The branch of biology dealing with the interactions among organisms and their environment:
What is ecology
100
The algae at the beginning of some aquatic food chains are this type of eater:
What are autotrophs (or primary producers)
100
These organisms feed on the remains of organic matter, releasing nutrients back into the collective life cycle:
What are decomposers
100
This refers to the parts of the earth that SUPPORT LIFE
What is the biosphere
100
This is the gaseous form of carbon released during combustion and respiration
What is carbon dioxide
200
Collectively, interacting populations of different types of species in the same ecosystem are called this:
What are communities
200
This is the primary mechanism by which most primary producers make their own food:
What is photosynthesis
200
This term refers to nonliving things within an ecosystem:
What are abiotic factors
200
This term refers to organisms that cannot produce their own source of sugars, but that eat both plants and animals:
What are omnivores
300
Collectively, a collection of individual organisms of the same species in the same space is called this:
What is a population
300
From the following list, which is NOT an abiotic factor?
plant life
soil type
rainfall
temperature
What is PLANT LIFE!
300
These types of eaters feed exclusively on animal products:
What are carnivores
400
This refers to the lowest level of environmental complexity that includes living and nonliving factors:
What is an ecosystem
400
This term refers to living things with an ecosystem:
What are biotic factors
400
In the following food chain, what level of eater is the snake:
Plant >> Insect >> Rodent >> Snake >> Hawk
What is a "tertiary," or third-level consumer
400
These types of organisms feed on the already-dead carcasses of organisms that have been predated on by other organisms, or that died from other causes:
What are scavengers
500
This refers to the "type of eater" that plants are:
What are primary producers
500
This term includes carnivores, omnivores, scavengers and decomposers:
What are consumers (or heterotrophs)
500
This refers to a series of interacting food chains:
What is a food web
500
These organisms are the base of all ecological pyramids:
What are producers (primary producers)
500
This refers to the exchange of carbon atoms between the atmosphere and the hydro & lithosphere:
