Question

What percentage of caterpillars original energy is available to the hawk?

Answer 1

Answer:

0.6%.

Explanation:

The question seeks to check how energy flow through an ecosystem using an ecological pyramids with calories abundance available to the primary producers to those available to the tertiary consumers. The pyramid also use the are in segments as values in the pyramid are per square meter per year.

Given in the pyramid below;

A– Energy of hawk (tertiary consumers)= 24kcal

C– Energy of caterpillar (primary consumer) = 4000kcal

Percentage of caterpillars original energy is available to the hawk =

A/C × 100%

i.e.

24 kcal/4000 kcal x 100 = 0.6%.

Answer 2

Answer:

The percentage of caterpillars original energy available to the hawk is  = 0.6%.

Explanation:

the answer above is given by; 24 kcal/4000 kcal x 100

Caterpillars are the larval stage of members of the order Lepidoptera. As with most common names, the application of the word is arbitrary, since the larvae of sawflies are commonly called caterpillars as well. Both lepidopteran and symphytan larvae have eruciform body shapes.

Hawks are a group of medium-sized diurnal birds of prey of the family Accipitridae. Hawks are widely distributed and vary greatly in size. The subfamily Accipitrinae includes goshawks, sparrowhawks, sharp-shinned hawks and others. This subfamily are mainly woodland birds with long tails and high visual acuity.
