Biology Unit 3 - Life on Earth :question:
Ecosystems
Biodiversity
The total number or species in a habitat
Species
organism who's genes are similar enough to - when bred - produce fertile offspring
Population
Group of organisms of the same species
Community
All the organisms of one species living in a biome.
Ecosystem
Geographic area where plants, animals, and other organisms, as well as the non-living counterparts
live
.
Niche
the role an organism plays in a community and how it interacts with the living and non-living counterparts in the ecosystem.
KEY
Definitions
Ecosystems
Biotic/Abiotic Factors
Photosynthesis
Biotic Factors
Disease
Competition
competition for environmental resources.
Predation
a reduction in predators can lead to an increase in prey.
Grazing
Food Availability
Abiotic Factors
pH
Measured with a pH Meter
Soil Moisture
Measured with a Moisture meter
Temperature
Measured with a thermometer
Light Intensity
Measured with a light meter
Photosynthesis
enzyme controlled reaction
CO2 + Water ----------------------> Glucose + Oxygen
Light energy
uses chlorophyll
a green pigment that can catch light energy
Intraspecific
Between organisms of the same species
More aggressive because they need the
exact
same resources
Interspecific
Between organisms of different species
