The diagram is a model of an energy pyramid of an ecosystem. Primary producers are modeled by a wide rectangle labeled 100 percent. Above them are first-level consumers and a narrow rectangle labeled 10 percent. Then second level consumers at 1 percent, and on top the third-level consumers at 0.1 percent.

The levels of the diagram are labeled with percentages. What do the percentages represent?

A. the average energy requirement of organisms in each trophic level
B. the relative amounts of energy contained by the organisms in each trophic level
C. the energy lost as heat from one trophic level to the next
D. the rate of conversion of light energy to chemical energy

B

Explanation:

Amount of energy decreases as it goes higher up the trophic levels.

the food storage products of chrysophytes are oils or the polysaccharide laminarin.   formerly classified as plants, the chrysophytes contain the photosynthetic pigments chlorophyll a and c all but the yellow-green algae also contain the carotenoid pigment fucoxanthin.

homeostasis is the tendency towards a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes. and this is how it applies to the integumentary system. back to top. skin functions in homeostasis include protection, regulation of body temperature, sensory reception, water balance, synthesis of vitamins and hormones, and absorption of materials. when body temperature falls, the sweat glands constrict and sweat production decreases.
