What is carrying capacity in the context of an ecosystem?
Carrying capacity is the maximum number of individuals of a species that an environment can sustainably support.
A hurricane destroys the bayou where sawgrass grows, which many insects eat. How would the decrease in food and space impact carrying capacity?
It would decrease carrying capacity because there wouldn't be enough food.
A forest gains a new type of plant that is nutritious for herbivores, the carrying capacity of herbivores is going to
A. Increase
B. Decrease
C. Both increase or decrease
B. Decrease
All organisms consume/ use "________" to be able to survive.
A. Resources
B. Species
C. Boundary
D. Parasitism
A. Resources
What does "interdependent relationship" mean ? Give an example
A relationship in which two organisms are mutually dependent on one another to survive.
Name two factors that can affect the carrying capacity of an ecosystem.
Food and resource availability, space, predation, disease and etc...
How have humans been efficient in increasing their carrying capacity from the estimated 1 billion to over 7 billion people?
They have become more efficient in producing and replenishing food sources
____________ are biotic or abiotic environmental conditions that limit population growth in an ecosystem.
A. Resources
B. Competition
C. Limiting Factor
D. Parasitism
C. Limiting Factor
An increase in "competition" will lead to a decrease in
A. Population size
B. Resouces
C. Reproduction rates
D. All of the above
D. All of the above
Give an example of a human activity that can impact the carrying capacity of an ecosystem.
Deforestation is a human activity that can reduce the carrying capacity of an ecosystem by decreasing habitat and resource availability.
Which of the following factors would most accurately be placed in the same side of the concept map as “Increase in population of competitors”?
A. Increase in reproductive success
B. Decrease in available living space
C. Increase in availability of freshwater
D. Decrease in population of predators
B. Decrease in available living space
1. The carrying capacity of an ecosystem is the maximum number of individuals of a species that the environment can support without causing long-term harm. This number is determined by the availability of _______.
A) Cars and roads
B) Resources like food, water, and shelter
C) Predators and prey
D) Soil and rocks
B) Resources like food, water, and shelter
What is a "Limiting Factor" ?
A Biotic or abiotic environmental factor that restricts the growth of a population.
Which are examples of human activities that can impact the carrying capacity of an ecosystem?
Urbanization, deforestation, pollution, climate change, overhunting and etc.
How do interdependent factors—such as climate and lack of resources—impact the carrying capacity of an ecosystem?
Lack of water or drastic climate changes could reduce the producers in the ecosystem, impacting all other organisms in the ecosystem. It would likely decrease the carrying capacity.
An example of a factor that can reduce an ecosystem's carrying capacity is _______.
A) An increase in resource availability
B) Habitat destruction
C) A decrease in predation
D) Migration
B) Habitat destruction
What is "Predation"?
A. species that, if removed from an ecosystem, would cause a major change in that ecosystem
B. The ecological role played by an organism
C. An interaction between organisms in which one organism captures and consumes another organism
D. None of the above
C. An interaction between organisms in which one organism captures and consumes another organism
Explain how predation can be a positive benefit to a population of prey organisms.
Predation can be a positive benefit to a population of prey because it tends to keep them below their carrying capacity.
What might happen if a population exceeds its carrying capacity?
A. Increase resources
B. Population increase
C. Resource depletion
D. Both A and B
C. If a population exceeds its carrying capacity, it may lead to resource depletion, habitat destruction, and ultimately a population decline.
An example of a factor that can reduce an ecosystem's carrying capacity is _______.
A) An increase in resource availability
B) Habitat destruction
C) A decrease in predation
D) Migration
B) Habitat destruction
