What else can I help you with?
Can occur when part of a population of a species becomes separated from the remainder they may over time evolve different characteristics from the parent population?
This is known as allopatric speciation. It occurs when a physical barrier separates a population, leading to genetic isolation and ultimately the development of different traits. Over time, this can result in the formation of a new species.
What is the population of sea creatures in the world?
It is estimated that there are over 2 million species of sea creatures in the world, but the total population of all these species is difficult to quantify. The ocean is a vast and diverse environment, making it challenging to accurately estimate the total population of sea creatures.
Ecology that focuses on dynamic changes occurring in one species is?
The study of the dynamic changes occurring in one species is known as population ecology. This field of ecology examines factors such as population size, distribution, growth rates, and interactions with the environment that influence changes in a particular species over time.
Under ideal conditions with unlimited resources how will a population grow?
In ideal conditions with unlimited resources, a population will grow exponentially, increasing indefinitely over time. This is known as exponential growth, where the population size constantly accelerates due to unlimited availability of resources for reproduction and survival. However, in reality, factors like competition, predation, disease, and environmental limitations often prevent populations from growing exponentially.
How do exotic species affect populations of native species?
When exotic species are introduced into an area these species can grow at exponential rate due to a lack of competitors and a lack of predators they may take over niches of native species and can eventually replace the native species completely
This is the way in which a species' population grow and shrink over time?
The growth and decline of a species' population over time is determined by factors such as birth rates, death rates, immigration, and emigration. These factors collectively influence the species' overall population dynamics and can lead to fluctuations in population size. Understanding these dynamics is essential for studying the ecology and conservation of a species.
What are population dynamics?
The ways in which a given population's numbers grow and shrink over time, as controlled by birth, death, and emigrationThe changes in populations through time are known as population dynamics.
Can mountains grow or shrink?
Mountains can both grow and shrink over long periods of time due to tectonic forces such as plate movement and erosion. The process of mountain growth usually occurs over millions of years when tectonic plates push against each other, forcing the Earth's surface to rise. On the other hand, mountains can shrink through erosion caused by weathering and other natural processes that wear down their surfaces.
Why are wolves important for an ecosystem balance?
because if they went there, the population below it on the food chain would over grow and eat out the species below it and the whole ecosystem would colapse.
What happens when a species over produces offspring?
they become over populated and the population declines
What happens when species over produce offspring?
they become over populated and the population declines
Is a humpback whale an endangered species?
No. With a worldwide population of over 80,000 the humpback is listed as a species of least concern.
Does an individual a population or a species evolve?
A species evolves over time through the process of natural selection acting on individuals within a population. Individuals themselves do not evolve, as evolution refers to changes in the genetic composition of a population over generations.
How might the presence of a chemical mutagen affect the genetic size of a population over time?
It affects the population because mutations can be deadly and they're passed down from one generation to the next making the population shrink.
Which unit of organism evolves and individual a population or a species?
Evolution occurs at the population level, not at the level of an individual organism or a species. Changes in gene frequencies within a population over time drive the process of evolution.
What is dioscoreae?
Dioscorea is a genus of flowering plants. This genus has over 600 species. Most of the species are tropical, but there are a few that grow in temperate climates.
What would happen to the population of animals if humans didn't exist?
their populations would grow and grow and finnally take over
