How does commensalism differ from mutualism and parasitism?

• Commensalism benefits one organism, mutualism benefits both, and parasitism benefits one at the expense of the other.
• Mutualism benefits one organism at the expense of the other
• Parasitism benefits both organisms
• Commensalism benefits both organisms equally

What is resource partitioning?

• Resource partitioning is the process where different species divide a limited resource, such as food, in order to avoid competition and coexist in an ecosystem.
• Resource partitioning is the process where species compete for resources in an ecosystem.
• Resource partitioning involves species sharing the same resource without any competition.
• Resource partitioning is the process where species work together to monopolize a resource in an ecosystem.

What is character displacement?

• Character displacement is when species evolve to become more similar in traits.
• Character displacement is when species evolve to occupy the same niche.
• Character displacement is when similar species that occupy the same geographic area evolve differences in traits to reduce competition for resources.
• Character displacement is when species evolve to increase competition for resources.

How are resource partitioning and character displacement related?

• Resource partitioning and character displacement have no relationship
• Resource partitioning and character displacement are related as they both involve reducing competition by dividing resources among species.
• Resource partitioning leads to increased competition among species
• Character displacement involves sharing resources equally among species

What is the difference between a fundamental niche and a realized niche?

• The fundamental niche is the actual range, while the realized niche is the potential range.
• The fundamental niche is static, while the realized niche is dynamic.
• The fundamental niche is the potential range, while the realized niche is the actual range.
• The fundamental niche is determined by biotic factors, while the realized niche is determined by abiotic factors.

What is competitive exclusion?

• The elimination of one species by another due to competition for the same resources.
• The process of natural selection leading to the survival of the fittest
• The collaboration of two species for mutual benefit
• The coexistence of multiple species in an ecosystem without competition

How are resource partitioning and character displacement different in allopatric organisms vs. sympatric organisms?

• Resource partitioning is more common in sympatric organisms, while character displacement can occur in both allopatric and sympatric organisms.
• Resource partitioning and character displacement are both exclusive to allopatric organisms.
• Resource partitioning is a form of character displacement in sympatric organisms.
• Resource partitioning can occur in both allopatric and sympatric organisms, while character displacement is more common in sympatric organisms.

What are the different types of symbiotic relationships?

• Predation
• Cooperation
• Neutralism
• Mutualism, Commensalism, Parasitism

How would you be able to determine an organisms fundamental niche vs. its realized niche?

• Comparing the size of the organism in its fundamental niche vs. realized niche
• Observing the color variations between the fundamental niche and realized niche
• Measuring the distance the organism can travel in its fundamental niche compared to its realized niche
• Compare the range of environmental conditions where the organism could potentially survive and reproduce (fundamental niche) with where it actually exists in nature, considering biotic and abiotic factors (realized niche).

What is a keystone species?

• A keystone species is a species that has a disproportionately large effect on its environment relative to its abundance.
• A keystone species is a species that is only found in captivity.
• A keystone species is a species that has no impact on its environment.
• A keystone species is a species that is the most abundant in an ecosystem.
