The biosphere is defined as which of the following?
The part of Earth where life exists, including land, water, and air.
Only the land portion of Earth.
Only the water bodies on Earth.
Only the atmosphere of Earth.
An ecosystem is:
a community of living organisms interacting with their environment
a single organism living alone
a group of rocks and minerals
a type of weather pattern
A community is different from a population in that:
A community consists of different species living together, while a population consists of individuals of the same species.
A community consists of only plants, while a population consists of only animals.
A community is smaller than a population.
A community refers to a single organism, while a population refers to many organisms.
Define population and provide an example from your notes.
A population is a group of individuals of the same species living in a specific area; for example, all the deer in a forest.
A population is a group of different species living together; for example, deer and rabbits in a forest.
A population is the total number of plants in a garden; for example, all the flowers in a park.
A population is a group of animals living in different areas; for example, deer in various forests.
A habitat is:
the natural home or environment of an animal, plant, or other organism.
a type of food that animals eat.
a tool used by animals to build nests.
a place where animals go to sleep during the day.
What level of organization is defined as a living thing capable of functioning on its own?
Cell
Organ system
Tissue
Organ
The level of organization that refers to all members of a single species living in a particular area is called:
Community
Population
Ecosystem
Organism
What is the difference between biotic and abiotic factors? Provide 2 examples of each.
Biotic factors are living things like plants and animals, while abiotic factors are non-living things like sunlight and water.
Biotic factors are non-living things like rocks and soil, while abiotic factors are living things like bacteria and fungi.
Biotic factors include sunlight and temperature, while abiotic factors include trees and insects.
Biotic factors are things like water and air, while abiotic factors are things like grass and birds.
What type of organism makes its own food using the sun’s energy?
Producer
Consumer
Decomposer
Parasite
Only 10% of energy is passed to the next trophic level. Where does the rest of the energy go?
It is lost as heat, used for metabolic processes, or remains in undigested parts.
It is stored in the next trophic level.
It is converted entirely into biomass.
It is recycled back to the sun.
Put these in correct order for a food chain: fox, grass, mountain lion, rabbit.
grass, rabbit, fox, mountain lion
rabbit, grass, fox, mountain lion
fox, rabbit, mountain lion, grass
mountain lion, fox, rabbit, grass
