3.1
This is the scientific study of interactions among organisms and between organisms and their physical environment.
Ecology
These are organisms that create their own food/energy using sunlight or chemical energy
Primary Producers
A series of steps in which organisms transfer energy by eating and being eaten.
Food chain
Water vapor turns back into liquid water
Condensation
An ecosystem consists of these two factors.
Abiotic and biotic factors
This process captures light energy and uses it to power chemical reactions that convert carbon dioxide and water into oxygen and energy-rich carbohydrates.
Photosynthesis
Each step in a food chain or food web
Trophic Level
Liquid or solid water that falls from clouds
Precipitation
This is a group of ecosystems that share similar climates and typical organisms.
Biome
Consumers are also known as: ___
Heterotrophs
These organisms "recycle" dead matter that can be reused by primary producers.
Decomposers/Detritivores
Liquid water turns into water vapor from bodies of water
Evaporation
What three methods do ecologists use to study?
Observation, Experimentation, and modeling.
This consumer breaks down dead organic matter chemically
Decomposer
This pyramid shows the relative number of individual organisms at each trophic level in an ecosystem.
Pyramid of numbers
Evaporation of water from plants/plant leaves
Transpiration
List the levels of organization in order.
Individual, Population, Community, Ecosystem, Biome, Biosphere
The use of chemical energy to produce carbohydrates.
Chemosynthesis
If there are 5,000 calories at the primary producer level, how many calories are expected to be found at the secondary producer trophic level? (Hint*: That is 2 levels up.)
50 calories
Bonus: When bacteria in the soil convert nitrogen gas into ammonia.
Nitrogen Fixation
