A collection of ecosystems
Which of the following is a biotic factor in an ecosystem?
Water
Temperature
Plants
Rocks
What is the primary difference between biotic and abiotic factors?
Biotic factors are living, while abiotic factors are non-living
Abiotic factors are living, while biotic factors are non-living
Both are living components of an ecosystem
Both are non-living components of an ecosystem
Which of the following is an example of an abiotic factor?
Fish
Soil
Trees
Birds
What is a population in the context of an ecosystem?
A single organism
A group of organisms of the same species living in an area
Different species living together
The non-living components of an environment
How does a community differ from a population?
A community includes only one species, while a population includes multiple species
A community includes multiple species, while a population includes only one species
A community is non-living, while a population is living
A community is a single organism, while a population is a group of organisms
Which of the following best describes an ecosystem?
A single organism
A group of the same species
A community of living organisms and their physical environment
The non-living components of an environment
Identify an example of a community within an ecosystem.
All the fish in a pond
The water in a pond
The rocks around a pond
All the plants, animals, and microorganisms in a pond
How might a change in an abiotic factor, like temperature, affect a community within an ecosystem?
It would have no effect
It could change the types of species that can survive there
It would only affect the non-living components
It would only affect the water levels
Which of the following scenarios best illustrates the concept of a population?
A single tree in a forest
All the oak trees in a forest
All the trees in a forest
The soil in a forest
Which of the following is an example of an organism?
A forest
A wolf
A pack of wolves
A mountain range
How do biotic factors influence abiotic factors in an ecosystem?
Biotic factors have no influence on abiotic factors
Biotic factors can alter abiotic factors, such as plants affecting soil quality
Abiotic factors always control biotic factors
Biotic factors only affect other biotic factors
What is the role of a community in an ecosystem?
It represents the non-living components
It includes all the living organisms interacting in a specific area
It is the smallest unit of an ecosystem
It only includes one species
Which of the following is a correct example of an ecosystem?
A single fish
A lake with fish, plants, water, and rocks
A group of fish
A forest with only trees
How can changes in a population affect the community and ecosystem?
Changes in a population have no effect on the community or ecosystem
Changes in a population can alter food chains and resource availability
Changes in a population only affect abiotic factors
Changes in a population only affect the individual organisms
What is the relationship between organisms and populations?
Organisms are larger than populations
Populations are made up of organisms of the same species
Populations are made up of different species
Organisms and populations are the same
