Nutrition
This type of organism feeds by secreting digestive enzymes onto dead material and absorbing the nutrients.
What is a saprotroph?
Energy is lost between trophic levels in this form.
What is heat?
Examples of this term include coal, oil, and natural gases.
What are fossil fuels?
This term is the process of burning fossils fuels, which contributes to global warming.
What is combustion?
This material forms in waterlogged soils when organic matter does not fully decompose.
What is peat?
This type of organisms ingests and feed on dead matter.
What are detritivores?
This type of relationship occurs when both species benefit from each other.
What is mutualism?
These types of gases prevent radiation (long waves) on Earth from escaping into space.
Greenhouse Gases
The adverse effect of increased CO2 concentration in the ocean, leading to reduced enzyme activity in marine organisms, is primarily due to changes (the lowering) of this factor.
What is pH?
The sun releases this type of radiation.
What is short-wave radiation?
This type of organism obtains nutrients from other carbon sources.
What is a heterotroph?
This is the variety of life in all its forms, levels, and combinations.
What is biodiversity?
This greenhouse gas has the shortest lifespan but is still a potent contributor to global warming.
What is methane?
This historic period of increased fossil fuel use has significantly raised atmospheric CO2 levels, contributing to global warming.
What is the Industrial Revolution?
This is the reason why temperature trends should be analyzed over many years.
What are seasonal changes OR long-term changes?
These type of organisms are heterotrophic and obtain nutrients from dead organisms by external digestion.
What are fungi (saprotroph)?
In an energy pyramid, this trophic level loses the most energy in an ecosystem.
What are autotrophs/producers?
This process is the primary way oceans act as carbon sinks, absorbing CO2 from the atmosphere.
What is photosynthesis?
This gas is the most abundant greenhouse gas and contributes the most to climate change.
What is carbon dioxide?
Increased CO2 in oceans results in a decline in the ability of these organisms to form their calcium carbonate skeletons.
What are corals?
This type of organism can receive energy via photosynthesis AND ingestion.
What are mixotrophic organisms?
This type of interaction occurs when a species secretes a chemical that inhibits the growth or respiration of other species.
What is allelopathy?
Along with carbon dioxide, this gas has the most significant contribution to global warming.
What is water?
Greenhouse gases contribute to global warming by preventing this type of radiation from escaping the Earth.
What is longwave radiation?
Rising global temperatures can affect this characteristic of oceans.
What are ocean currents/weather patterns?
