Succession
the process of change in the species structure of an ecological community over time. The time scale can be decades (for example, after a wildfire), or even millions of years after a mass extinction.
What is ecological succession?
contamination of something
pollution
A natural resource that once we use is essentially gone, because it takes so long for it to rejuvenate itself. (ex. fossil fuels)
non renewable resources
the first species to colonize an environment
What are pioneer species?
water and human wastes that are washed down sinks, toilets, and showers.
sewage
the gradual growth of a completely destroyed ecosystem over a longer period of time.
What is primary succession?
a very dangerous heavy colorless odorless atmospheric gas
What is monoxide?
Energy that comes from heat deep within the earth.
geothermal energy
Keystone Species
this type of pollution makes sea turtles confused which way to go
light pollution
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
What is secondary succession?
Humans smoke, cars and factories throw smoke and carbon dioxide and makes it hard to breathe is what type of pollution?
air pollution
Name three natural renewable resources we can use for energy
Sun, Wind, Water, Geothermal
the ability of ecosystems to remain healthy, productive, and diverse over time
What is ecological stability/sustainability?
this type of pollution is collected on islands and usually overflows into oceans causing another type of pollution (2 answers)
land pollution, marine pollution
An ecosystem which, through the process of ecological succession, has reached a steady state (equilibrium).
What is a ecological stability?
plastic, factories, oil spills and nurdles are all a cause of what type of pollution?
water pollution
What are Gasoline, Natural Gas, Coal, Oil examples of?
fossil fuels
a mixture of fog and smoke or other pollutants
smog
Something that comes from the earth and is made into something useful for humans.
what is a natural resource
the study of the relations of organisms to one another and to their physical surroundings.
What is ecology?
emissions
What are fossil Fuels made from?
Dead plant and animal material burried, compacted and changed over many millions of years.
rain that contains acid
acid rain
Heat and Light energy that is derived from the sun
solar energy
