Intro to Ecology
___________is the normal changes that take place when new organisms grow in an area.
Name two types of reproduction.
Sexual and Asexual
The maximum population size an environment can support.
What is carrying capacity?
One organism benefits; the other is neither helped nor harmed.
What is commensalism?
living factors in an ecosystem.
______________is made up of all organisms of the same species that live in an area.
organisms that are the first to move into an area.
What organelle processes and ships proteins?
Golgi Apparatus
What type of growth occurs when a population levels off at carrying capacity?
Logistic growth.
One organism (parasite) benefits while the host is harmed.
What is parasitism?
non-living factors in an ecosystem.
The least complex level of organization in Ecology
Species/Individual
____________is succession that begins in a place that already has soil.
Movement of molecules requiring energy (ATP).
What is active transport
Give an example of a density-independent limiting factor.
Weather, pollution, or natural disasters.
Both organisms benefit and help each other survive.
What is mutualism?
Place where an organism lives
A habitat
_____________includes all the populations animals living together in one ecosystem.
__________is the type of succession that begins in a place without plants or soil in the past.
What are the three parts of the Cell Theory?
1. All living things are made of cells. 2. Cells are the basic unit of life. 3. All cells come from pre-existing cells.
Name two factors that increase population size.
Birth (natality) and immigration.
Snake eating a frog or hawk eating a mouse.
what is predation.
________Is a stable biological community that is the end-point of ecological succession
What organelle breaks down dead material and waste?
Lysosome
Give an example of a density-dependent limiting factor.
Competition, predation, parasitism, or disease.
Lions and hyenas competing for prey.
Competition
