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.

What is the correct formula for combining Mg2+ and Br1+

True [87]

Answer: The correct formula is $MgBr_2$

Explanation:

For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.

Here magnesium is having an oxidation state of +2 called as $Mg^{2+}$ cation and bromine $Br^{-}$ is an anion with oxidation state of -1. Thus they combine and their oxidation states are exchanged and written in simplest whole number ratios to give neutral $MgBr_2$ .

The cations and anions being oppositely charged attract each other through strong coloumbic forces and form an ionic bond.

The amount of carbon dioxide (in pounds per 15,000 cubic miles) released by a certain SUV depends on its fuel efficiency accordi

Shtirlitz [24]

Answer:

30 miles per gallon.

Explanation:

See picture

When the amount of carbon is plotted based on efficiency, the following graph is obtained (see image)

when looking at the graph, it can be seen that the point of lowest emission is presented with the maximum possible efficiency, 30 miles per gallon and this value is 10400 pounds per 15000 cubic miles.

$W=32x^{2}-2080x+44000$
