This term refers to the natural environment where a particular species lives and grows.
What is habitat?
A limit to the number of organisms an ecosystem can support
What is carrying capacity?
The process by which a population increases in size when birth rates exceed death rates.
What is population growth?
This is the where two organisms live together in an interdependent relationship
What is symbiosis? (symbiotic relationship)
The set of environmental conditions a species can live in comfortably before experiencing stress or death.
What is tolerance range?
The gradual process by which ecosystems change and develop over time, starting from bare rock or soil.
What is ecological succession?
This is an organism’s role or position in a particular environment.
What is niche?
A small, specific location within a larger habitat, such as under a log or within a patch of moss, is called this.
What is microhabitat?
A hurricane, a flood, a storm, and a forest fire are all examples of a ___________ _______________ factor
The type of population growth seen when a population's growth slows as it approaches the environment's carrying capacity.
What is logistic growth?
In this type of symbiotic relationship, one organism is harmed while the other benefits, such as a varroa mite and a bee. The mites get into the hive through a worker bee and lay eggs. Their newly hatched mites feed on other bees' blood.
What is a parasite?
The part of the tolerance range where the organism thrives and reproduces best.
What is the optimum range?
The type of succession that occurs after a disturbance such as a forest fire or hurricane, where soil is already present.
What is secondary succession?
This species has a disproportionately large impact on its ecosystem relative to its abundance, often maintaining the structure and balance of the community.
What is a keystone species?
This is the name for the community of microorganisms that live on and inside a living organism, especially in the gut.
What is microbiome?
Diseases are ___________ _____________, therefore they have (more/less) impact on a large population.
What is density dependent and more?
This is the difference between emigration and immigration.
What is it when the population decreases in size because individuals leave the area versus when the population increases in size because individuals move to the area?
In this symbiotic relationship between birds and trees, birds may build nests in trees.
What is commensalism?
This describes the area where organisms cannot survive conditions outside of their range of tolerance
Zone of intolerance
These pioneer species play a crucial role in this early stage of primary succession by breaking down rock into soil.
What are lichen and mosses? (or lichen and algae)
This interaction occurs when herbivores consume plant material, influencing plant population and growth.
What is herbivory?
These are the three ways a population is distributed.
What is random, clumped, and uniform?
Under ideal conditions with unlimited resources, a .population will grow like this
What is exponential growth/exponentially?
This can occur if the carrying capacity of a species falls too low.
What is extinction?
In this symbiotic relationship between ants and aphids, ants protect the aphids from predators, and in return, aphids provide the ants with honeydew.
What is mutualism?
This term describes when organisms experience stress and reduced fitness due to living at the extremes of their tolerance range.
What is the zone of physiological stress?
This is an example of an event that would result in primary succession.
What is volcanic eruption, glacial erosion, and/or paved lots?
The process by which species divide resources in order to reduce competition in an ecosystem.
What is resource partitioning?
An example of this is that it can be as small as a bacterial colony inhabiting a rotting pumpkin or as large as covering most of the continent as with the Whitetail deer.
What is geographic range?
This point on a logistic growth curve represents where population growth levels off as resources become limited.
What is carrying capacity?
This type of species, when introduced to a new environment, can reduce the resources available to native species, and has this affect on the carrying capacity of the ecosystem.
What is invasive species and lowering the carrying capacity?
Explain how the introduction of an invasive species could disrupt existing mutualistic relationships in an ecosystem, and predict a possible long-term outcome.
What is the invasive species outcompeting a mutualistic partner, leading to the collapse of the mutualistic relationship and a potential decline in biodiversity?
Based on the graph, in this limit, the water is too hot for any of the organisms.
What is the higher limit of tolerance?
Compare primary and secondary succession, focusing on how each begins and the rate at which ecosystems recover.
What is that primary succession starts from bare rock and takes longer, while secondary succession begins with soil and occurs more quickly
This principle states that two species competing for the same resources cannot coexist indefinitely; one will outcompete the other.
What is competitive exclusion principle?
