Characteristics of Life
Ecological Pyramids
Cycling of Matter
100
The study of how living things interact with the environment, or the study of life.
What is biology
100
Organisms that cannot make their own food and must feed on other organisms for energy and nutrients.
What is an herbivore
100
The production of offspring.
What is reproducing
100
The total mass of living matter at each trophic level.
What is biomass
100
the cycle of processes by which water circulates between the earth's oceans, atmosphere, and land, involving precipitation as rain and snow, drainage in streams and rivers, and return to the atmosphere by evaporation and transpiration.
What is the water cycle
200
Anything that has once had all the characteristics of life.
What is an organism
200
The total mass or weight of all living matter in a given area.
What is biomass
200
The addition of mass to an organism, and the process of natural changes that take place during the life of an organism.
What is growing and developing
200
Each level represents the amount of energy that is available to that trophic level.
What is the pyramid of energy
200
a hierarchical series of organisms each dependent on the next as a source of food.
What is the food chain
300
To gather information and answer questions.
What is a scientific method
300
The close relationship that exist when two or more species live together.
What is symbiosis
300
When an organism adapts to its environment to survive better.
What is evolving over time
300
Each level of the pyramid represents the amount of biomass consumed by the level above it.
What is the pyramid of biomass
300
the biogeochemical cycle that describes the movement of phosphorus through the lithosphere, hydrosphere, and biosphere.
What is the phosphorus cycle
400
The tested factor and it might affect the outcome of an experiment.
What is an independent variable
400
Organisms in the soil convert ammonia into nitrogen compounds that can be used by plants.
What is denitrification
400
Anything that is part of either the environment, causes a reaction, and the organism react.
What is responding to stimuli
400
A model that ecologist use to show how energy flows in through an ecosystem.
What is an ecological pyramid
400
the series of processes by which nitrogen and its compounds are interconverted in the environment and in living organisms, including nitrogen fixation and decomposition.
What is the nitrogen cycle
500
Regulation of an organisms internal conditions to maintain life.
What is homeostasis
500
The position an organism occupies in a food chain.
What is trophic level
500
They are arranged in an orderly way.
What is displaying organization
500
Each level represents the number go individual consumed by the level above it.
What is the pyramid of numbers
500
the process by which oxygen released into the atmosphere by photosynthetic organisms is taken up by aerobic organisms while the carbon dioxide released as a by-product of repiration is taken up for photosynthesis. Origin of oxygen cycle Expand.
What is the carbon and oxygen cycle
