What is one biotic factor that affects the size of a population in an ecosystem?

Competition for resources like food and shelter among individuals in a population can affect the population size. Strong competition may limit the availability of resources, leading to a decrease in population size.


When does competition decrease the size of population?

Competition can decrease the size of a population when resources become limited, increasing competition among individuals for those resources. This can lead to reduced access to food, shelter, or mates, ultimately resulting in decreased survival and reproduction rates within the population.


How do interactions between organisms influence populations size?

Interactions between organisms can impact population size through competition for resources, predation, disease transmission, and mutualistic relationships. For example, competition can reduce available resources, leading to a decrease in population size. Predation can also directly affect population size by reducing the number of individuals in a population. On the other hand, mutualistic relationships can benefit population growth by providing advantages such as enhanced resource availability or protection from predators.

What does intraspecific competition do to population growth?

If members of the same species are competing for limited resources, then each individual would receive fewer resources when the population size of intraspecific competitors increases. Fewer resources per individual will(1) decrease the growth rates of individuals,(2) increase the chance that individuals die of starvation(3) decrease the number of offspring that a female can produce.

What takes place when more than one organism seeks the same resources at the same time and it limits population size?

Competition occurs among the organisms, leading to a struggle for resources. This competition can result in a decrease in resource availability, which can ultimately limit the population size of the organisms involved. Over time, this can lead to adaptations in the competing species to reduce competition and carve out their own ecological niche.
