What are the two processes used by producers to obtain energy
MariettaO [177]
Answer;
The two processes used by producers to obtain energy are photosynthesis and chemosynthesis.

Explanation; 
Producers are those organisms that can make their own energy in an ecosystem using biochemical processes. These biochemical processes are photosynthesis and chemosynthesis.
Photosynthesis involves use of energy from the sunlight together with water and oxygen to make simple sugars. The process converts solar energy to chemical energy (simple sugars). 
Chemosynthesis involves use of chemicals as the energy source, rather than sunlight , to make simple sugars such as glucose. 
Glucose from both processes is then used for respiration to generate energy or stored in form of starch.

mafiozo [28]

Answer:

8900 CFU/mL

Explanation:

Colony Forming Units (CFU) is a value that indicates the degree of microbiological contamination of an environment. It expresses the relative number of microorganisms of a given taxon in a volume of one cubic meter of water.

UFC is the minimum number of separable cells on the surface, or inside, of a semi-solid agar medium that results in the development of a visible colony of the order of tens of millions of descending cells. The CFUs can be pairs, chains or clusters, as well as individual cells. Colony forming unit.

Calculation

Colonies * Dilution = CFU/mL

89          *  (100/ 1 mL) = CFU/mL

8900 CFU/mL
