• Ecosystem
• Habitat & Niches
• Population & Growth Pattern
• Carrying Capacity
• Limiting Factors
What is Ecosystem
An ecosystem is a large community of living organisms (plants, animals and microbes) in a
particular area. Ecosystems are of any size, but usually they are in particular places.
A lake could be considered an ecosystem.
Habitat and Niches
• Every organism has a habitat and a niche.
• A habitat is all aspects of the area in which an organism lives.
• An ecological niche includes all of the factors that a species needs to survive, stay
healthy, and reproduce.
Population & Growth Pattern
• Populations grow in predictable patterns.
• The size of a population is always changing.
• Four factors affect the size of a population.
• immigration
• births
• emigration
• deaths
Population growth is based on available resources.
• Exponential growth is a rapid population increase due to an abundance of resources.
• Logistic growth is due to a population facing limited resources.
Carrying Capacity
• Carrying capacity is the maximum number of individuals of a species that an ecosystem
can support.
(Or)
• Carrying capacity = maximum number of organisms that can live somewhere, based on
the Food , water and free Space.
Carrying capacity graph
• We can read a carrying capacity graph to predict changes in population size
• Below carrying capacity = increase
• Above carrying capacity = decrease
• Over time, population stabilizes at
carrying capacity

Limiting Factors
• A limiting factor is an environmental factor that causes a population to stop growing.
• A limiting factor is an abiotic or biotic factor that restricts the number of individuals in a
population.
Abiotic Factor
• The physical components of an ecosystem.
• Any nonliving part of the environment.
Biotic Factor
• The biological influences on organisms.
• Any living part of the environment with which an organism may interact.
Abiotic Factors that influence carrying
capacity
• Temperature
• Precipitation
• Soil composition
• pH
• Humidity
• Salinity
• Amount of sunlight
• Availability of nitrogen
Biotic Factors that influence carrying
capacity
• All biological aspects of an ecosystem fall into this category.
• Vegetation composition often determines what species will be attracted to a given area
due to food availability.
• Scientists note that competition, predator-prey relations, mutualism, and host-pathogen
interactions are critical to consider when accessing carrying capacity.
