Vocabulary
The maximum number of organisms that an environment can support.
What is a CARRYING CAPACITY
A hurricane destroys a farm fields where saw grass 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. Increase
B. Decrease
C. Both increase or decrease
B. Decrease

A. Resources
B. Species
C. Boundary
D. Parasitism
A. Resources
The variety of life forms in a particular ecosystem.
What is BIODIVERSITY?
The four important resources of an ecosystem.
What is a FOOD, WATER, SHELTER and MATE?
A group of organisms of the same species that live in a certain area.
What is POPULATION?
____________ 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
What is D. All of the above?
Give two example of a human activity that can impact the carrying capacity of an ecosystem.
What is DEFORESTATION, URBANIZATION, Rampant WASTE DISPOSAL that causes FLOOD, POLLUTION

A. Increase in reproductive success
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
A Biotic or abiotic environmental factor that restricts the growth of a population.
What is a LIMITING FACTOR?
A type of limiting factor that comes into play when a population reaches a certain number of organism or size.
What is DENSITY-DEPENDENT LIMITING FACTORS?
A constant increase in the number of population resulting in a J-shaped curve
What is EXPONENTIAL GROWTH?
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
PREADATION is...
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
What is 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 have 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.
A community of organisms that live, feed and interact with the environment is called ____________.
What is ECOSYSTEM?
