How does the concept of a biome differ from that of an ecosystem?

• A biome is smaller and more specific than an ecosystem.

• A biome is a large area characterized by its climate and dominant vegetation, while an ecosystem includes interactions between living and non-living components.

• A biome includes only abiotic factors, while an ecosystem includes only biotic factors.

• A biome is a single species, while an ecosystem is a group of species.

Which of the following best describes the biosphere?

• The biosphere is a single ecosystem.

• The biosphere includes all living organisms on Earth and their interactions with the abiotic environment.

• The biosphere is a collection of biomes with similar climates.

• The biosphere is the smallest level of ecological organization.

How can biotic factors influence the abiotic components of an ecosystem?

• Biotic factors have no influence on abiotic components.

• Biotic factors can alter the physical environment, such as plants affecting soil composition.

• Biotic factors only affect other biotic factors.

• Biotic factors can change the climate of the entire planet.

What is the primary distinction between a community and a population in ecological terms?

• A community is smaller than a population.

• A community consists of multiple populations of different species, while a population is a group of individuals of the same species.

• A community includes only abiotic factors, while a population includes only biotic factors.

• A community and a population are the same in ecological terms.

Which of the following is an example of an abiotic factor that can influence an ecosystem?

• Predation

• Temperature

• Competition

• Parasitism
