10% energy was passed on if the producer has 40,000 kcal of energy and the primary consumer 4000 Kcal.
The right answer is option 2.
Explanation:
The producer is the initiator of food chain in a food chain and pyramid.
The amount of energy transferred or pass on to the other level or higher level is 10%. The 90% percent energy is being consumed by organism of the trophic level in carrying out metabolic processes, reproduction etc.
The heat gets dissipated only a small amount reaches the other trophic level.
This logic is also called 10% rule of energy transfer.
So, the producer has 40,000 Kcal of energy
primary consumer comes just after producer as it is a herbivore.
so,
x 40000
= 4000 Kcal
Thus 10% of the energy is passed on.

Answer:
Multicellular organisms depend on mitosis for growth and repair. When an animal, plant or other multicellular organism grows, it makes more cells through mitosis. Organisms can repair some of their tissues, using mitosis to regenerate new cells.
