An ecosystem is comprised of these living and non-living "factors"
What are biotic and abiotic?
100
These are the world's least common type of ecosystem, comprising only 1.8% of the Earth's surface.
What are Freshwater Ecosystems?
100
When a part of a forest ecosystem is destroyed, the ground is eventually populated with grasses, followed by bushes and shrubs, and later mature trees in a process called __________________.
What is succession?
100
This is the linear sequence of organisms through which nutrients and energy pass as one organism eats another.
What is the food chain?
100
Photosynthetic and chemosynthetic organisms that make their own food are known as _______________.
What are autotrophs?
200
When evaporation from plants happens, it is called this...
What is transpiration?
200
These ecosystems are the most common, comprising 75% of Earth's surface.
What are Marine Ecosystems?
200
When the dynamic state of an ecosystem, in which its biodiversity remains somewhat constant, it is known as this.
What is equilibrium?
200
These types of consumers are usually carnivores that eat the primary consumers. (not a specific animal)
What are secondary consumers?
200
Photoautotrophs harness the Sun’s solar energy by converting it to chemical energy in the form of this molecule that all organisms need for energy.
What is ATP? (Glucose acceptable)
300
Producers pass on this amount of their energy to the primary consumers.
What is 10%?
300
These organisms perform 40% of all photosynthesis on Earth.
What are phytoplankton?
300
The ability of an ecosystem to remain at equilibrium in spite of disturbances is called _________________.
What is resistance?
300
Identify this concept that accounts for the multiple trophic (feeding) interactions between each species and the many species it may feed on, or that feed on it.
What is a food web?
300
This process describes increasing concentrations of persistent, toxic substances in organisms increasing with each successive trophic level.
What is Biomagnification?
400
This is the name given to the collective community of living organisms and their abiotic (non-living) environment.
What is an ecosystem?
400
Terrestrial ecosystems, also known for their diversity, are grouped into large categories called ___________.
What are biomes?
400
The speed at which an ecosystem recovers equilibrium after being disturbed is called ________________.
What is resilience?
400
Each organism in a food chain occupies a specific energy level, its position in the food chain or food web. These energy levels are known as what?
What are Trophic levels?
400
In her book "Silent Spring", Rachel Carson highlights the dangers of this pesticide as it accumulated in animals.
What is dichlorodiphenyltrichloroethane, or DDT?
500
Because of biomagnification, which type of organism in the food chain would have the highest levels of pollution in them?
What is apex predator? (will accept quaternary consumer)
500
Along with mercury, this heavy metal is often found in seafood.
What is cadmium?
500
The extinction of this type of species can devistate an ecosystem.
What is a keystone species?
500
This type of food web consists of a base of organisms that feed on decaying organic matter (dead organisms), including decomposers and detritivores.
What is a detrital food web?
500
The bacteria and archaea at this hydrothermal vent, that get their energy from chemicals instead of sunlight, are known as what?
What are chemotrophs?
