Back 1

Substances produced by plant that prevent or limit damage by herbivores.

Front 2

Camouflage

Back 2

Structural method of protection against predartors in which the appearance of an animal.

Front 3

Commensalism

Back 3

Association between teo different species in a community in which one benefits and the second apparently neither gains nor is harmed.

Front 4

Consumers

Back 4

Organisms that obtain their energy and organic matter by eating or ingesting the organic matter of other organisms; also termed heterotrophs.

Front 5

Detritivores

Back 5

Organisms that eat particles of organic matter found in soil or water.

Front 6

Diversity

Back 6

Measure of 'species richness'or the number of different species in a community.

Front 7

Ecology

Back 7

Study of communities in their habitats and the interactions between them and their enviroment

Front 8

Endoparasites

Back 8

Organisms that live inside another organism and obtain food ffrom it, such as a tapeworm.

Front 9

Guilds

Back 9

Groups of different species that use similar food resources in a similar way in an ecosystem, such as see-eating birds.

Front 10

Haustoria

Back 10

thin strand of tissue through wich a plant parasite makes connection with its host.

Front 11

Herbivore- Plant relationship

Back 11

Organisms that eat living plants or parts of them.

Front 12

Holo-Parasitism

Back 12

Form of parasitism in which a plant parasite depends completely on its host for nutrients and water.

Front 13

Mid-Ocean Ridges

Back 13

Series of ridges and mounts location on the ocean floor.

Front 14

Niche Overlap

Back 14

Situation in an ecosystems in which different spiecies are in competition for the same energy and space resources.

Front 15

Nitrogen-fixing becteria

Back 15

Bacteria able to convert nitrogen from the atmosphere into ammonium ions.

Front 16

Parasite

Back 16

Oranism that lives on or in another organism and feeds from it usually without killing it.

Front 17

Parasitoids

Back 17

Adult females of some wasp and fly species that are like parasites but that slowly kill their hosts.

Front 18

Population

Back 18

Membersof one species living in a specific habitats at a particular time.

Front 19

Predator-Pray

Back 19

A form of interaction within a community that involes that eating of one species, the pray, by anouther species, the predator.

Front 20

Sulfur Bacteria

Back 20

One group of bacteria that gain their energy by oxidising sulfur compounds.

Front 21

Warning Colouration

Back 21

Bright pattern of colour markings on a species that apparently signals to predators that the members of the species contains distasteful chemicals.
