Yes an ocean energy pyramid consists of microscopic organisms called plankton at the base, then mussels, crabs, lobsters, and finally seals. of which organism would you expect to find the fewest? a. plankton b. mussels c. lobsters d. seals

The correct assertive is letter D- Seals

Explanation:

  An energy pyramid indicates energy is passing by along the pyramid. This

energy goes down along the process. For instance, it starts with 5x with the

planton, and after that 4x with mussels, 3x with crabs, 2x with lobsters and

finally X with Seals, that receives less energy than all the member of this feed

chain. It happens because the energy  is incorporated by each trophic level

and the other part is dissipates as heat. That's the reason the correct

assertive is letter D (the last trophic level about this feed chain or ocean

energy pyramid) and consequently is going to be the animal you will find the

fewest.

i think the answer is b.

answer-

the statement that f(x) = |x+a| + b has exactly one x-intercept is sometimes correct.

solution-

it solely depends on b, whether the function will have one or two or zero x intercept.

this plot of the given function, f(x) = |x+a| + b will be the basic absolute value graph i.e v shape, with vertex translated to (-a, b), instead of origin.

1-   if b is zero, the graph will have exactly one x-intercept, at x= -a

2- if b is positive, the whole graph will be above the x-axis, hence it will have no x-intercepts.

3- if b is negative, the graph will be below the x-axis, hence it will have two x-intercepts.

∴ the statement is sometimes true.
