Indra is investigating various species in the coastal town of Galveston, Texas. Her observations are shown in the image. Observations of Species in Our Ecosystem: - Organism 1 is unicellular, has no nucleus, and DNA is seen floating freely in the cell. Its cell wall contains peptidoglycan. - Organism 2 is autotrophic and can live in bodies of water that have extremely high salt levels. Which option accurately classifies the organisms described in her observations?

• Organism 1 belongs to kingdom Plantae; Organism 2 belongs to kingdom Fungi.

• Organism 1 belongs to kingdom Fungi; Organism 2 belongs to kingdom Plantae.

• Organism 1 belongs to kingdom Eubacteria; Organism 2 belongs to kingdom Archaebacteria.

• Organism 1 belongs to kingdom Archaebacteria; Organism 2 belongs to kingdom Eubacteria.

Scientists classify and name organisms in which of the following ways? Choose two correct answers.

• By using a system called binomial nomenclature

• By grouping them based on their physical and genetic characteristics

• By assigning random names to each organism

• By classifying them according to their habitat only

Scientists use the taxonomic hierarchy to be able to quickly name organisms and reduce confusion. Major kingdoms include Plantae, _____, Fungi, Protista, and Animalia. Kingdoms are divided into smaller and smaller levels until they are classified into _______ levels. Mushrooms and mold fall under the kingdom __________ while algae fall under the kingdom _____ . Choose the option that identifies the missing terms, in order of appearance in the sentences.

• Eukarya; family; Animalia; Archaebacteria

• Archaebacteria; species; Fungi; Protista

• Bacteria; class; Protista; Fungi

• Archaea; genus; Archaebacteria; Plantae

Read the descriptions of various kingdoms. 1. A species can create its own food, is plant-like, and can be found in ocean and freshwater environments. 2. A species releases proteins that help them digest their surroundings, which may include organic material. 3. A species lacks a nucleus and is commonly found in the guts of cows, so it may help with digestion. Which option matches each description with the correct kingdom, in order from 1 to 3?

• A Fungi; Eubacteria; Protista

• B Plantae; Animalia; Fungi

• C Fungi; Plantae; Animalia

• D Protista; Fungi; Eubacteria
