Ecosystem review

Biodiversity refers to...

• the variety and variability of living organisms within a particular ecosystem, biome, or the entire planet

• large geographical areas with the same climate and ecosystems

• all the abiotic and biotic factors in an environment

• all the organisms that live in a particular habitat

Biodiversity is important because...

• it is important for promoting ecosystem resilience

• classify organisms

• creating dichotomous keys

• describing how organisms evolved

An ecosystem is a biological community of interacting organisms and ...

• the weather

• their physical environment

• the habitat they live in

• predators who hunt in the ecosystem

Biodiversity can be described at three levels...

• Morphological, Biological and Phylogenetic level

• Species, Morphological and Genetic level

• Species, Ecosystem and Genetic level

• Genetic, Morphological and Biological level

Which of the following is not a species concept

• Genetic Species concept

• Morphological Species Concept

• Phylogenetic Species Concept

• Biological Species Concept

Classifying organisms is important because it helps ...

• It allows biologists to communicate with one another

• tell what habitat organisms live in

• tell scientists what organisms are important

• it allows animals to be combined into one group

Prokaryotes and Eukaryotes are split into two groups based on

• the size of their ribosomes
• the presence or absence of a nucleus
• the number of chromosomes
• the color of their cell membrane

The 6 main kingdoms are

• Animalia, Plantae, Fungi, Protista, Archaea, Bacteria
• Eukarya, Archaea, Bacteria, Protista, Fungi, Plantae
• Monera, Protista, Fungi, Plantae, Animalia, Chromista
• Mammalia, Reptilia, Aves, Amphibia, Pisces, Insecta

Organisms in the Plantae kingdom gain energy through

The two levels of classification used in binomial naming are

• class and order
• genus and species
• kingdom and phylum
• family and genus
