Ecosystem Basics & Relationships
This term describes any place on Earth where living things interact with each other and with non-living things.
What is an ecosystem?
Animals that eat only plants or plant-like organisms fall under this consumer classification.
What are herbivores?
This key process in the water cycle occurs when a liquid changes into a gas.
What is evaporation?
The introduction of a non-native species into an ecosystem (either accidentally or intentionally) is known as this.
What is bioinvasion?
The complete disappearance of a species from Earth is known by this term.
What is extinction?
These non-living components of an ecosystem include things like water, sunlight, and air.
What are abiotic factors?
Organisms that create their own food using light energy, carbon dioxide, and water are called this.
What are producers?
Matter in nature continually moves from this non-living environment to the biotic environment and back again.
What is the abiotic environment?
This type of succession takes place in a completely barren habitat with no pre-existing soil, such as on fresh lava flows or behind a melting glacier.
What is primary succession?
Species whose overall population numbers are rapidly declining are classified under this label.
What is threatened
When individuals belonging to the exact same species live together in the same defined area, they form this.
What is a population?
This percentage represents the amount of energy passed on from one level of a food chain to the next.
What is 10% (or up to 10%)?
In the carbon cycle, carbon is removed from the atmosphere by producers through this essential process.
What is photosynthesis?
This is the term for the first species to establish itself in a newly formed or barren habitat.
What is a pioneer species?
Human activities accelerate species extinction rates primarily because they alter the environment too quickly for organisms to perform this natural response.
What is adapt (or adaptation)
This type of symbiotic relationship benefits one species while leaving the other completely unharmed and unaffected.
What is commensalism?
In a food chain containing grass, a rabbit, and a fox, the rabbit serves as this type of consumer.
What is a primary consumer?
Carbon is returned back to the atmosphere as carbon dioxide in the carbon cycle in two ways. Name one of them.
What is cellular respiration (by animals/decomposers) or combustion?
This type of succession occurs in an area where a previous community was destroyed or greatly altered by events like a forest fire.
What is secondary succession?
This calculation measures a person's overall environmental impact by combining their land, water, energy, food, and waste usage.
What is an ecological footprint?
These are the 5 basic needs required by every living thing to survive.
What are water, food, energy, oxygen, and suitable living conditions?
This is the word formula/equation for cellular respiration.
What is Sugar (glucose) + Oxygen --> Carbon Dioxide + Water + Energy?
When organisms die, carbon is returned to the atmosphere as carbon dioxide when these organisms break down their bodies.
What are decomposers?
This stable, mature ecosystem community with many different species will remain steady for a long time unless disturbed.
What is a climax community?
This phenomenon occurs when toxic pollutants increase in concentration as they move up through higher levels of a food chain.
What is biomagnification?
