Carrying Capacity

largest number of individuals of a population that a environment can support

Density-Dependent

A factor that limits a population more as population density increases. For example: A disease that spreads more easily among organisms in a dense population than in a less dense population

Population

The amount of organisms of the same species living in an area

Zero Population Growth

when birth rate equals death rate

Mutualism

symbiotic relationship in which both species benefit

Autotroph

an organism that creates its own food and energy (not producer)

Omnivore

an organism that eats both plants and animals

Biomass

the total mass of living matter in an organism

Carbon Cycle

the organic circulation of carbon from the atmosphere into organisms and back again

Cellular Respiration

process that releases energy by breaking down glucose and other food molecules in the presence of oxygen creates carbon dioxide and is made in cells(Plants and Animals)

sugar + oxygen -> carbon dioxide + water

Organism

any living thing

Death Rate

the ratio of deaths in an area to the population of that area

Equilibrium

When the population has reached its carrying capacity

Competition

the struggle between organisms to survive in a habitat with limited resources

Immigration

movement of individuals into an area occupied by an existing population(INTO)

Community

a group of interdependent organisms inhabiting the same region and interacting with each other

Commensalism

the relation between two different kinds of organisms when one receives benefits from the other without damaging it

Producer

an organism that creates its own food and energy (not autotroph)

Carnivore

organism that obtains energy by eating other consumers

Food Chain

Simple Model to show how matter and energy move through an ecosystem through a specific path

Abiotic

non-living factor

Nitrogen Cycle

the circulation and reutilization of nitrogen in both inorganic and organic places.

Photosynthesis

process by which plants and some other organisms use light energy to convert water and carbon dioxide into oxygen and high-energy carbohydrates such as sugars and starches

carbon dioxide + water + sunlight -> oxygen + sugar

Prey

hunted organism or caught for food
