Question

name: life science homework - unit 2.3 responses to changes in ecosystems (ge/tt) vivid vocabulary - write a definition and draw a colored picture for each word. vocabulary term | definition - in your own words | picture phototropism geotropism hibernation migration dormancy circadian rhythm

Explanation:

This is a life science (biology) vocabulary assignment. Here are definitions for each term:

• Phototropism: The way plants grow towards (positive) or away from (negative) light. For example, sunflowers turning to face the sun.
• Geotropism (Gravitropism): How plants respond to gravity—roots grow down (positive geotropism), stems grow up (negative geotropism). Like a potted plant tipped over, roots will curve down.
• Hibernation: A long, deep sleep-like state some animals enter in winter to save energy when food is scarce. Bears, for instance, hibernate in caves.
• Migration: The seasonal movement of animals from one place to another, often to find food, mate, or better climate. Birds flying south for winter.
• Dormancy: A period of inactivity in plants/animals, slowing growth/metabolism (e.g., seeds waiting for right conditions to sprout).
• Circadian Rhythm: A daily (about 24-hour) biological cycle in living things, like sleep-wake cycles in humans or opening/closing of flowers.

For pictures, draw relevant scenes: sun for phototropism, roots/stems for geotropism, a hibernating bear, migrating birds, a dormant seed, and a clock with a sleeping/waking person for circadian rhythm.

Answer:

Vocabulary Term	Definition - In Your Own Words	Picture (Description)
Geotropism	Plants grow toward/away from gravity (roots down, stems up).	Potted plant with roots curving down after tipping.
Hibernation	Animals sleep deeply in winter to save energy (food scarce).	Bear sleeping in a cave.
Migration	Animals move seasonally for food, climate, mating.	Flock of birds flying south.
Dormancy	Living things pause growth/activity (e.g., seeds, plants in winter).	A seed in soil waiting to sprout.
Circadian Rhythm	24-hour biological cycle (sleep, flower opening, etc.).	Person sleeping at night, awake during day; or flower opening in morning, closing at night.
