20 Questions
What factor directly contributes to a reduction in cattle carrying capacity in a region due to overgrazing?
Less grass to eat
In which type of dispersion pattern do organisms exist in clusters or clumps, living in close proximity to one another?
Clumped dispersion
What causes uniform dispersion in populations?
Intraspecific competition
Why do organisms in a rainforest tend to exhibit random dispersion?
As a result of ample resources and little competition
What type of movement occurs when populations of organisms periodically move, usually motivated by the availability of resources such as food?
Migration
What does carrying capacity refer to?
The maximum number of organisms in an ecosystem
What resources affect carrying capacity?
Food, water, and shelter
When does a species reach population equilibrium?
When there is no population growth or decline
What happens to the population growth rate when carrying capacity is reached?
It decreases
How can the carrying capacity be calculated?
$K = r * N * CP$
What is the relationship between a species' carrying capacity and its population equilibrium?
They are positively correlated
How does the population growth rate change when an ecosystem reaches carrying capacity?
It decreases
What is the defining feature of exponential growth in a population?
Continued increase in growth rate
How does the carrying capacity of an ecosystem change over time?
It can change depending on available resources
What does a carrying capacity graph show when it reaches the carrying capacity?
Population growth rate decreases
What is the main reason why a region's cattle carrying capacity is reduced when cattle overgraze in that region?
Decrease in the availability of nutrients
Which dispersion pattern typically arises as a result of intraspecific competition, where members of the same species compete for necessary resources?
Uniform dispersion
Why do organisms in clumped dispersion patterns gather around places where resources are available?
Because resources are concentrated in those areas
What type of dispersion pattern is likely to occur when organisms have ample resources and very little competition within their habitat?
Random dispersion
How does migration impact the carrying capacity of populations when organisms move seasonally?
Increases the carrying capacity
Learn about carrying capacity in ecology, which refers to the maximum number of organisms of a species that can survive in a particular environment. Explore how resources like food, water, and shelter influence an ecosystem's carrying capacity and population equilibrium.
