Question

No population can grow indefinitely. The ultimate size of any population is limited by:
A. The carrying capacity of its environment.
B. Its birth rate.
C. Its intrinsic growth rate.
D. Reproductive isolation.

Answer 1

Hint: No population can grow indefinitely due to limited coffers similar to light, water, and nutrients and because of challengers or predators. The biotic eventuality is the population's capacity forgrowth.Human population, now nearing 8 billion, can not continue to grow indefinitely.


Complete step by step solution:
Birth Rate: Birth rate is the number of individualities born in a population in a given quantum of time. The mortality rate is stated as the number of individuals born per time per 1000 in the population. For illustration, if 35 births occur per time per 1000 individualities, the birth rate is 35. Birth Rate( or crude birth rate) The number of live births per,000 population in a given time. Not to be confused with the growth rate.
Intrinsic growth rate: The outside per capita growth rate for a population is called the natural rate of increase. As a population grows in an area, a population may witness the goods of increased consistency. In a given area, the maximum population size of the species that the terrain can sustain is called the carrying capacity. The natural rate of increase, as defined in the exponential equation, isn't a constant number at all but rather is itself a function of the viscosity of the population.
Reproductive isolation: The mechanisms of reproductive insulation are a collection of evolutionary mechanisms, actions and physiological processes critical for speciation. They help members of different species from producing seed, or ensure that any seed is sterile.
Carrying capacity: Carrying capacity can be defined as a species' average population size in a particular niche. The species population size is limited by environmental factors like acceptable food, sanctum, water, andmates.However, the population will drop until the resource rebounds, If these requirements aren't met.
There are limits to the life- sustaining coffers earth can give us. In other words, there's a carrying capacity for mortal life on our earth. Carrying capacity is the maximum number of a species an terrain can support indefinitely.
Hence, Option A is the correct answer.

Note:
Limitations to population growth are either viscosity- dependent or viscosity-independent. viscosity-dependent factors include complaint, competition, and predation. viscosity- dependent factors can have either a positive or a negative correlation to population size. Carrying capacity, or the maximum number of individualities that a terrain can sustain over time without destroying or demeaning the terrain, is determined by many crucial factors: food vacuity, water, and space.
