An environment that provides the things an organism needs to live, grow, and reproduce.
What is a habitat?
The four spheres of earth
What are hydrosphere, biosphere, atmosphere, and geosphere?
The niche an organism can occupy without competition
What is a fundamental niche?
Another word for producers
What is an autotroph?
The symbiotic relationship in which both organisms benefit, e.g., a clownfish and sea anemone
What is mutualism?
An organism that eats both plants and animals
What is omnivore?
The sphere that is made of all the water on earth's surface, underground, and in the air
What is hydrosphere?
The niche an organism occupies because of competition
What is the realized niche?
Another word for consumers
What is heterotroph?
This organism is an herbivore, therefore it falls in this level of a trophic pyramid
What is primary consumer?
The nonliving portion of an environment
What is abiotic?
The sphere that is made of all of the gases on earth
What is atmosphere?
Organisms that have a limited tolerance, such as a koala
What is a specialist?
Shows the transfer of energy in a food chain
What is an arrow?
Symbiotic relationship in which one organism benefits and the other is unaffected and unharmed
What is commensalism?
An organism that feeds on dead and decaying matter
What is a scavenger?
Clouds belong in this sphere
What is the hydrosphere?
Interacting populations (many species together in one place)
What is community?
Shows many overlapping, interconnected food chains
What is a food web?
Percent of energy that is NOT transferred as food and is given off as heat
What is 90%?
An organism that is at the top of an energy pyramid belongs to this trophic level
What is tertiary consumer?
The portion of the hydrosphere that is frozen
What is the cryosphere?
The levels of organization from smallest to largest (there are six)
What is organism, population, community, ecosystem, biome, biosphere?
Break down dead and decaying matter into simpler molecules that can be absorbed
What is a decomposer?
States that energy can neither be created nor destroyed
What is the First Law of Thermodynamics?
