Warm blooded” - organisms that use thermal energy generated by metabolism to maintain homeostatic body temperatures

“Cold blooded” - organisms that lack efficient internal mechanisms for maintaining body temperature, though they may regulate their temperature behaviorally by moving into the sun or shade or by aggregating with other individuals.

A group of individuals of the same species living in a specific geographical area at the same time, capable of interbreeding

All the living things in an area: an interacting group of various species populations (plants, animals, bacteria, fungi) that coexist and share a specific habitat or geographical area at the same time.

The living and non-living things in an area: An ecosystem is a community of living organisms (plants, animals, microbes) interacting with each other and their non-living environment (sunlight, soil, water, air) within a specific area.

a large, distinct geographical region characterized by a specific climate (temperature/precipitation), soil type, and dominant plant and animal communities adapted to that environment. Examples: tundra, desert, tropical rainforest, etc.

Organisms that capture energy from physical/chemical sources Photosynthetic organisms capture energy in sunlight; contributes to primary productivity Chemosynthetic organisms capture energy from small inorganic molecules; can occur absence of oxygen

Organisms that need to eat. They include carnivores, herbivores, omnivores, decomposers, and scavengers, metabolize carbohydrates, lipids, and proteins as sources of energy

The sustainable abundance of a species that can be supported by the ecosystem’s total available resources

Heterozygous advantage

When the heterozygous genotype has a higher relative fitness than either the homozygous dominant or homozygous recessive genotype

Ectotherm	“Cold blooded” - organisms that lack efficient internal mechanisms for maintaining body temperature, though they may regulate their temperature behaviorally by moving into the sun or shade or by aggregating with other individuals.
Population	A group of individuals of the same species living in a specific geographical area at the same time, capable of interbreeding
Community	All the living things in an area: an interacting group of various species populations (plants, animals, bacteria, fungi) that coexist and share a specific habitat or geographical area at the same time.
Ecosystem	The living and non-living things in an area: An ecosystem is a community of living organisms (plants, animals, microbes) interacting with each other and their non-living environment (sunlight, soil, water, air) within a specific area.
Biome	a large, distinct geographical region characterized by a specific climate (temperature/precipitation), soil type, and dominant plant and animal communities adapted to that environment. Examples: tundra, desert, tropical rainforest, etc.
Autotroph	Organisms that capture energy from physical/chemical sources Photosynthetic organisms capture energy in sunlight; contributes to primary productivity Chemosynthetic organisms capture energy from small inorganic molecules; can occur absence of oxygen
Heterotroph	Organisms that need to eat. They include carnivores, herbivores, omnivores, decomposers, and scavengers, metabolize carbohydrates, lipids, and proteins as sources of energy
Carrying Capacity	The sustainable abundance of a species that can be supported by the ecosystem’s total available resources
