Connective tissue is a combination of cells and matrix. Describe the properties that the matrix adds for each of the following connective tissue types:
Connective tissue type
Properties of matrix
Blood
Bone
Tunica externa
(external layer of blood vessel)
Dense fibrous
(found in ligaments and tendons)

explanation:

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle

are tertiary consumer and the shrimp are primary consumer, so to balance

mass of shrimp (1/0.1) / 0.1 = 100 kg 

the answer would be   10%
