Archaea, EuBacteria, Eukarya, and Ecosystems

A scientist collects one species from a rainforest and takes it back to the lab for further studies. The scientist finds that genetic material (DNA) floats freely in the species, and it lacks a nucleus. It was also found in an environment that was approximately 100 degrees Celsius (near boiling temperature).

• Eubacteria, because it is a prokaryote that does not live in extreme environments

• Archaea, because it is a eukaryote that does not live in extreme environments

• Eubacteria, because it is a eukaryote that lives in an extreme environment

• Archaea, because it is a prokaryote that lives in an extreme environment

Which of the following is true regarding the importance of a kingdom to its ecosystem?

• The Eubacteria kingdom is important because all organisms in this kingdom are producers.

• The Archaea kingdom is important because it contains multicellular organisms that provide food for other kingdoms.

• The Eubacteria kingdom is important because it contains multicellular organisms that eat other organisms.

• The Archaea kingdom is important because it contains some species that break down wastes in their ecosystem.

Read each of the descriptions of a species from a particular kingdom. 1. Usually producers in extreme environments such as low-oxygen or high-temperature 2. Unicellular organisms that are not found in very extreme environments 3. Have a cell wall that retains its shape when the environment changes 4. Some help to produce methane used for decomposition Which descriptions likely describe Archaebacteria?

• 1 and 4

• 2 and 3

• 3 and 4

Identify which kingdom the organism in the image belongs to and identify a reason this organism is important in ecosystems (be sure to look at the shape).

Choose 2 correct answers

Choose the option that accurately classifies and describes the organism in the diagram.

• The organism is a protist; it is unicellular, autotrophic, and likely reproduces asexually.

• The organism is a plant; it is multicellular, autotrophic, and likely reproduces sexually.

• The organism is a animal; it is multicellular, heterotrophic, and likely reproduces asexually.

• The organism is a fungus; it is unicellular, heterotrophic, and likely reproduces sexually.

A scientist studies a multicellular organism growing on a dead log. The organism does not make its own food. Instead, it breaks down matter in the log.

• The organism belongs to the kingdom Fungi.

• The organism belongs to the kingdom Plantae.

• The organism belongs to the kingdom Protista.

• The organism belongs to the kingdom Animalia.

Why are protists and fungi important in ecosystems?

• Protists produce oxygen and fungi decompose organic matter.

• Protists decompose organic matter and fungi produce oxygen.

• Protists and fungi both make food through photosynthesis.

• Protists and fungi are not important in ecosystems.

The organism shown in the image has a cell wall. Based on the image and the description, identify which kingdom the organism belongs to.
