Sexual reproduction is performed through gametes which means that each cell has half the number of chromosomes (for humans that's 23) . also called haploids, when the two cells combine the chromosmes cross creating a whole set of chromosomes. (46 in humans)
asexual reproduction is done through meiosis through somatic cells that already have two sets of chromosomes. (46 in humans) they duplicate the chromosomes and then spilt to create a perfect duplicate. the cells can also be know as diploids.
Answer:
The correct option is<em> b. at each step, energy is lost from the system</em>
Explanation:
The amount of energy that travels from one trophic level to another is known to declines at each level. Infact, only 10% of the energy travels from one trophic level to another.
This is because most of the energy is lost by the organisms at each trophic level. It is due to the metabolic processes which occur in the organisms of each trophic level and most of the energy is lost as heat.
