Living Things Feel Changes Around Them

key notes:

Sensitivity to the Environment:

Living things, like humans, animals, and plants, can sense changes in their surroundings, such as temperature, light, sound, and touch. This ability is called “sensitivity.”

How Humans Feel Changes:

• Touch: Humans can feel things like heat, cold, or texture by touching them with their skin.

• Sight: Humans can see changes in light and colors.

• Hearing: Humans can hear sounds around them, like a ringing phone or loud music.
• Smell: Humans can smell different scents, like flowers or food.

How Animals Feel Changes:

• Animals also have senses like humans, such as hearing, sight, and smell.
• For example, dogs can hear sounds that humans cannot, and some animals can sense changes in weather.

Plants and Sensitivity:

• Plants can also feel changes, but in different ways. For instance, plants grow toward light (phototropism) and can bend toward a source of water (hydrotropism).
• Some plants may close their leaves when touched, like the sensitive plant (Mimosa pudica).

Purpose of Sensitivity:

• The ability to feel changes helps living things survive. For example, animals can feel danger and run away from predators, while plants move toward sunlight to make food.

Adaptations:

Different living things have special abilities to feel changes. For example, birds have very good eyesight to detect food or predators from far away.
