What is the term for the place where an organism lives?
A habitat is a place where an organism makes its home. A habitat meets all the environmental conditions an organism needs to survive. For an animal, that means everything it needs to find and gather food, select a mate, and successfully reproduce.
When exponential growth is plotted over time a J shaped curve emerges?
When exponential growth is plotted over time an S-shaped curve emerges. When exponential growth is plotted over time a J-shaped curve emerges. The maximum number of individuals of a population that a habitat can support indefinitely is its carrying capacity.
Which best describes the link between survivorship curves and opportunistic species?
Which best describes the link between survivorship curves and opportunistic species? Opportunistic species are limited by density-independent factors and have many offspring. Researchers studying guppies in Trinidad found that guppies in streams with high predation reproduced earlier and more frequently.
What is the difference between a community and a population quizlet?
A population is a group of organisms of the same species that live in the same area. A community is a group of different populations that live in the same area.
What place does organism?
The place where an organism lives is known as habitat. A habitat is that type of natural environment in which a particular species of an organism lives.
What is terrestrial habitat?
Terrestrial habitats are ones that are found on land, like forests, grasslands, deserts, shorelines, and wetlands. Terrestrial habitats also include man made habitats, like farms, towns, and cities, and habitats that are under the earth, like caves and mines.
Which is the characteristic shape of a curve illustrating logistic growth?
As competition increases and resources become increasingly scarce, populations reach the carrying capacity (K) of their environment, causing their growth rate to slow nearly to zero. This produces an S-shaped curve of population growth known as the logistic curve (right).
When the resources are unlimited the population Exhibit J-shaped curve?
1: When resources are unlimited, populations exhibit exponential growth, resulting in a J-shaped curve. When resources are limited, populations exhibit logistic growth.
What is the word used to describe a non mutualistic relationship between species in which one species lives in or on another species the host causing it harm?
commensalism, in biology, a relationship between individuals of two species in which one species obtains food or other benefits from the other without either harming or benefiting the latter.
What is survivorship in environmental science?
Ecologists use survivorship curves to visualize how the number of individuals in a population drops off with time. In order to measure a population, ecologists identify a cohort, which is a group of individuals of the same species, in the same population, born at the same time.
What happens to population numbers as intraspecific competition increases?
The major impact of intraspecific competition is reduced population growth rates as population density increases. When resources are infinite, intraspecific competition does not occur and populations can grow exponentially.
Do the students in your class make up a population or a community explain?
All of the students in your classroom would be an example of a population. A population can be defined as a specific species within a determined…
What is a place where an organism lives and grows?
The place where an organism lives is known as habitat. A habitat is that type of natural environment in which a particular species of an organism lives.
Why do living organisms live?
Most living things need food, water, light, temperatures within certain limits, and air. Living things have a variety of characteristics that are displayed to different degrees: they respire, move, respond to stimuli, reproduce and grow, and are dependent on their environment.
What is an arboreal habitat?
An arboreal habitat is a home for organisms that live in trees. Habitats provide critters with adequate food, shelter, and other conditions so they can thrive and reproduce.
What is another name for terrestrial habitat?
Terrestrial ecology (also known as soil ecology), the study of the interactions among soil organisms, and between biotic and abiotic aspects of the soil environment. Terrestrial ecoregion, land ecoregions, as distinct from freshwater and marine ecoregions.
How are exponential and logistic growth models similar and different?
Exponential growth is a growth in population wherein the number of individuals increases. This happens even when the rate of growth does not change. As a result, it creates an explosion of the population. Logistic growth entails exponential growth in population along with a growth rate which is in a constant state.
Which equation describe the geometric growth resulting in AJ shaped curve?
It may be summarized mathematically as: dN/dt = rN (with a definite limit on N) where N is the number of individuals in the population, t is time, and r is a constant representing the intrinsic rate of increase (biotic potential) of the organism concerned.
When resources are limited populations exhibit logistic growth in logistic growth population growth rate as resources become?
When resources are limited, populations exhibit logistic growth. In logistic growth, population expansion decreases as resources become scarce, leveling off when the carrying capacity of the environment is reached, resulting in an S-shaped curve.
What are population curve is called?
The growth of the population eventually slows nearly to zero as the population reaches the carrying capacity (K) for the environment. The result is an S-shaped curve of population growth known as the logistic curve. It is determined by the equation. carrying capacity and exponential versus logistic population growth.
When two organisms live in close association it is called?
Symbiosis: A close and long-lasting association between two or more organisms of different species.
When one organism lives inside the body of another and both benefit the relationship is called?
Key terms
| Term | Meaning |
|---|---|
| Symbiosis | Interspecific interaction in which two species live together in a long-term, intimate association |
| Mutualism | A symbiotic relationship between two species in which both partners benefit |
| Commensalism | A symbiotic relationship between two species in which one benefits and the other is unaffected |
What is life table in ecology?
A life table records matters of life and death for a population—literally! It summarizes the likelihood that organisms in a population will live, die, and/or reproduce at different stages of their lives.
What are types of survivorship?
Individuals with Type I survivorship exhibit high survivorship throughout their life cycle. Populations with Type II survivorship have a constant proportion of individuals dying over time. Populations with Type III survivorship have very high mortality at young ages.
How are company resources level of competition and population density related?
Because competition is often more intense as population size increases (and/or resources diminish) – the effect of competition is often density-dependent, that is at higher population density competition increases.
Why is interspecific competition generally less effective at limiting population size that intraspecific competition?
Interspecific competition is usually weaker because two species never use exactly the same resources (they do not have the same ecological niche).
What is the difference between population health and community health?
While the term can be broadly defined, community health tends to focus services, education and research on geographical areas with shared characteristics. Population health, meanwhile, is concerned with the distribution of health outcomes across a group of individuals.
How do density-independent limiting factors affect how a population grows?
Density-dependent limiting factors cause a population's per capita growth rate to change—typically, to drop—with increasing population density. One example is competition for limited food among members of a population. Density-independent factors affect per capita growth rate independent of population density.
What are living organisms?
A living organism is composed of cells. The cells divide and the body of the organisms show growth due to the increase in the number of cells. A tree is a living organism and shows the process of growth. Road, pen, and water are non-living organisms which do not show the process of growth.
What defines a living organism?
All living organisms share several key characteristics or functions: order, sensitivity or response to the environment, reproduction, adaptation, growth and development, homeostasis, energy processing, and evolution. When viewed together, these characteristics serve to define life.
