Question

1. a dichotomous key is shown for determining the kingdom of an organism. in what kingdom would a multicellular organism be classified if it cannot make its own food, but is able to ingest food? a eubacteria b plantae c animalia d fungi 16. jonah knows that eukaryotes are classified into four kingdoms according to certain characteristics. the diagram shows some characteristics of the four kingdoms. if jonah knows that almost all plants are multicellular, and must make their own food, which of the four kingdoms most likely represents kingdom plantae? a kingdom 1 b kingdom 2 c kingdom3 d kingdom4 17. which kingdom is found in harsh environments where other organisms cannot survive? a archaebacteria b eubacteria c fungi d protista

Explanation:

15.

• Eubacteria: Unicellular prokaryotes.
• Plantae: Multicellular, autotrophic (make their own food).
• Animalia: Multicellular, heterotrophic (ingest food).
• Fungi: Multicellular (most), heterotrophic (absorb food).

Since the organism is multicellular, cannot make its own food but can ingest food, it fits the characteristics of Animalia.

• Kingdom 1: Unicellular, heterotrophic.
• Kingdom 2: Unicellular, autotrophic.
• Kingdom 3: Multicellular, heterotrophic.
• Kingdom 4: Multicellular, autotrophic or heterotrophic.

Plants are multicellular and autotrophic (make their own food), so Kingdom 4 which has the multicellular and autotrophic option most likely represents Plantae.

• Archaebacteria: Known to live in harsh environments (e.g., hot springs, high - salt areas) where other organisms cannot survive.
• Eubacteria: Found in more common environments.
• Fungi: Found in a variety of environments but not typically in the most extreme harsh ones.
• Protista: Found in aquatic and moist environments.

Answer:

C. Animalia
