Succession
the process of change in the structure of an ecological community over time. The time scale can be short decades or long millions of years.
ecological succession
Hardy species which are the first to colonize barren environments or previously biodiverse steady-state ecosystems that have been disrupted, such as by fire.
pioneer species
Two factors that contribute to the growth of a population.
birth and immigration
what is the word that is used to refer to the ecosystem that is in the water?
aquatic
the variety and variability of life on Earth. It is typically a measure of variation at the genetic, species, and ecosystem level.
biodiversity
one of two types of biological and ecological succession of plant life, occurring in an environment devoid of vegetation and other organisms usually lacking soil, such as a lava flow or area left from retreated glacier
primary succession
Among the first living things to grow on fresh rock exposed after an event such as a landslide.
lichen
Two factors that contribute to the decline of a population.
death and emigration
Where do most ocean pollutants come from?
Runoff from land
the ability to exist constantly. In the 21st century, it refers generally to the capacity for the biosphere and human civilization to coexist.
sustainability
process started by an event (e.g. forest fire, harvesting, hurricane, etc.) that reduces an already established ecosystem (e.g. a forest or a wheat field) to a smaller population of species with preexisting soil
secondary succession
a mixture of organic matter, minerals, gases, liquids, and organisms that together support life. it needs to be created during primary succession and is already available in secondary succession
soil
The maximum number of organisms an environment can support
carrying capacity
The richest biodiversity in the ocean can be found where? (rainforest of the sea)
Coral Reefs
the natural science that studies life and living organisms, including their physical structure, chemical processes, molecular interactions, physiological mechanisms, development and evolution.
Biology
An ecosystem which, through the process of ecological succession, has reached a steady state (equilibrium).
climax community
the pioneer species in secondary succession can have this structure because the soil is already present.
roots
essential resource that is in short supply or unavailable that determines carrying capacity and prevents an organism from achieving their biotic potential Can include migration, disease, food availability, mating success
limiting factor
A partially enclosed coastal body of ocean water with one or more freshwater rivers or streams flowing into it and mixing, and with a free connection to the open sea. So it is an area where a lot of organisms exist that can survive in both salt and fresh water.
estuary
the amount of salt in water and what has more salt a river or the ocean?
salinity and ocean
A branch of biology that studies the interactions among organisms and their biophysical environment, which includes both biotic and abiotic components.
ecology
pioneer species of plants and algae in both types of ecological succession play this role in the food chain.
autotroph or producer
When immigration and birth occur at lower rates than emigration and deaths, what will happen to the overall population?
decrease
name for the superficial area of the aquatic ecosystem where light penetrates and the temperature is warmer so photosynthesis occurs.
photic zone
covers more than 70% of the earths surface
oceans
