WebJan 23, 2024 · The fecundity rate for plants is understood by studying their seeds. Coconut and chestnut trees have low fecundity rates because the few energy-rich seeds they produce have a good chance of survival. High fecundity plants like orchids produce many seeds that are low in energy, each with less chance of survival.
WebBecause they have better-controlled fecundity and fertility. Many countries such as China even have restrictions to shrink their population on purpose because they are overcrowded. As for underdeveloped countries, they are … WebType 1 organisms have high survivorship throughout life until old age sets in, and then survivorship declines dramatically to 0. Humans are type 1 organisms. Type III organisms, in contrast, have very low survivorship early in life, and few individuals live to old age. Population Growth or Decline
WebHence, producing many offspring decreases fitness in top predators and this trait will have been selected against during evolution.

WebAt low density, plants may receive fewer pollinator visits and⁄or smaller conspecific pollen loads than they would at higher densities, and as a result may produce fewer seeds.
WebFecundity is an organism's reproductive capacity (the number of offspring it's capable of producing).
