Answer the following questions:
What is the difference between living and non-living things?
- Living things are defined as anything that requires food, water, and air to survive.
- All humans and animals require food, water, and air to survive or live, so all humans and animals are living things.
- Non-living things are things that do not require food, water, or air to survive.
What characteristics do living beings have?
All living things share some characteristics that distinguish them from non-living things. The following are the characteristics of living things:
- Food, air, and water are essential for all living things.
- Living things can grow.
- Living things can move on their own.
- Living things have the ability to respond to stimuli (changes around them).
- All living things breathe (release energy from food).
- Living things remove waste
- Living things are capable to reproduce.
Explain what is stimuli with an example.
All living things react to changes in their environment. Stimuli are environmental changes to which living things respond. When we touch the leaves of a Mimosa plant, the leaves fold up. The “touch” of a finger is the stimulus in this case, and the Mimosa plant responds by folding its leaves.
What is respiration?
Respiration is a chemical process in which food absorbed by the body combines with oxygen and releases energy.
What is breathing?
The process of introducing air into the lungs through the nose and then releasing it through the nose is called breathing.
What is excretion?
Removing waste products from the body of an organism is called excretion.
What is reproduction?
The process by which an organism produces new members of its kind is called reproduction.
How do plants reproduce?
Plants also reproduce in a number of ways:
- Many plants reproduce by seeds
- Some plants reproduce by bulbs/tubers [POTATO]
- Some plants reproduce by STEM cuttings
What is habitat?
The location or environment in which a plant or animal lives is known as its habitat. A habitat gives the whole thing to the organisms which they want to live.
All the habitats may be divided into 2 groups:
- Terrestrial habitats, and
- Aquatic habitats.
What is adaptation?
Adaptation refers to the presence of specific body features (or habits) that allow a plant or animal to live in a specific habitat.
