Ecological Succesion
A group of populations of different organisms that live and interact in the same area.
What is an Ecological Community?
This biome has very cold temperatures, little rainfall, and a layer of permanently frozen subsoil called permafrost.
What is the Tundra?
Rivers, streams, lakes, ponds, estuaries, and wetlands are all examples of
Freshwater Ecosystem
a group of interacting populations that occupy the same area at the same time
What is a Community?
photic zone, aphitc zone, benthic zone, abyssal zone, pelagic zone
Examples of ocean zones
The establishment of a community in an area of exposed rock that does not have any top soil.
What is Primary Succession
You’d find dense evergreen trees and long winters in this northern forest biome that does not contain permafrost.
What is the Boreal Forest (or Taiga)?
This shallow, sunlight-filled zone of a lake or pond is home to many producers and consumers.
What is the littoral zone?
there is the littoral zone, limnetic, and profundal
What are Lake Zones?
Where colorful creatures and organisms live as a community(Most well known is near Australia)
What is a coral reef?
The stable, mature community that results when there is little change in the composition of species.
What is a Climax Community?
In this biome, trees that abandon their leaves each year help create the rich soil that supports them—an adaptation made necessary by a climate that refuses to stick to just one season.
What is the Temperate Forest?
These two freshwater ecosystems both contain standing water, but one is typically larger and deeper than the other.
What are lakes and ponds?
This type of ecological recovery occurs after a major disturbance that leaves soil and some organisms intact, making it a later-stage follow-up to primary and secondary succession.
What is Tertiary Succession?
Species in these ecosystems must tolerate constantly changing salinity levels due to tides mixing freshwater and saltwater together.
What are estuaries?
After a major disturbance like a wildfire or hurricane, this type of succession occurs when an ecosystem rebuilds using the soil that remains.
What is Secondary Succession
Although its soil could easily host a forest, this biome stays treeless thanks to both thirsty summers and hungry herds that keep would-be saplings in check.
What is the Temperate Grassland?
Organisms in this deep freshwater zone must tolerate low temperatures, minimal oxygen, and near-total darkness—conditions that sharply limit species diversity.
What is the profundal zone?
Bare rock, linchens, mosses, herbs, and weeds.
What are Pioneer Species?
This deep-ocean region, located below the aphotic zone and often exceeding depths of 4,000 meters, supports organisms that rely on chemosynthetic bacteria near hydrothermal vents, making it one of the few ecosystems on Earth not driven by sunlight.
What is the abyssal zone?
In ecological succession, this process occurs when earlier species modify the environment in a way that makes conditions more suitable for later species—an example being nitrogen-fixing plants enriching the soil.
What is Facilitation?
Here, the ground’s reddish hue hints at high iron levels, but its poor fertility contrasts sharply with its status as the land biome boasting the most species—helped along by constant warmth and near-daily rain.
What is the Tropical Rainforest?
This part of a lake is NOT the shore, NOT the bottom, but the big mysterious area in the middle where sunlight still reaches and tiny organisms.
What is the limnetic zone?
On bare rock left behind by a retreating glacier, this ecological process begins when pioneer species like lichens start creating soil.
What is primary succession?
The "in-between" water that causes many unusual environmental effects.
What is brackish water?
