Afina-wow [57]

The complete question is:

If these organisms were arraigned in a food pyramid, which organism would have the least amount of total energy available?

  • Producers
  • Carnivore
  • Herbivores
  • Top predators

Answer: Top predators

Explanation:

The top predators get the least energy because according to the 10 per cent law the energy transfer only 10 energy is transferred to the next successive level.

The next level of the organism receives only 10 of the total energy that the previous level has.

Hence, the top predators have the least amount of energy in it as the energy is transferred through various levels before reaching top predators.

What posture is a dog displaying if she is leaning away from your, body lowered, ears back, tail down, showing whites of her eye
Brrunno [24]

Answer: Fearful and worried posture

Explanation:

Since dogs cannot talk, their body languages are used to interpret whatever emotion or feeling they may be experiencing.

When a dog is afraid, she tries to look small. She lowers her body and and leans away so that her center of gravity is over her hind legs to  make a quick retreat easy. She also puts her tail down and ears flattened back to her skull. Her eyes also look rounder than normal and she shows the whites of her eyes (whale eyes).

All these tell that a dog is scared and worried or feeling tense.
