The correct answer is option Energy is lost at each trophic level.
In a Ecological pyramid, the energy is transferred from the producer to the consumer level. The ecological pyramid is triangular in structure, this is because the number of organism on each successive trophic level is less than the preceding one or the one below it.
The reason of this shape of ecological pyramid is on subsequent trophic level, the amount of energy transferred is only 10%. The rest of the energy is dissipated in the environment in the form of heat. As only 10% of total energy is transferred to the subsequent level, The amount of energy reaching to tertiary consumer is very less that it cannot meet the energy demand of next level.
Answer:
The correct answer is luteinizing hormone.
Explanation:
Hypothalamus has two sets of nerve cells that produce hormones. One set sends the hormones that are anti-diuretic hormone and oxytocin. ADH regulates or water in the bloodstream by reabsorption of water at the kidney and oxytocin helps in pregnancy and breastfeeding.
The other set produces hormones growth regulating, stress releasing and stimulating and inhibiting hormones are dopamine, corticotrophin-releasing hormone, growth hormone-releasing hormone, gonadotropin-releasing hormone, somatostatin, and thyrotropin-releasing hormone.
Luteinizing hormone is secreted by the pituitary gland. It is one of the main hormones that control the reproductive system.
Thus, the correct answer is luteinizing hormone.

The answer is B because:
Cell walls are made of cellulose and proteins (hence II).
Animal cells don't have cell walls (only cell membrane) but plant cells do so IV
They must be semipermeable since materials for example carbon dioxide and water for photosynthesis have to go into the cell <em>some</em> way.
