Living Things in Biosphere Lesson 1: Living Things

(a)   is important for living things to carry out daily functions.

• Water
• To respond to stimuli
• To reproduce
• To provide energy

Hey there, did you know that all living creatures get their energy from the food they eat? Is that true or false?

• True

• False

Living things need space to (a)  

• respond to stimuli
• provide energy
• find water, food, and shelter
• carry out daily functions

Hey there, smarty pants! Can you tell me something? What's common in every living thing you've ever seen?

• They're all made up of tiny cells

• They all grow and develop over time

• They're all made of some kind of chemicals

• All of the above, of course!

Let's dive into the world of biology! Can you tell me the key difference between unicellular and multicellular organisms?

• Unicellular organisms perform all functions in one cell, Multicellular organisms have many cells that work together to function

• Unicellular organisms are the producers of the biological world, while multicellular organisms are the consumers

• Unicellular organisms are the heterotrophs of the biological world, while multicellular organisms are the autotrophs

• Unicellular organisms don't respond to stimuli, but multicellular organisms do respond to stimuli

Can you guess what 'homeostasis' means in the world of biology? It's a cool term!

• Is it about keeping internal conditions stable?

• Or maybe it's about changing behavior?

• Could it be about getting bigger?

• Or is it about breaking down material?

How do living organisms obtain energy?

• By eating other organisms
• By reproducing
• By responding to stimuli
• By carrying out functions

(a)   are examples of stimuli in living organisms.

• Changes in environment
• Growth and development
• Cells and chemicals
• Water and food

What is the role of cells in living organisms?

• To provide energy
• To reproduce
• To respond to stimuli
• To carry out functions

The process of growth in living organisms is (a)   .

• Getting bigger
• Changing behavior
• Breaking down material
• Reproducing
