Relationships in Ecosystems

What are abiotic factors?

• Living components of an ecosystem

• The nonliving chemical and physical parts of an ecosystem that affect living organisms and their environment.

• Only the water and air in an ecosystem

• The interactions between different species in an ecosystem.

What is Parasitism?

• A symbiotic relationship where one organism, the parasite, lives on or in another organism, the host, causing it harm.

• A mutual relationship where both organisms benefit from each other.

• A relationship where one organism benefits while the other is unaffected.

• A relationship where both organisms are harmed.

Exponential Growth

• A growth pattern where the rate of population increase accelerates over time, occurring under ideal, unlimited conditions.

• A steady increase in population size over time, regardless of environmental factors.

• A decline in population size due to limited resources and competition.

• A random fluctuation in population size with no clear trend.

What is Logistic Growth?

• A growth pattern where population increases exponentially without limits.

• A growth pattern where population increase slows and then stops, leveling off at the environment's carrying capacity.

• A growth pattern characterized by a sudden decline in population.

• A growth pattern that occurs only in aquatic environments.

What are Biotic Factors?

• The non-living parts of an ecosystem, such as rocks and water.

• The living or once-living parts of an ecosystem, including all plants, animals, fungi, and microorganisms.

• The chemical substances that affect living organisms in an ecosystem.

• The physical environment in which organisms live.

What is Emigration?

• The process of individuals moving out of a population's range, decreasing the population size.

• The process of individuals moving into a population's range, increasing the population size.

• The process of individuals remaining in a population's range, maintaining the population size.

• The process of individuals reproducing within a population, increasing the genetic diversity.

What is a community in an ecological context?

• An interacting group of various species in a common location, representing the living part of an ecosystem.

• A group of organisms of the same species living in a specific area.

• The physical environment where organisms live and interact.

• A collection of non-living elements in an ecosystem.

What is a Density-Independent Factor?

• A limiting factor that affects a population's size regardless of its density, such as weather or natural disasters.

• A factor that limits population growth based on the density of the population.

• A factor that only affects populations in urban areas.

• A factor that increases population size regardless of environmental conditions.

What is Mutualism?

• A symbiotic relationship where one species benefits at the expense of another.

• A symbiotic relationship between two different species where both individuals derive a fitness benefit from the interaction.

• A relationship where two species compete for the same resources.

• A relationship where one species lives inside another without causing harm.

What is a Limiting Factor?

• An environmental condition or resource that restricts the size or growth of a population in an ecosystem.

• A factor that enhances the growth of a population in an ecosystem.

• A type of predator that controls the population of prey species.

• A resource that is abundant and supports unlimited growth.
