48)•Ecology is the study of the

interactions of organisms with one another and with their environment.

•Eco means “house”•Ology means “study of”

•Why do you think we use the root word eco for this term?

Biotic factors interact with an

ecosystem.•Biotic: all of the organisms that live

together and interact with on another.

Plants

• Plants, as a biotic factor in land ecosystems, affect other biotic and abiotic parts of ecosystem.

• Plants are an important source of food.

• The types of plants found in a particular ecosystem will determine the types of animals that can live there.

• Plants can affect temperature by blocking sunlight.

• Plant roots hold soil in place.

• Even the atmosphere is affected by plants taking in carbon dioxide and releasing oxygen.

Animals

• Animals, as biotic factors, also affect an ecosystem. • A beaver that builds a dam changes the flow of a

river and so affects the surround landscape.

Many abiotic factors affect

ecosystems.• Abiotic factors include both the physical and

chemical parts of an ecosystem. • Physical factors are factors that you can see

or feel , such as the temperature or the amount of water or sunlight.

• Important chemical factors include the minerals and compounds found in the soil and whether the water is fresh or salty.

Temperature • Temperature is an important abiotic

factor.

• Temperature affects the types of plants that will survive.

• The types of plants determine what types of animals will live there.

• Animals are also sensitive to temperature.

What kind of environment will these animals be found in?

• Look at the picture of the pond ecosystem above.

• With the person sitting next to or behind you, find as many abiotic and biotic factors as you can.

• Take 5 minutes with a partner and then we will share.

Identifying Abiotic & Biotic Factors

• With your row neighbor(s), take a look at the cards on your desk.

• Separate out the cards into two piles, one for biotic and one for abiotic

• You will have 5 minutes to work together

• We will then share our answers as a class

Your Homework Tonight!

• Please name 3 biotic factors and 3 abiotic factors that you see around your home.

• Please name at least one way that these two depend on each other.

• Then put these observations together into a 5-sentence descriptive paragraph.

• You may write this homework assignment on the back of your Cornell Notes!
