If there are 10,000 kCal of energy available in the producers, how much energy would be available to each of following levels of consumers? Explain what happens to the energy as it moves from producer to the tertiary consumer.

Primary Consumer - 1000 kCal

Secondary Consumer - 100 kCal

Tertiary Consumer - 10kCal

Explanation:

Each time a consumer consumes the previous organism, the energy that is consumed is ten percent of the last one. This is called the ten percent rule.

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.
