PLEASE HELP!!! Do you think the number of animals that eats plants is related to the number of plants?

mina [271]

Answer:

Yes

Explanation:

As the number of animals that eat plants increase, the number of plants decrease. This is because the animals are eating a larger and larger number of plants and reducing the population.

When the number of plants gets too low, the animals will not be able to survive, and they will start to decrease in numbers. In turn, the plants will increase again. Eventually, they will reach an equilibrium.

Silver has a density of 10.5 g/cm³, and gold has a density of 19.3 g/cm³. Which would have a greater mass, 5 cm³ of silver or 5

Vedmedyk [2.9K]

Gold have a greater mass

<h3>Further explanation </h3>

Density is a quantity derived from the mass and volume

Density is the ratio of mass per unit volume

The unit of density can be expressed in g/cm³ or kg/m³

Density formula:

$\large {\boxed {\bold {\rho ~ = ~ \frac {m} {V}}}}$

ρ = density

m = mass

v = volume

mass of Silver :

$\tt mass=\rho\times V\\\\mass=10.5\times 5=52.5~g$

mass of Gold :

$\tt mass=\rho\times V\\\\mass=19.3\times 5=96.5~g$
