Biotic & Abiotic Factors

Someone give a summary about “Hunger Games” Are you a Survivor? Someone give a summary about “Hunger Games”

What does it take to survive? Could you do it? Students work on white boards in groups to make a list of things you would take if you had to go to the hunger games. Work with a partner to make a list. What would you take on a survivor trip?

What do other living organisms need to survive?

Survival Needs Energy (food) Shelter Space Soil Climate/weather Mates Students list what they need to survive

Living vs. Nonliving We are surrounded by living and non-living things. A cat playing with a toy is obviously living. A pigeon flying from a tree … both tree and pigeon are living

So, what are the Characteristics of living things again?

The Characteristics of Life All living things…. …no matter how different from each other they may be…. ….share a set of common characteristics.

Living things… ….are made up of units called cells. ….reproduce.

Living things… ….grow and develop. ….use energy. ….are based on a universal genetic code called DNA. ….grow and develop. ….use energy.

Living things… ….respond to their environment (stimuli). Movement question is to have students realize that all living organisms show movement of one kind or another. All living organisms have internal movement, which means that they have the ability of moving substances from one part of their body to another. Some living organisms show external movement as well - they can move from place to place by walking, flying or swimming. ….maintain homeostasis.

Living things… ….evolve, or change, over time.

Biotic All living factors within an environment. Bacteria Yeast: A unicellular fungi All living factors within an environment.

Biotic What does the prefix “bio” mean? What are the non-living things called? Think of the prefix “a”

All non-living factors within an environment. Abiotic All non-living factors within an environment.

How a biotic organisms adapts to it’s abiotic factors & interacts with other living factors determines it’s survival.

Abiotic Factors help Biotic organisms meet their needs for survival Ex: Carbon dioxide Temperature Soil Sunlight Nutrients Water Space Oxygen

How might this affect the organisms that live here? Abiotic Factors: Sunlight Is there a lot or a little in this environment? Temperature Is it hot or cold? How might this affect the organisms that live here?

Light and Temperature What do you notice about the light? Light - Have students discuss the amount of light in different ecosystems. What about the light that reaches (or doesn’t reach) the rain forest floor? How does that differ from what happens in a desert? Temp – what happens to an environment when temperature is a limiting factor? Ex. Deserts and tundra, deep sea vents. Could you survive where these musk ox do?

Water Necessary for all life (as we know it). How does the amount of water affect an ecosystem?

Space Every living organism needs room to find food, find a mate, find shelter and more!

How does soil play a part in an ecosystem? What does soil provide?

What is nonliving in this picture?

Which circle is biotic and which is abiotic? You can use a venn diagram to show the similarities and differences between ideas. Which circle is biotic and which is abiotic? What could you write in the center?

Identify the Biotic and Abiotic factors in your venn diagram Biotic Abiotic Biotic and abiotic factors combine to create a system (ecosystem)
