Que rol tiene el ecosistema el patos
zhenek [66]

Answer:

Investigué un poco y descubrí algunas cosas sorprendentes sobre los patos.Espero que los encuentres interesantes:Las aves acuáticas como los patos pueden mantener la diversidad de otros organismos, controlar las plagas, ser bioindicadores efectivos de las condiciones ecológicas y actuar como centinelas de posibles brotes de enfermedades. También proporcionan importantes aprovisionamientos (carne, plumas, huevos, etc.) y servicios culturales a las sociedades indígenas y occidentalizadas.La ubicuidad a menudo ridiculizada de los patos los convierte en vehículos ideales para transportar semillas de un lugar a otro, y eso significa humedales y biodiversidad más saludables para el beneficio de todas las aves y la vida silvestre.Sabías ? :Los patos ayudan al medio ambiente porque limpian los químicos del agua para que sus amigos y otros animales no mueran y se enfermen gravemente.

The unit weight of a soil is 14.9kN/m3. The moisture content of the soil is17% when the degree of saturation is 60%. Determine:
Serggg [28]

Answer:

a) 2622.903 N/m^3

b) 1.38233

c)4.878811765

Explanation:

Find the void ratio using the formula:

y = \frac{G_{s}*y_{w} + w*G_{s}*y_{w} }{1+e} ....... Eq1

Here;

G_{s} is specific gravity of soil solids

y_{w} is unit weight of water = 998 kg/m^3

w is the moisture content = 0.17

e is the void ratio

y is the unit weight of soil = 14.9KN/m^3

Saturation Ratio Formula:

w*G_{s} = S*e  ..... Eq2

S is saturation rate

Substitute Eq 2 into Eq 1

y = \frac{(\frac{S*e}{w}) * y_{w} + S*e*y_{w}  }{1+e}

14900 = \frac{3522.352941*e + 598.8*e }{1+e} = \frac{4121.152941*e}{1+e}\\\\ e= 1.38233

Specific gravity of soil solids

G_{s} = \frac{S*e}{w} = \frac{0.6*1.38233}{0.17} = 4.878811765

Saturated Unit Weight

y_{s} = \frac{(G_{s} + e)*y_{w}  }{1+e} \\=\frac{(4.878811765 + 1.38233)*998  }{1+1.38233}\\\\= 2622.902571 N/m^3
