a model that describes how water molecules move among Earth’s ecosystems and atmosphere
an interaction in a food web where one population directly affects the abundance of another
Direct Effect
Producers
When rain, snow, sleet, hail fall from clouds. This is called?
Precipitation
The process in which carbon dioxide is released into the atmosphere
Cellular Respiration
a model that describes how carbon-based molecules move among Earth’s ecosystems and atmosphere
Carbon Cycle
a kind of consumer that uses the wastes or dead remains of other organisms as a source of energy and matter
Decomposer
They are consumer at the third level of the food chain
Tertiary Consumer
When the liquid water go from the river to the soil, this is called?
Absorption
Producers use this process to make glucose from carbon dioxide, water and the sunlight energy.
Photosynthesis
a model that describes how nitrogen-based molecules move among Earth’s ecosystems and atmosphere
Nitrogen Cycle
an individual path in a food web
Food Chain
They are consumers at the top of the food chain
Top/Apex Predator
When the water molecules from the lake and soil turn into water vapor back into the atmosphere, this is called?
Evaporation
What carbon molecule is present in the breath you exhale?
Carbon Dioxide
a scientific law that states the amount of matter in a closed system stays the same, although the forms of that matter may change
Law of Conservation of Matter
a model that shows feeding relationships between organisms in an ecosystem
Food Web
What organism recycles the waste and dead organisms back to the ecosystem
Decomposer
What kind of system is Earth?
A Closed System
What form of carbon is present in plants and then is used for cellular respiration?
Glucose
the re-planting of forests that have been cut down
Reforestation
a model that shows how much energy is transferred from one stage to the next in a food chain
Trophic Pyramid
Arrow
What is one exception to the law of conservation of matter where Earth gains matter
Space objects: meteors
