Do you think the spotted salamander and Elysia chlorotica completely meet the autotroph definition? Explain your response.

No

Explanation:

An autotroph is an organism that manufactures its own food all by itself. They take inorganic materials from the environment and produce organic substance which they rely on. There are two special categories of autotrophs which are: chemoautotrophs and photoautotrophs.

No

Explanation:

The spotted salamander and Elysia chlorotica must eat algae, or have algae in their bodies, to benefit from photosynthesis. They require a partnership with an autotrophic organism to have this ability. So, they don’t completely meet the definition of an autotroph.

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.
