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 glossary

  • Living parts of the ecosystem

  • Also, those things that were once living

  • Plants, animals, bacteria

Abiotic glossary

  • 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?” glossaryAbiotic 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 glossary

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

a.rocksc.sea horse


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



Bell ringer1
Bell ringer glossary

  • 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 glossary

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 glossary

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 glossary

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

Biosphere glossary

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

  • Largest ecosystem on earth

niche glossary

  • The role of an organism in its ecosystem

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

Limiting factors
Limiting factors glossary

  • 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 glossary

  • Bear habitat activity

Limiting factor activity1
Limiting factor activity glossary

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

Bell ringer2
Bell ringer glossary

  • 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 glossary

  • 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 glossary

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

Population glossary

  • Brain pop movie clip: “Population growth”



Bell ringer3
Bell ringer glossary

What was the approximate population density of the prey population in April and May?

A) 8 B) 12 C) 10 D) 14 3

In which month was the prey population the lowest?

A) April B) November C) February D) December

Bell ringer4

  • During which season did the rose insect population grow the fastest?

  • A) spring B) summer C) fall D) winter

Ecosystem video
Ecosystem video glossary


  • Biology: The Science of Life: Ecology: Organisms in Their Environment

Ecosystems video
Ecosystems video glossary

  • Brain pop video on “ecosystems’”


  • Video discusses ecosystems, habitats, communities, populations

Ecosystem video1
Ecosystem video glossary

  • Give 3 examples of decomposers, producers, and consumers in the video

Virtual lab food chain
Virtual lab-food chain glossary

  • Text virtual lab


    Match organisms to their role in a food chain / web

Food web
Food web glossary

  • 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

Food web1
Food web glossary

Food web2
Food web glossary

  • Example:

  • Grass mice snake hawk

    Analyze the food chain above and describe what would happen if you removed one organism

Food web3
Food web glossary
