Organisms And Environments Review

Front 1

Producer

Back 1

Makes its own food

example: grass

Front 2

Consumer

Back 2

gets food from other organisms

example: cow

Front 3

Predator

Back 3

hunts animals for food

example: lion

Front 4

prey

Back 4

hunted for food

example: zebra

Front 5

decomposer

Back 5

gets food from dead organisms or the waste of organisms

example: mushroom (fungus)

Front 6

parasite

Back 6

receives benefits from the organism that it lives in, with, or on

example: flea, tick, leech, nematode, parasitic wasp

Front 7

host

Back 7

provides benefits to a parasite resulting in harm to itself

ex: dog

Front 8

photosynthesis

Back 8

plant's leaves and stems make sugars and release oxygen by using the Sun's energy, carbon dioxide and water

Front 9

Ecosystem

Back 9

mix of all biotic (living) and abiotic (non-living) things, conditions, and interactions in an area; organisms and populations depend on and may compete for resources and are affected by other factors (like temperature and humidity) within the ecosystem

Front 10

Run-off

Back 10

rain water containing soil contaminated with fertilizers reachers the ocean; the build up of soil destroys coral reef habitats; the nutrients in the runoff affect oxygen levels and change the ocean's ecosystem, resulting in fish deaths

Front 11

artificial reefs

Back 11

sunken human-created structures (like old trucks, boats, or bridges) provide a home for marine life like corals and sponges

Front 12

Overfishing

Back 12

humans remove fish until that species' population is greatly reduced or even eliminated

Front 13

Biotic factors

Back 13

LIVING factors in the environment

plants, animals, fungi

Front 14

Abiotic factors

Back 14

NON LIVING factors in the environment

soil, sun, water

Front 15

Herbivore

Back 15

An organism that eats only plants

ex: giraffe

Front 16

Carnivore

Back 16

An organism that eats other animals

ex: tiger

Front 17

Omnivore

Back 17

An organism that eats both plants and animals

ex: bear

Front 18

Aquatic Ecosystem

Back 18

An ecosystem that is located in bodies of water.

Front 19

Terrestrial Ecosystem

Back 19

An ecosystem that is found on land.

Front 20

Marine Ecosystem

Back 20

An ecosystem found in oceans, seas, and gulfs where the water has a salt content.

Front 21

Freshwater Ecosystem

Back 21

An ecosystem found in streams, lakes and rivers

Front 22

Autotroph

Back 22

An organism that obtains its nutrition from simple, inorganic compounds.

Ex. Producers

Front 23

Heterotroph

Back 23

An organism that must use other organisms for food, such as animals.

Front 24

Competition

Back 24

When more than one individual or population in an ecosystem relies on the same resource.

(water, food, space, shelter)
