Which of the following represents change to an ecosystem brought about by abiotic factors?

It would be the decrease in plant populations due to a decrease in the available water supply would represent change to an ecosystem brought about by abiotic factors.

What determines the carrying capacity of an ecosystem?

Carrying capacity, or the maximum number of individuals that an environment can sustain over time without destroying or degrading the environment, is determined by a few key factors: food availability, water, and space.

Why is it important to monitor the carrying capacity of ecosystems?

The carrying capacity is a measure of how many individuals can a given ecosystem provide for. An individual and its population is dependent on various components of its ecosystem for necessities such as food, habitat, etc. Thus, ecosystem health is severely affected if the population grows beyond the carrying capacity.

What is the maximum size that an ecosystem can be?

The carrying capacity of an ecosystem is the largest population that it can sustain indefinitely with the available resources, also called the “maximum load” by population biologists. Carrying capacity depends on many abiotic and biotic factors in the ecosystem and some are more obvious than others.

Is migration a limiting factor?

Density Dependent Limiting Factors The density dependent factors are factors whose effects on the size or growth of the population vary with the population density. There are many types of density dependent limiting factors such as; availability of food, predation, disease, and migration.

What is a dependent limiting factor?

Density-dependent factors include disease, competition, and predation. Density-dependant factors can have either a positive or a negative correlation to population size. With a positive relationship, these limiting factors increase with the size of the population and limit growth as population size increases.

How can a limiting factor affect a population’s growth?

Limiting factors include a low food supply and lack of space. Limiting factors can lower birth rates, increase death rates, or lead to emigration. Limiting factors determine the carrying capacity of a population. Recall that when there are no limiting factors, the population grows exponentially.

Is pollution a density independent factor?

Pollution. Like other density independent factors, pollution is a good example of a density independence. While humans are concentrated in cities around the globe, the emissions and chemicals we create are dispersed into the atmosphere. From here, they are carried globally and affect all organisms.

What are two assumptions of density independent models?

assumptions correspond to density independence because they imply that the per capita birth and death rates are independent of density. The rate of births is proportional to the number of individ- uals present. The rate of deaths is proportional to the number of individ- uals present.

What are three examples of density independent limiting factors?

The category of density independent limiting factors includes fires, natural disasters (earthquakes, floods, tornados), and the effects of pollution. The chances of dying from any of these limiting factors don’t depend on how many individuals are in the population.

What would the population density be if 100 ants live in an 8 sq m plot of grass?

Is weather a density dependent factor?

Density-dependent factors have varying impacts according to population size. Density-independent factors are not influenced by a species population size. All species populations in the same ecosystem will be similarly affected, regardless of population size. Factors include: weather, climate and natural disasters.

Which is most likely to be a limiting factor for plants in a rainforest biome?

What discovery led Darwin to develop his theories on adaptation a the Galapagos Islands contain a range of habitats B the Galapagos Islands originate from volcanoes C the birds Darwin found in the Galapagos were different types of finches not separate?

Answer Expert Verified. The answer to this question is c that Darwin found different types of finches not different types of birds. The discovery prompted Darwin to realize that the different types of adaptation allowed the varying types of finches to perform specific functions in their habitats.

What are three types of mimicry?

There are three forms of mimicry utilized by both predator and prey: Batesian mimicry, Muellerian mimicry, and self-mimicry. Mimicry refers to the similarities between animal species; camouflage refers to an animal species resembling an inanimate object.

What is an example of Batesian mimicry?

An example of Batesian mimicry is the poisonous coral snake and the king snake, which is the mimic. Coral snakes are quite venomous, and their bite is very dangerous to humans and other animals. King snakes, on the other hand, are harmless.

What do you mean by mimicry?

Mimicry, in biology, phenomenon characterized by the superficial resemblance of two or more organisms that are not closely related taxonomically. This resemblance confers an advantage—such as protection from predation—upon one or both organisms by which the organisms deceive the animate agent of natural selection.
