Biodiversity
The definition of ecosystems.
What is a group of organisms that interact with each other in a certain environment?
This shows the interconnected feeding relationships between organisms in an ecosystem.
What is a food web?
A process transforms water from a liquid to a gas using energy from the sun.
What is evaporation?
This term describes the maximum number of individuals of a species that an environment can support indefinitely.
What is carrying capacity?
The difference between biotic and abiotic factors.
What are living and non-living components of an ecosystem?
The chemical process of photosynthesis.
What is H2O + CO2 _->_sunlight_->_ C6H12O6 + O2
What is a system that absorbs and stores more carbon than it releases?
What determines the carrying capacity of a certain population.
What are limiting factors?
The definition of a trophic cascade.
What is the loss of a species at a higher trophic level that has a big impact on lower trophic levels?
what mass/area measures
What is biomass
This process returns nitrogen to the atmosphere by converting nitrates to nitrogen gas.
What is denitrification?
This carbon-rich substance forms when organic matter decomposes under anaerobic conditions over millions of years.
What is fossil fuel?
The importance of biodiversity and what it refers to.
What makes ecosystems sustainable and resilient? What refers to having many different populations that can fill a certain niche?
How much energy is passed on from one trophic level to the next?
What is the 10% rule?
The form of nitrogen that can be readily absorbed and used by plants.
What is Nitrate NO3-?
The difference between detrivores and decomposers.
What consumes dead/decaying material and breaks it down internally vs. what breaks down material using enzymes externally & absorbs the nutrients?
How habitat change affects biodiversity
What is habitat loss and fragmentation making ecosystems unsustainable?
Where photosynthesis occurs.
Where is the chloroplast of plant cells and in autotrophs?
What organic compounds always contain.
What is Carbon and Hydrogen?
The difference between bioaccumulation and biomagnification.
What is the uptake and storage of a substance in one organism's tissues versus the increase in concentration of that substance as it moves up the food chain
