Answer:

A- producers provide energy to all of the other organisms. they directly supply energy to primary consumers (animals who eat plants). They indirectly supply energy to other consumers by feeding the animals that they eat. The energy gets transferred from the producers to the primary consumers, to the secondary consumers, and to the tertiary consumers.

B- aphids and slugs both eat producers. if the aphid population decreases, there will be less competition for the slugs to eat the their food.

A flask that weighs 450 g is filled with 145 ml of benzene. The weight of the flask and benzene is found to be 754 g. From this
vaieri [72.5K]

Answer:

Density, d=2.09\ g/cm^3

Explanation:

Given that,

Mass of a flask is 450 g

Volume of benzene added to the flask is 145 mL or 145 cm³

The weight of the flask and benzene is found to be 754 g.

We need to find the density of the benzene.

Weight of benzene added = total weight of flask and benzene-mass of flask

m = 754 g - 450 g

m = 304 g

Density = mass/volume

So,

d=\dfrac{304\ g}{145\ cm^3}\\\\d=2.09\ g/cm^3

So, the density of the benzene is 2.09\ g/cm^3.
