Explanation:
a.) Give one example of how animals respond to their environment
b.) Give one example of how plants respond to their environment
Answer:
1. Animals may to environmental stimuli through behaviors that include hibernation, migration, defense, and courtship. As a result of cold, winter weather some animals will hibernate. Examples of hibernating animals maybe ants, snakes, black bears, beavers, and ground squirrels.
2. Plants grow towards the light. Plant leaves bud and seeds germinate when the temperature is right. Their roots and stems grow in certain directions in response to the pull of gravity.
Explanation:
Answer:
a) For example, a cat may see a saucer of milk. Information from
the cat’s eyes travels along nerve cells to the brain, where the brain
processes the information. If the brain decides it wants the milk,
the brain sends a signal to the muscles in the cat’s limbs, and the cat
moves to the saucer of milk and drinks it
Explanation:
b) For example,
specialized cells in the leaves of trees detect the decrease in sunlight
as winter approaches. Chloroplasts then reduce production of green
chlorophyll. As existing chlorophyll is broken down, other coloured
particles are revealed, creating the beautiful red- and orange-coloured
leaves we see during autumn. Th e leaves eventually die and fall off . In
the spring, increased sunlight and warmer temperatures promote the
production of new leaves containing large amounts of chlorophyll, and
the green colour returns to the leaves.
