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.
The right answer for the question that is being asked and shown above is that: "B. birds have beaks adapted to break open hard shells." The adaptation would most likely be found in organisms living in the rainforest is that <span>birds have beaks adapted to break open hard shells</span>
Answer:
B. only the animals living in water
Answer:
The man's father genetics for aniridia is XAY because one copy of the altered gene in each cell is sufficient to cause this disorder.
Explanation:
The aniridia allele in females has to be in the XAXA or XAXa form to be expressed but in males, can be expressed when genotype is XAY.
Migraine headaches allele in females has to be in the XMXM or XMXm form to be expressed but in males, can be expressed when genotype is XMY.
A man with normal vision and without migraines (XaY/XmY) had a father who had aniridia (XAY).
The man's father genetics for aniridia is XAY because one copy of the altered gene in each cell is sufficient to cause this disorder.
