Study Notes
Energy and Living Things
- Living things, such as hummingbirds, need energy to survive and perform daily activities like flying.
- Energy from the Sun is called solar energy.
How Plants Get Energy
- Plants make their own food using energy from the Sun, water, and air.
- This process allows plants to survive, grow, and produce new plants, flowers, or fruits.
- Plants store some of the energy they produce in their cells, which can be used when the Sun is not shining.
How Animals Get Energy
- Animals cannot make their own food and must get energy by eating other organisms or plants.
- When animals eat plants or other animals, energy is transferred from the food source to the animal.
- Not all energy from a plant is transferred to an animal that eats it; some energy is used by the plant for its survival.
Experiment: How Light Affects Plant Growth
- An experiment was conducted to compare the growth of grass seedlings in light and dark conditions.
- The results of the experiment can help us understand how light affects plant growth.
Key Concepts
- Energy is essential for the survival and growth of living things.
- Plants get energy from the Sun, water, and air to make food.
- Animals get energy by eating plants or other animals, transferring energy from one organism to another.
Test your knowledge on how plants produce food through photosynthesis and the importance of this process for their survival and growth.
