Question

energy flows into the biological world from the
multiple choice
volcanoes
sun

Explanation:

In the biological world, the primary source of energy is the sun. Photosynthetic organisms (like plants) capture solar energy and convert it into chemical energy, which then flows through food chains. Volcanoes, large animals, and oceans (assuming the last option is "oceans") do not provide the initial energy input to the biological world on a large - scale, sustainable basis as the sun does.

Answer:

B. sun (assuming the options are labeled A, B, C, D with A: volcanoes, B: sun, C: large animals, D: oceans)
