The vast majority of eggs are eaten before hatched and the vast majority of hatchlings (fry) are eaten befaore reaching sexual maturity.
Because they have a large, stable population.
It is difficult to provide an exact number as the population of tuis can fluctuate. Tuis are native to New Zealand and are not considered endangered, so their population is relatively stable.
The population would remain stable. Each pair of parents would be replaced by two offspring, maintaining a constant population size. This scenario assumes a closed system with no external factors impacting population growth.
Asexual reproduction can be advantageous in stable environments where offspring are genetically identical to the parent, ensuring successful adaptation to current conditions. It also allows for rapid population growth since there is no need to find a mate.
The male bilharzia parasite, or Schistosoma, holds the female worm within a structure called the gynecophoral canal. This adaptation allows the male to provide a stable environment for the female, facilitating reproduction. By remaining close, the male ensures that the female can produce eggs efficiently, which is crucial for the parasite's lifecycle and successful transmission to new hosts. This pairing enhances the likelihood of survival and propagation of the species.
differances between stationary population and stable population
No, the population is stable.
Because it produces a pulse (temporary state) when triggered and goes back to zero (stable state).
Stable
It is unclear when the human population and the population growth will reach a stable constant. Everyday people are having children or the elderly are dying, this changes the population count.

Compared to other countries in Africa, Ghana is not overpopulated but has had a huge explosion in population since 1950 when there was about 5 million people to now where there is around 25 million. Ghana is rich in resources and is one of the biggest gold producers in Africa and also produces oil. This wealth does not flow to the population where income can be as low as $2 a day. This wealth has attracted many immigrants from neighboring countries and this has added to the big increase in numbers. The country has remained fairly stable and the capital Accra is (on African standards) a thriving modern city. The big population is the result of 3 things. Firstly a stable economy where there has been the ability for family life and the birth of children. Second, the need for a big family to support the parents in old age (there is no social security). Third, the influx of immigrants.

The population will remain stable
They are a stable population, not endangered yet.
