3. Watch the power point about the 7 life processes

Let’s review:
The 7 processes that make something alive are:

4. MOVEMENT – Release Energy
Photosynthesis Movement
Reproduction
Growth
PLANTS ANIMALS
Plants release energy
through their life
processes like growth
and photosynthesis.
Animals release energy by
movement.

PHOTOSYNTHESIS

6. Photosynthesis- The process plants
use to make food.
A plant needs light
energy from the sun
plus carbon
dioxide(CO2), plus
water. The plant will
make sugar and oxygen.

7. REPRODUCTION- To make
more
Living things must reproduce because they would
otherwise go extinct.

adolescent
adult

8. Reproduction
in Animals
• Creates more of the same species
Reproduction
in plants
• Pollination, seed dispersal, germination

9. SENSITIVITY- reacting to your
surroundings

Stimulus and response

10. 1. Stimulus- Anything that causes a living thing to react
2. External Stimulus- Anything in an organism’s environment that causes it to
react. Example: ________________
3. Internal Stimulus- Anything within an organism that causes it to react.
Example: Hunger
Plants • React to light, water,
weather
Animals
• Use their 5 senses to
react

11. A cold wind
blows on you
A plant needs
water
A moth detects
a bat’s sound
waves
A dog sees a
can of food
opening
How do living things detect stimuli?

12. NUTRITION-Taking in nutrients
Makes seeds
Moves water
from roots
and leaves
Suck up water
and minerals
Makes food through
Photosynthesis. It needs
water + sun + carbon
dioxide

13. Digestive System- Breaks down food and gives
nutrients to the body and gives animals energy.

14. With a partner, read A32 to A36. Copy and complete the
chart below in your notebook. Hint: Use the chart on A 33
to help.
Main Idea: The digestive system breaks down food and gives
nutrients to the body which gives us energy.

Answer these questions:
• What category of food do you eat most of?
• Least of?
• What can you do to make your diet better?

15. EXCRETION- Creates waste
and RESPIRATION- breathing
Respiratory System- A group of organs that
work together to bring air in and push it back
out of the body.

18. GROWTH- The development of a living
thing often by growing in size and
maturity.
Animals need to grow to reproduce , care for selves and
be productive.
Question: How is your growth similar to a seed growing?
