all organisms of the same species that live in an area at the same time
What is population?
100
an organism that uses an outside energy source like the Sun to make its own energy/food
What is a producer?
100
the features of the environment that are alive or were once alive, such as plants and animals
What are biotic factors?
100
a model that shows all the possible feeding relationships among the organisms in a community
What is a food web?
200
the study of interactions that occur among organisms and their environments
What is ecology?
200
the populations of all species living in an ecosystem
What is community?
200
an organism that gets energy/food by eating other organisms
What is a consumer?
200
the features of the environment that are nonliving or physical, such as air, water, sunlight, soil and temperature
What are abiotic factors?
200
the hunter and the hunted
What are predators and their prey?
300
all the organisms living in an area and the nonliving parts of that environment
What is an ecosystem?
300
the largest number of individuals of one species that an ecosystem can support over time
What is carrying capacity?
300
any close relationship between species
What is symbiosis? (or a symbiotic relationship)
300
the air that surrounds Earth
What is the atmosphere?
300
the largest layer of the energy pyramid
What are the producers (plants)?
400
the place in which an organism lives
What is habitat?
400
anything that restricts the number of individuals in a population
What is a limiting factor?
400
an organism's role in its environment
What is a niche?
400
a mixture of mineral and rock particles, the remains of dead organisms, water, and air
What is soil?
400
the production of energy-rich nutrient molecules from chemicals
chemosynthesis
500
this makes life on Earth possible
What is the Sun?
500
a very fast growth pattern in a population; this is because the larger a population gets, the faster it grows; continues until carrying capacity sets in
What is exponential growth?
500
DAILY DOUBLE
1. a symbiotic relationship in which both species benefit
AND
2. a symbiotic relationship in which one organism benefits and the other is not affected
What is mutualism AND commensalism?
500
the process that provides cells with the energy needed for all life processes
