In a typical food chain, what would happen after a primary
consumer eats a producer?

They would only gain a small portion of energy from the producer

Step-by-step explanation:

This isn't Math however, if what you are talking about is science, then I'd say that energy is lost during the food chain and those that eat their producers or consumers only get a small portion of that energy they have.

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.

step-by-step explanation:

the true ones are a b and d
