Predation & Competition
This type of competition occurs between individuals of the same species.
What is intraspecies competition?
This type of symbiotic relationship benefits both species involved.
This type of symbiotic relationship benefits both species involved.
The organisms that produce their own food through photosynthesis or chemosynthesis.
What are primary producers?
Asexual reproduction creates offspring that are ______ to the parent.
What is genetically identical?
The difference between biotic and abiotic factors.
What is biotic factors are living, and abiotic factors are non-living?
When two different species compete for the same resource, it's called this.
What is interspecies competition?
A flea on a dog is an example of this symbiotic relationship.
What is parasitism?
The rule that states only 10% of energy is transferred from one trophic level to the next.
What is the 10% rule?
This type of reproduction combines genetic material from two parents.
What is sexual reproduction?
A species that has a disproportionately large impact on its ecosystem.
What is a keystone species?
This principle states that one species will outcompete another, potentially eliminating it from the habitat.
What is competitive exclusion?
This symbiotic relationship benefits one species while the other is unaffected.
What is commensalism?
Organisms that break down dead material and return nutrients to the ecosystem.
What are decomposers?
An organism that reproduces by splitting into two identical daughter cells does so through this process.
What is binary fission?
The role an organism plays in its environment.
What is an ecological niche?
This term describes the evolutionary adaptation that allows species to divide resources to minimize competition.
What is resource partitioning?
This type of indirect interaction occurs when a third species influences the relationship between two others.
What is indirect interaction?
The level of consumers that eat primary consumers.
What are secondary consumers?
The main advantage of sexual reproduction.
What is genetic diversity?
This process allows multiple species to coexist by using resources in different ways.
What is resource partitioning?
Give an example of a predator-prey relationship in nature.
What is an owl catching a mouse?
Explain why parasites usually do not want to kill their hosts.
What is they rely on the host for survival and nutrition?
Explain why there are so few trophic levels in a food web.
What is energy loss at each level limits how many levels can exist?
Name one reproductive strategy that combines both sexual and asexual reproduction.
What is parthenogenesis?
Explain why an increase in biodiversity benefits an ecosystem.
What is it increases resilience and stability in the ecosystem?
