Succession & Biomes
This type of succession begins on bare rock with no soil.
Primary Succession
The zone where sunlight penetrates and photosynthesis occurs.
Photic Zone
A group of the same species living in one area.
Population
The maximum number of individuals an environment can support.
Carrying capacity
Variation within a species, such as a jaguar’s spots.
DOUBLE JEOPARDY - Genetic diversity
Succession that occurs when soil is already present.
Secondary Succession
The zone of water where no sunlight reaches.
Aphotic Zone
All populations living together in an ecosystem.
Community
Rapid reproduction and short lifespans describe these strategists.
r-strategists
Roads that split forests are an example of this threat
Habitat fragmentation
In this biome, evaporation exceeds precipitation.
Desert
This aquatic ecosystem has the highest biodiversity due to mixing fresh and salt water.
Estuary
The number of individuals per unit area.
Population density
Humans, with fewer offspring and long parental care, are these strategists.
K-strategists
The CITES treaty prevents the trade of these species.
Endangered species
This biome has the greatest biodiversity of all terrestrial biomes.
Tropical Rainforest
Fast-flowing rivers have fewer species because animals are not adapted to this.
Strong currents
Term that describes how individuals are spaced (clumped, uniform, random).
(DOUBLE JEOPARDY) Dispersion
A pyramid-shaped age structure shows this type of growth.
Rapid growth
Runoff that leads to algae blooms and oxygen depletion.
Eutrophication
Permafrost prevents trees from growing in this biome.
Tundra
Coral reefs thrive in this aquatic zone.
Photic Zone
Entering a population is called this; exiting a population is called this (Two answers)
Immigration and Emigration
An inverted pyramid-shaped age structure shows this type of growth.
Negative growth
Caused by burning fossil fuels, this leads to acid rain.
Sulfuric acid
