well as what you have learned during this unit.
What is the main cause of competition among organisms in an ecosystem?
(1 point)
Abundance of resources
Cooperation among species
Limited resources
Overpopulation of predators
Question 2
A) How does competition in an ecosystem primarily affect population size? (1 point)
It leads to an increase in population size.
It causes a decrease in population size.
It has no effect on population size.
It results in random fluctuations in population size.
Question 3
A) Which term best describes the competition that occurs within the same species for
limited resources? (1 point)
Intraspecific competition
Interspecific competition
Cooperation
Mutualism
Question 4
A) How does competition among organisms impact the overall biodiversity of an
ecosystem? (1 point)
It increases biodiversity by promoting the survival of the fittest.
It decreases biodiversity by causing extinction of weaker species.
It has no impact on biodiversity.
It decreased biodiversity by causing weaker species populations to increase.

Question 5
A) What is the main focus of the investigation described in the portfolio? (1 point)
Analyzing predator
prey relationships
Investigating the effects of pollution on ecosystems
Exploring the role of decomposers in nutrient cycling
Studying the impact of resource availability on animal populations
Question 6
A) How would you summarize the relationship between limited resources and competition
in an ecosystem? (1 point)
Limited resources lead to cooperation among organisms.
Competition arises due to an abundance of resources.
Organisms compete for resources such as food, water, and shelter.
Unlimited resources eliminate the need for competition.
Question 7
A) Which statement accurately describes the concept of interspecific competition? (1 point)
It involves competition between individuals of the same species.
It occurs when organisms within the same population compete for resources.
It involves competition between individuals of different species.
It has no impact on the survival of organisms in an ecosystem.
Question 8
A) How might an increase in competition among organisms affect the overall health of an
ecosystem? (1 point)
It enhances ecosystem resilience to environmental changes.
It disrupts the balance of energy flow within the ecosystem.
It promotes the establishment of keystone species.
It leads to the depletion of resources and loss of biodiversity
