Unit 5 Ecosystems

What is the definition of abiotic?

• non-living things in the ecosystem

• producers

• the place in an ecosystem where an organism lives

• population

Define "habitat."

• the path of food energy from the sun to the producer to a series of consumers (showing the feeding relationships in an ecosystem)

• all organisms of the same species that live in the same place at the same time

• the place in an ecosystem where an organism lives

• all organisms of the same species that live in the same place at the same time

Which is the correct order of the levels of organization in an ecosystem from least to most diverse?

• population<organism<ecosystem<community<biome<biosphere

• organism< population<ecosystem<community<biome<biosphere

• organism<population<community<ecosystem<biosphere<biome

• organism<population<community<ecosystem<biome<biosphere

Which organisms mostly reproduce asexually?

• animals

• fungi

• plants

• fish

Define "food chain."

• a large region of land with a distinct climate and certain types of plant and animal life

• all organisms of the same species that live in the same place at the same time

• the part of the Earth that is able to support life

• the path of food energy from the sun to the producer to a series of consumers (showing the feeding relationships in an ecosystem)

Which of the following statements best describes the relationship between ecosystems and biomes?

• An ecosystem may contain many biomes, and biomes within the same ecosystem are typically home to similar species of organisms.

• A biome may contain many ecosystems, and ecosystems within the same biome are typically home to similar species of organisms.

• Both biomes and ecosystems are characterized by their climate conditions and the communities that live in them; however, biomes refer to land environments and ecosystems refer to aquatic environments.

• Both biomes and ecosystems are characterized by their climate conditions and the communities that live in them; however, ecosystems refer to land environments and biomes refer to aquatic environments.

What is the relationship between a niche and a habitat?

• A niche is the role an organism takes within a place called a habitat.

• Both niches and habitats are synonyms for the word “population.”

• Niches are types of organisms that live in habitats.

• A niche is the place where an organism lives, and the habitat is the role that organism takes in the niche.
