What is a term that describes why some individuals produce more offspring than others?
Organisms that are constantly exposed to dangers, which can kill them in mass, have evolved to reproduce in high numbers so that enough of a species will survive and continue the species. Survival of the fittest and natural selection is a common practice among organisms that reproduce fast and in high numbers.
Organisms that reproduce asexually and sexually?
All the Coelenterates that I know of (jellyfish, sea anemones, etc) and some Platyhelminthes (flatworms). There are undoubtedly others, but I can't think of them offhand.
Do most species produce far more offspring than will survive?
According to evolution, every organism on the planet produces more offspring than can possibly survive. See Charles Darwin's The Orgin of Species.There is variation among species in the amount that survive. If you're looking for an organism with a high death rate look at plants who produce thousands or millions of seeds. Not every one of these matures into an adult. Many are picked out by birds and other animals.
What are osmotolerance organisms?
Organism which can withstand high concentrations of solute.
Small rounded thick-walled resting cell?
I believe that you are referring to a bacterial endospore. Only a small number of bacteria can produce these (Gram-positive Firmicutes). Endospores are very tough and allow the bacteria that can produce them to survive high temperatures, pressures, drought, etc.
Mammals produce high or low numbers of offspring?
Mammals produve low number of offspring.
Why do mammals produce high and low numbers of offspring?
Mammals produce a low number of offspring. Take humans, cats or dogs for example xHope i helped ;P
What evidence is there that veritable produce high and low numbers of offspring?
no
What evidence is there that vertebrates produce high numbers of offspring?
because it is an organism
Do mammals produce high or low numbers of offspring?
It depends on the size of the mammal.

Why do fish produce high numbers of offspring?
some eggs are eaten or babies dont survive
Why Frog produce a large number of gametes?
Frog spawn has a high mortality rate because of predators and other factors. Therefore the more offspring the frogs have, the greater the chance the offspring have of reaching maturity and continuing the species.
Do clams produce high numbers of offspring?
Yes, especially the zebra clam living in the locks in the Mississippi river.
What evidence is there that vertebrates produce high snd low numbers of offspring?
because some vertebrates that have high offs doesnt drink many milk so her bones break when they have many babys.
What are the characteristics of a r-strategists?
¨Produce numerous offspring at once ¨Short gestation period ¨Less resources spent per offspring ¨Offspring hatch or born capable of surviving on their own ¨Have small bodies ¨Mature fast and have short lifespan ¨Able to disperse offspring widely ¨Death rate generally not correlated with density of population ¨Population size fluctuates and not stable ¨Occupies a generalist role in ecology ¨Main idea is to use a high reproductive rate to high mortality rate ¨Produce numerous offspring at once ¨Short gestation period ¨Less resources spent per offspring ¨Offspring hatch or born capable of surviving on their own ¨Have small bodies ¨Mature fast and have short lifespan ¨Able to disperse offspring widely ¨Death rate generally not correlated with density of population ¨Population size fluctuates and not stable ¨Occupies a generalist role in ecology ¨Main idea is to use a high reproductive rate to high mortality rate
What is a reproductive strategy in biology?
the way that a species creates offspring Reproductive strategies are theories associated with the natural selection of factors associated with the number of young produced ... or parental care of offspring. Books have been written on this topic. The simple answer is best described by a few examples. There are basically 2 extremes with this theory ... one is " K selection," which refers to a strategy of producing few offspring, but providing high levels of parental care to ensure survival of young and greatly increase the probablilty that they will reproduce. Good examples include man, primates, and elephants ... produce few offspring but have prolonged periods of parental care. The other exteme is "r selection," which refers to a strategy of producing high numbers of offspring but very little parental care. The idea here is that by producing a huge number of offspring survival of the species will be enhanced even with a small percentage of survivors ... i.e., if a large number is produced, even with a small percentage of survival the number of survivors is substantial. Good examples include many species of insects and some fish. Carp, for example lay over a million eggs and abandon the egg masses. Even if only one tenth of one percent survive, that one carp produced 1,000 offspring that are potential breeders (if they survive to reproductive age). Most organisms have a reproductive strategy that is somewhere between these 2 extremes ... but most lean toward one or the other.THE METHOD AN ORGANISM USES TO PRODUCE OFFSPRING!!! - Apex :3
