What is a food chain?
A type of exercise routine
A method of food preservation
A type of cooking utensil
A series of organisms each dependent on the next as a source of food.
Name three abiotic factors in an ecosystem.
Animals, bacteria, and fungi
Rocks, soil, and plants
Wind, fire, and pollution
Sunlight, temperature, and water
What are biotic factors?
Living components of an ecosystem
Weather patterns in an ecosystem
Chemical reactions in an ecosystem
Non-living components of an ecosystem
What is ecological succession?
The process of change in the species structure of an ecological community over time.
The process of change in the political dynamics of an ecological community over time.
The process of change in the weather patterns of an ecological community over time.
The process of change in the geological structure of an ecological community over time.
What are producers in an ecosystem?
Organisms that produce their own food through photosynthesis or chemosynthesis
Organisms that do not play a role in the ecosystem
Organisms that only eat other organisms
Organisms that rely on other organisms for food
How does sunlight contribute to energy flow in an ecosystem?
Sunlight is used by animals for respiration
Sunlight is used by plants in photosynthesis to produce food, which then becomes the energy source for other organisms in the ecosystem.
Sunlight is converted directly into energy by organisms
Sunlight has no impact on energy flow in an ecosystem
Explain the concept of energy transfer in an ecosystem.
Energy transfer in an ecosystem is the process of converting sunlight into heat
Energy transfer in an ecosystem involves the movement of energy from one organism to another through the food chain.
Energy transfer in an ecosystem involves the exchange of water between organisms
Energy transfer in an ecosystem is driven by the movement of rocks from one place to another
In an energy pyramid, which level contains the most energy?
Tertiary consumers
Secondary consumers
Primary consumers
Producers
What is the correct order of trophic levels from bottom to top in a typical food chain?
Producers, Secondary consumers, Primary consumers, Tertiary consumers
Producers, Primary consumers, Secondary consumers, Tertiary consumers
Tertiary consumers, Secondary consumers, Primary consumers, Producers
Primary consumers, Producers, Secondary consumers, Tertiary consumers
What percentage of energy is typically transferred from one trophic level to the next?
1%
10%
25%
50%
In a food chain, what role do decomposers play?
They produce energy for the ecosystem
They consume primary consumers
They break down dead organisms and recycle nutrients
They are the top predators
What is the main difference between a food chain and a food web?
A food chain is more complex than a food web
A food web consists of multiple interconnected food chains
A food chain includes decomposers, while a food web does not
A food web is linear, while a food chain is not
Which of the following best describes an energy pyramid?
A diagram showing the flow of energy through a food web
A representation of the number of organisms at each trophic level
A graphical representation of energy flow in an ecosystem
A chart showing the biomass of organisms at each trophic level
In a food chain, which of the following organisms would be considered an apex predator?
Grasshopper
Frog
Snake
Lion
Animal that gets its energy and nutrition from eating meat.
Detritivore
Ominvore
Carnivore
Herbivore
in an energy pyramid, which way does the energy transfer?
from top of the pyramid to the bottom
from the bottom of the pyramid to the top
all of these
none of these
Primary succession begins where there was no ecosystem and no soil such as
a severe storm
a volcanic eruption
an old farm is abandoned
a forest fire
Secondary succession (thnk soil) forms after a catastrophic event like a forest fire and has a ___________ growth rate than primary succession because soil already exists.
extremely slower
slower
faster
What is the definition of - Herbivore
An organism that obtains energy by eating both plants and animals
The rate at which organic matter is created by producers in an ecosystem
An organism that obtains energy by eating only plants
An organism that obtains energy by eating only animals
What is the definition of - Omnivore
An organism that obtains energy by eating both plants and animals
An organism that feeds on plant and animal remains and other dead matter
An organism that obtains energy by eating only plants
Series of steps in an ecosystem in which organisms transfer energy by eating and being eaten.
What is the definition of - Ecological pyramid
A network of complex interactions formed by feeding relationships among the various organisms in an ecosystem.
Steps in a food chain or food web
A diagram that shows the relative amounts of energy of matter within each trophic level in a food chain or food web.
Total amount of living tissue within a given trophic level
What is the definition of - Biomass
A network of complex interactions formed by feeding relationships among the various organisms in an ecosystem.
Steps in a food chain or food web
A diagram that shows the relative amounts of energy of matter within each trophic level in a food chain or food web.
Total amount of living tissue within a given trophic level
