an organism that makes its own food
autotroph, producer
symbiotic relationship where one benefits and the other is unaffected
commensalism
an organism that is killed and eaten by another organism
prey
eats tertiary (3rd level) consumers
quartenary consumer or 4th level consumer
an animal that eats both plants and animals
omnivore
an organism that is incapable of photosynthesis and must obtain its energy by consuming other organisms
consumer or heterotroph
The branch of biology that deals with relations of organisms to one another and to their physical surroundings
ecology
symbiotic relationship where one benefits and one is harmed
parasitism
a community of roganisms and their abiotic environment
ecosystem
process that all organisms undergo that releases energy from food
cellular respiration
How are autotrophs different from heterotrophs?
autotrophs make their own food from sunlight using photosynthesis and heterotrophs must eat food
organism, especially a soil bacterium, fungus or invertebrate, that breaks down dead organisms and returns nutrients back to the soil
decomposer
a consumer that eats only plants
herbivore
a series of steps in which organisms transfer energy by eating and being eaten
food chain
an organisms role and place in an environment; a specific organism's duties
niche
a group of individuals of the same species thatlive in the same area
population
a system of interlocking and independent food chains
food web
deals with the whole array of interacting species in a community- all the organisms in an area
community
a place where or location where an organism lives, has shelter, food and water
habitat
an organism that eats secondary (2nd level) consumers
tertiary consumer, carnivore, 3rd level consumer
any living thing
organism
process of turning the sun's energy, water and carbon dioxide into sugars by plants, algae and some bacteria
photosynthesis
a consumer that eats only animals
carnivore
something that eats producers
primary consumer, herbivore or 1st level consumer
obtain energy by eating primary (1st order) consumers
secondary consumers, carnivore, 2nd level consumer
What is cellular respiration?
The process of converting glucose and oxygen into energy that an organism can use
What are the products of photosynthesis? (What does photosynthesis produce?)
Oxygen and glucose
symbiosis where both organisms benefit
mutualism
