|
Abiotic features of a habitat
|
Weather, temperature, soil features, fire, pollution, sunlight, availability of oxygen, water conditions, temperature, and so on
|
|
|
Carrying capacity
|
Term for the maximum level the population may reach at which it will continue to thrive in the given environment
|
|
|
Density-dependent factors
|
Biotic limiting factors such as population growth issues and interactions between species are also called ____________
|
|
|
Density-independent factors
|
Abiotic limiting factors are also known as these, because they do not relate to population density.
|
|
|
Population density
|
Number of individuals of a particular species living in a particular area
|
|
|
Biotic factors of a habitat
|
Availability of food, competition, predator-prey relationships, symbiosis, and overpopulation
|
|
|
Homeostasis
|
A dynamic balance achieved within an ecosystem functioning at its optimum level
|
|
|
S-curve
|
The curve expression logistic population growth that reflects limiting factors on population, where growth accelerates to a point and then slows down.
|
|
|
J-curve
|
The curve expressing exponential population growth, where there is no environmental or social limit on population size and the rate of growth accelerates over time
|
|
|
Mortality
|
Death rate
|
|
|
Limiting factors
|
Factors that determine how much a particular population within a community will be able to grow
|
|
|
Decomposers
|
Bacteria, fungi, and some animals that recycle the organic material found in dead plants and animals, back into the food chain
|
|
|
Producers
|
In the food chain, photosynthetic organisms are ___________
|
|
|
Biogeochemical
|
The system whereby the substances needed for life are recycled and transported throughout the environment
|
|
|
Niche
|
The role a species plays within the ecosystem, including its physical requirements, biological activities, and place in the food chain.
