What is most likely to be a limiting factor for growth on the floor of a tropical rainforest?
Which is most likely to be a limiting factor for plants in a rainforest biome?
Which of the following would be considered a limited resource in the lower depths of the ocean?
Answer Expert Verified. The correct answer is B. Sunlight is a limited resource in the lower depths of the oceans. A is not correct, as there is plenty of water throughout the entire ocean.
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.
