Conclusion
Now that you have finished the lesson you should feel a sense of accomplishment!!! Great job!! Here is a review of what you have learned....
What are living things?
Living things are organisms that display the key characteristics of life. These characteristics include the ability to grow, reproduce, take in and use energy, excrete waste, respond to the environment, and possess an organized structure.
What are non- living things?
A non-living thing is any form without life, such as an inanimate body or object. Compared with the entity that has life, a non-living thing lacks the features that characterize a living thing.
There are seven Characteristics of Living Things
1. Movement
All living things move in some way. This may be obvious, such as animals that are able to walk, or less obvious, such as plants that have parts that move to track the movement of the sun.
Earthworms use circular and longitudinal muscles to move through soil or along surfaces.
2. Respiration
Respiration is a chemical reaction that happens within cells to release energy from food.
The food that earthworms eat supplies their body with energy-rich molecules such as glucose. On entering the cells of their body, these molecules are broken down in a series of steps to release energy to be used by the body, producing carbon dioxide and water as waste products.
3. Sensitivity
The ability to detect changes in the surrounding environment.
Earthworms have light-sensitive cells scattered in their outer skin. Their skin cells are also sensitive to touch and chemicals.
4. Growth
All living things grow.
Earthworms hatch from eggs and can grow up to a metre or more in length! Some earthworms are also able to regrow small parts of their body that have been lost or injured.
5. Reproduction
The ability to reproduce and pass genetic information onto their offspring.
Earthworms have both sperm and eggs within their bodies (they are hermaphrodites) but they cannot self-fertilize and need to mate with another individual. After mating, a cocoon containing the fertilized eggs is deposited in the soil.
6. Excretion
Getting rid of waste.
Earthworms excrete waste from their anus – the last segment of their body.
7. Nutrition
The intake and use of nutrients. This occurs in very different ways in different kinds of living things.
Earthworm nutrition comes from a variety of sources, depending on their species. Food types include manure, compost, plant material, fungi, microorganisms and decaying animals. They take in food through their mouths.
Here are 5 examples of living things
- Dog
- Tree
- Flowers
- Man
- woman
Non-living things
The most important characteristic of nonliving things is the absence of protoplasm, the fundamental basis of life. For example, cells are absent in stones or any non-living things. Due to the absence of protoplasm, no metabolic activities are possible in the nonliving things.
Here are the 5 examples of Non-living things.
- air
- water
- land
- stone
- metals
