Living things come from other living things through either sexual or asexual reproduction.
Iteru [2.4K]

Explanation:

Organisms don’t have to only reproduce sexually or only reproduce asexually - some animals do both!

When conditions are good, such organisms will reproduce asexually because it is easier. For example, starfish (by fragmentation), slime molds, and water fleas/daphnia (by parthenogenesis) all reproduce asexually when there is plenty of food, minimal predators, and not too much crowding of individuals of the same species.

When conditions worsen (less food, too many individuals, etc), they may switch to sexual reproduction in order to add genetic variation to their population and ensure survival through difficult times.

konstantin123 [22]
When energy passes from one trophic level to the next, I would guess that the two factors which decrease the total amount of energy from being passed up are: 
1. An organism does not assimilate all the energy of food consumed. Within a consumer, digestion and assimilation of energy is not 100% efficient: some of the energy is lost.
2. A large proportion of energy assimilated by a producer and consumer is lost through respiration, i.e., day-to-day maintenance of metabolic processes.
