microorganism requiring temperatures ranging from 20°C to about 40°C.

Front 9

Optimum growth temperature for thermophiles

Back 9

grow at temperatures above 45°C
