What is Catching or removing from a population more organisms than it can replace is called?
Catching or removing more organisms from a population than it can replace is known as overfishing or overharvesting. This practice can lead to a significant decline in species populations, disrupting ecosystems and reducing biodiversity. It poses a threat to the sustainability of fisheries and can have long-term ecological and economic consequences. Effective management and conservation strategies are essential to prevent such depletion.
How will the tree population change if all other organisms were removed?
If all other organisms were removed, the tree population could initially thrive due to the absence of competition for resources and reduced herbivory. However, over time, the lack of pollinators and seed dispersers would hinder reproduction and genetic diversity, leading to a decline in tree population. Additionally, without other organisms, ecosystems would become imbalanced, potentially affecting soil health and nutrient cycling, ultimately threatening the long-term survival of tree populations.
What factors determine whether a population would thrive or decline?
Factors such as availability of resources, competition, predation, disease, environmental changes, and genetic diversity can impact whether a population thrives or declines. Populations that have access to abundant resources, low competition, and effective defense against predators and diseases are more likely to thrive, while populations facing scarcity, high competition, or environmental stress are more likely to decline. Additionally, genetic diversity within a population can influence its ability to adapt to changing conditions.
What makes a natural disaster a limiting factor density independent?
A natural disaster is considered a density-independent limiting factor because its impact on a population does not depend on the population's size or density. Events such as hurricanes, earthquakes, and wildfires can affect large areas and populations regardless of how many individuals are present. This means that even in low-density populations, a natural disaster can cause significant mortality and disruption, leading to a decline in population numbers without being influenced by the population's density.
What are some reasons populations grow stay the same and decline?
Populations can grow due to factors like improved healthcare, increased birth rates, and migration. They may stabilize when birth rates equal death rates, often seen in developed countries with access to education and family planning. Declines can occur due to high mortality rates, low birth rates, economic challenges, or significant emigration. Additionally, aging populations can lead to a decrease in the workforce, further contributing to population decline.
How are a population and community different?
A population biologist studies the number(s) of species as they increase or decline in relation to their density or some environmental factor. Community ecologists study the numbers and interactions of all the species in a given location.
When lemming populations decline populations of arctic foxes decrease. The limiting factor on the population of arctic foxes is .?
Food availability is a determining factor.
When lemming populations decline populations of Arctic foxes also decrease. The limiting factor on the population of Arctic foxes is?
Food availability is a determining factor.
How can populations change?
Populations can change through birth (increasing population), death (decreasing population), immigration (increasing population), and emigration (decreasing population). Changes in these factors can result in population growth or decline over time.
When lemming populations decline populations of Arctic foxes also decrease so what is the limiting factor on the population of Arctic foxes?
Food availability is a determining factor.
How would the population of animals in a prairie community be affected if one is a overhunter?
The population of animals in a prairie community would be negatively affected if one is over hunted because it would change the populations of the other species. This makes the ecosystem unbalanced.
When lemming populations decline populations of Arctic foxes also decrease. The limiting factor on the population of Arctic foxes is . exponential density-independent density-dependent abiotic?
Food availability is a determining factor.
Why when lemming populations decline do populations of Arctic foxes also decrease?
One of the Arctic Foxes' main sources of food is the Lemming. When there are abundant lemmings the Fox has food to raise large litters and the population of Foxes increases. Similarly the numbers of Foxes that can be fed decreases when the lemming population declines because there is less food for the Foxes. Basically the population of any animal is controlled by its food supply.
How are organisms and populations affected by environmental changes?
Organisms may experience changes in their habitat, food availability, and climate due to environmental changes, which can lead to shifts in behavior, reproduction, and distribution. Populations may decline if they cannot adapt to these changes, leading to reduced genetic diversity and increased vulnerability to diseases and other threats. Adaptation, migration, and extinction are some of the responses organisms and populations may have to environmental changes.
How are people affect the Amazon by hunting?
Hunters can affect the amazon by hunting because the population of species they are hunting can majorly decline. Thus, making other populations decline because the food chain no longer applies.
Why does wolf population on isle royale decline following a decline in the moose population?
The decline of moose population followed sooner or later by a decline in the wolves population because the is less for the wolves.
How are changes in populations related to the availability of an ecosystems resources?
Changes in populations are directly related to the availability of an ecosystem's resources. When resources are abundant, populations can grow. If resources become scarce, populations may decline or face competition, which can lead to changes in population dynamics, such as migration or adaptation to find alternative resources.
