A chemical element in the soil
A weather condition
Which level of organization includes all the living and non-living things in a particular area?
Population
Community
Ecosystem
Organism

Organism
Population
Community
Ecosystem
Which of the following is an example of a community?
All the frogs in a pond
All the living and non-living things in a forest
All the different species of plants and animals in a meadow
The air, water, and soil in a desert
Which level of organization is represented by all the ecosystems on Earth?
Community
Population
Biosphere
Organism
Which of the following best describes the relationship between abiotic and biotic factors in an ecosystem?
Abiotic factors only affect other abiotic factors
Biotic factors only affect other biotic factors
Abiotic and biotic factors interact and influence each other
Abiotic and biotic factors do not interact
If the temperature in a pond increases significantly, which of the following is a likely effect on the biotic factors?
The number of rocks increases
Some fish species may die or move away
The amount of sunlight decreases
The water becomes less wet
A scientist observes that a decrease in rainfall leads to fewer plants in a grassland. Which type of factor is rainfall, and how does it affect the ecosystem?
Biotic; it increases plant growth
Abiotic; it influences the number of plants
Biotic; it decreases animal populations
Abiotic; it has no effect on the ecosystem
Which scenario best illustrates the concept of a population within an ecosystem?
All the birds, insects, and mammals in a forest
All the oak trees in a forest
All the rocks and soil in a field
All the water in a lake
How might removing a top predator from an ecosystem affect the community?
It would have no effect
It could cause an increase in prey populations, affecting other species
It would only affect abiotic factors
It would only affect the biosphere
Which of the following is an example of how a biotic factor can affect an abiotic factor?
Sunlight causing plants to grow
Plants releasing oxygen into the air
Rocks breaking down into soil
Rainfall increasing water levels
A drought reduces the water available in a wetland. Predict how this abiotic change could impact the biotic community.
The number of plant and animal species may decrease
The rocks will multiply
The sunlight will increase
The soil will turn into water
A student claims that soil is a biotic factor because it contains living organisms. Evaluate this claim.
The claim is correct because soil is alive
The claim is incorrect; soil is abiotic, but it contains biotic components
The claim is correct because all parts of soil are living
The claim is incorrect; soil is only biotic
Given a scenario where a new plant species is introduced into a forest ecosystem, predict and explain one possible effect on the existing community.
No effect, because new plants do not interact with other species
The new plant could compete with native plants for resources, possibly reducing their populations
The new plant will only affect abiotic factors
The new plant will immediately become extinct
Analyze how a decrease in sunlight due to prolonged cloud cover might affect both abiotic and biotic factors in a pond ecosystem.
Only the water temperature will change
Plant growth may decrease, leading to less food for herbivores
Only the fish population will increase
The amount of soil will increase
A city plans to build a road through a forest. What is a possible impact on the ecosystem’s levels of organization?
Only the biosphere will be affected
The road could fragment populations and communities, affecting the ecosystem
Only abiotic factors will change
The road will have no impact
Suppose a disease wipes out a population of rabbits in a grassland. How might this affect the other levels of organization in the ecosystem?
Only the rabbit population will be affected
Predators that eat rabbits may decrease, and plant populations may increase
The biosphere will collapse
Only abiotic factors will be affected
