Question

1. sort the following items according to whether they would be considered living or nonliving (using the list you created above. (do not revise your list of characteristics at this point). - cat skull - plant in water - fire - pig heart removed 2 minutes ago - mushrooms - pig heart removed 5 hours ago - mechanical singing bird - tree in winter

Explanation:

Living items are those that currently exhibit key life traits like growth, metabolism, or response to stimuli. Nonliving items lack these active life characteristics, even if they were once part of a living organism or mimic life functions.

• Plant in water: Actively growing, performing photosynthesis.
• Pig heart removed 2 minutes ago: Still has viable cells for a short time post-removal.
• Mushrooms: Fungal organisms with active growth and metabolism.
• Tree in Winter: Dormant but still a living organism with active cellular processes.
• Cat skull: Remains of a once-living organism, no active life functions.
• Fire: A chemical reaction, not a living organism.
• Pig heart removed 5 hours ago: Cells have died, no active life functions.
• Mechanical Singing Bird: Man-made object, mimics a living action but is nonliving.

Answer:

Living:

• Plant in water
• Pig heart removed 2 minutes ago
• Mushrooms
• Tree in Winter

Nonliving:

• Cat skull
• Fire
• Pig heart removed 5 hours ago
• Mechanical Singing Bird
