What is mutualism
Interaction between two or more species, fish.
What shaped curve will a graph showing exponential growth be
J -shaped curve.
What are the 2 possible outcomes of competition that we discussed
Looser could be kicked out of habitat, dividing the resources.
What is an example of density-independent population regulation
Natural disasters like forest fires.
What is parasitism
One organism lives in or on another organism, a worm.
What does abiotic mean
Physical other than biological.
What is density-dependent population regulation
Population growth rates are regulated by density.
What does biotic mean
Relating to living things.
What shaped curve with a graph showing logistic growth be
S-shaped curve.
What is biodiversity
A biological variety and variable of life.
What is a population
A group of individual organisms that live together.
What is a niche
A match of species to a specific environmental condition.
What is predation
A predator and Prey, Fox and Rabbit.
Why is a fundamental niche different from a realized niche
A realized niche is an actual environment where the species lives.
What is a community
A social unit.
What is a keystone species
A species an ecosystem heavily depends on.
What is commensalism
An association of two or more species, Rhinos and birds.
What is density-independent population regulation
Any force that affects a population.
What are two things that will cause a population's growth to INCREASE
Birth rates, and the amount of food.
How can predation help increase biodiversity
By preying and competitive dominants.
What is an example of density-dependent population regulation
Competition for food.
What is logistic population growth
Competition increases and resources become scarce.
What is herbivory
Consumption of plant materials, like Deer.
What are two things that will cause a population's growth to DECREASE
Death rates, and the amount of food.
Under what conditions does exponential growth typically happen
Few individual growths and plentiful resources.
What factors determine the carrying capacity of a habitat
Food and water availability.
How can predation affect competition
High predation can make a species sensitive to even a small amount of competition.
What is exponential population growth
The growth rate stays the same regardless of population growth.
What is carrying capacity
The number of people or living organisms without environmental degradation.
What is coevolution
Two or more species help each other out.
