An environment has two parts
An Environment Has Two Parts

  • Biotic: the living parts of an environment

  • Abiotic:all the physical factors (like water, soil, light and temperature) or things that are not living that affect living things in that area


How many living and non-living things can you name in this picture?



  • If we’re unsure whether an element is biotic or abiotic, we can use the characteristics of living things to help us out!

    • Living things can grow or change

    • Living things can reproduce

    • Living things can use energy


  • Biotic elements must have ALL characteristics of living things, so if you can’t eliminate one characteristic, check out the others!

    • Ann Marie doesn’t know whether the Sun grows over time, but she knows the Sun CANNOT reproduce.

    • IS THE SUN ABIOTIC OR BIOTIC? WHY?


1. A lynx:

____ Is it made of cells?

_____ Does it grow or change?

_____ Does it reproduce?

_____ Can it use energy?

Is this an example of a biotic or an abiotic element?: _______________


2. A weeping willow tree

_____ Is it made of cells?

_____ Does it grow or change?

_____ Does it reproduce?

_____ Can it use energy?

Is this an example of a biotic or an abiotic element?: ________________


3 water
3. water

_____ Is it made of cells?

_____ Does it grow or change?

_____ Does it reproduce?

_____ Can it use energy?

Let s give it a try
Let’s Give it A try!

We live in an ecosystem (remember this word for later) that depends on biotic and abiotic factors.

Challenge: Find and sort the most abiotic and biotic factors out of everyone in the class.


Draw this in your notebook
Draw this in your notebook:

Biotic Abiotic__


Challenge details
Challenge Details:

  • You will have 5minutes outside.

  • In that time, you will have to find and sort as many bioticand abiotic factors as you can.

  • The winner will get a no homework pass.


Remember that word that i told you to remember for later

  • Who was paying attention?

  • (I feel a table group point coming on!)


Ecosystem
Ecosystem!

  • Ecosystem- All the biotic and abiotic factors

    in an environment put together.


Everything in nature is connected
Everything in Nature is Connected

  • Think about this:Alligators dig underwater holes to escape from the heat. Later, after the alligators abandon their holes, fish and other aquatic organisms live in them when the water level gets low during a drought. Alligators also build nest mounds in which to lay their eggs, and they enlarge these mounds each year. Eventually, the mounds become small islands where trees and other plants grow. Herons, egrets, and other birds build their nests in the trees.


Critical thinking
Critical thinking!

  • How might our ecosystem change if we didn’t have abiotic factors?

  • Would it matter? Be ready to explain!


Biotic and Abiotic Factors

How would you describe this ecosystem?

What abiotic factors play a role in this ecosystem?

What biotic factors play a role in this ecosystem?

None, except for rain.


Biotic and Abiotic Factors

How do the biotic and abiotic factors interact?

Without the soil, sunlight, and the warm temperature none of the biotic factors (plants and animals) would be able to survive.

Try the rest on your own!


For the next 3 slides:

List the biotic factors.

List the abiotic factors.

List the climate.

Write at least 3 sentencesexplaining how the biotic and abiotic factors are interconnected.
