Word Book definition

Biotic factorliving parts of an ecosystem

Abiotic factornonliving parts of an ecosystem

Biospherepart of Earth that supports life, including the top portion of Earth’s crust, the atmosphere, and all the water on Earth’s surface

Ecologystudy of the interactions that take place among organisms and their environment

Ecosystemall the living organisms in an area, as well as the nonliving parts of their environment; community of organisms that interact with each other


Biotic

biotic

  • Living parts of the ecosystem

  • Also, those things that were once living

  • Plants, animals, bacteria


Abiotic

Abiotic

  • nonliving parts of the ecosystem

  • Sunlight, water, temperature, soil, air

  • “A” means “not”


What s in the scene abiotic vs biotic

“What’s in the scene?”Abiotic vs. Biotic

Make two columns and label one “abiotic” and the other one “biotic”

Examine the picture and write in each column as many abiotic and biotic factors as you can find


Bellringer

On the coral reef ecosystem figure shown, which factor is biotic?

a.rocksc.sea horse

b.sandd.water

On the coral reef ecosystem figure shown, which factor is abiotic?

a.algaec.rock

b.sharksd.sponges

  • An aquarium of turtles can be considered a small ecosystem. Which of the following is an example of how the turtles could interact with an abiotic part of the aquarium ecosystem?

  • A. turtles eat insects you place in the aquarium

  • B. turtles fight each other for food

  • C. turtles move onto rocks heated by sunlight

  • D. turtles pull into their shells when you startle

  • them


Abiotic and biotic factors

Abiotic and biotic factors

Divide into groups

Make two lists on a piece of paper at the top abiotic and biotic

Go outside and find as many abiotic factors and biotic factors and write on the list


Abiotic vs biotic factors

Abiotic vs. biotic factors

Draw a line to divide the poster in half and label one side biotic and the other side abiotic

Cut out magazine pictures or make drawings to list different abiotic and biotic factors


Ecosystem

ecosystem

  • Can be very small such as a pile of leaves or large such as the biosphere


Biosphere

Biosphere

  • Consists of all the land and water on earth as well as the atmosphere

  • Largest ecosystem on earth


Ecosystems vocab visuals p 731 glossary

Ecosystems – vocab visuals – p. 731 glossary


Niche

niche

  • The role of an organism in its ecosystem

  • What niche can a rotting log play in an ecosystem?


Limiting factors

Limiting factors

  • Anything that can restrict the size of a populaiton, including living and nonliving features of an ecosystem, such as predators or drought


Limiting factor activity

Limiting factor activity

  • Bear habitat activity


Limiting factor activity1

Limiting factor activity

  • Bird activity with clips, beans, corn kernels, marbles


Bell ringer2

  • In a meadow ecosystem, hawks feed mostly on mice. When the mice population is small, there is less food for hawks, so the hawk population becomes smaller. When the mice population becomes smaller. When the mice population grows. The number of hawks also grows. For the hawk population, the number of mice in this meadow is an example of a

  • A. Niche

  • B. Habitat

  • C. Producer

  • D. Limiting factor


Community and population

Community and population

  • community- all the populations that live in an ecosystem

  • Population-a group of the same type of organisms living in the same place at the same time


Population

population

  • What kind of populations will you find in a forest ecosystem?

  • Text virtual lab

  • http://glencoe.mcgraw-hill.com/sites/0078778069/student_view0/unit6/chapter21/virtual_lab.html

    Match organisms to their role in a food chain / web


Food web

Food web

  • Overlapping food chains in an ecosystem

  • Remove one organism- the consumers that eat the removed organism will decrease, the organism that is eaten by the removed organism will increase
