Levels of Organization/ Cycles DOL

Which of the following is the correct order of organization in living things from most basic (simple) to most complex?

• organism, cell, tissue, organ, organ system

• organ system, organ, tissue, cell, organism

• cell, tissue, organ, organ system, organism

• cell, organ, tissue, organism, organ system

 What is a tissue?

• A group of similar cells working together.
•  A group of similar organs working together.
• A specific structure inside of an organism.
• The largest structure in a eukaryotic organism.

In what order are the levels in the diagrams?

• Population --> Community --> Ecosystem

• Organism --> Community --> Population

• Organism --> Population --> Community

• Ecosystem --> Population --> Community

Which answer best describes a community?

• Praying mantises caring for their young

• Three-spined sticklebacks living in estuaries

• Different species of lizards occupying the same niche in a desert

• Roosting mother bats recognizing their offspring

Recent studies in bone research indicate that using ultrasound on a broken bone can decrease the healing time by 25%. Which of these are the most basic levels of organization involved when a bone heals?

• cells and tissue

• cells and organ system

• organ system and organism

• Tissue and organ system

Which component can be added to the flask to reduce the concentration of carbon dioxide in the model atmosphere created by the disks?

• Bacteria to use carbon during nitrification

• Plants to absorb carbon in the process of photosynthesis

• Snails to use carbon cellular respiration

• Mushrooms to absorb carbon during decomposition

What would be the most likely effect of a wildfire that burned a large area of a forest?

• More sugars and starches would be available for animals in the area

• The availability of fossil fuels for use by industries in the area would be reduced

• Less carbon dioxide would be removed from the atmosphere in the area by plants

• An increase in animal respiration would increase the release of carbon dioxide in the area

As part of the nitrogen cycle, animals acquire some amino acids by doing which of the following?

• Breathing air

• Eating plants

• Drinking water

• Producing waste

Atmospheric nitrogen has to be combine with other elements, or fixed, in order to be used by plants. Lightning is one way that nitrogen is fixed. When lightning occurs, the extreme heat breaks the bonds in nitrogen molecules, allowing nitrogen to combine with oxygen and form nitrogen oxides. In what way are most of the nitrogen fixed by lightning made available for use by plants?

• It is moved by the wind toward dry areas

• It is incorporated into the exoskeletons of flying insects that eat plants

• It is inhaled and exhaled by birds roosting in trees during rainstorms

• It is carried by rain to the soil

What does NOT produce carbon dioxide?

• Photosynthesis
• Burning Fossil Fuels
• Animal respiration
• Plants decaying
