Q

Heterotrophs

A

Organisms that ingest or absorb food in the form of organic material from their environment also known as consumers

Q

Mid ocean ridges

A

Series of ridges and mounts located on the ocean floor

32
Q

Mimicry

A

A situation in which one species has an appearance similar to that of a different but distasteful species where that similarly apparently gives protection and predators

33
Q

Muatalism

A

An association between two different species in a community in which both gain some benefit

34
Q

Mycorrhiza

A

Fine threads formed by a fungus that for a large surface area for a large uptake of ingredients

35
Q

Niche overlap

A

Situation in an ecosystem in which different species are in competition for the same energy and space resources, niche overlap in ecosystems is normally zero

36
Q

Niche seperation

A

Situation in which two species in the community use different resources Such that the two species have no degree of niche overlap

37
Q

Nitrogen fixing bacteria

A

Bacteria able to convert nitrogen from the atmosphere into ammonium ions

38
Q

Omnivores

A

Organisms that eat both plants and animals

39
Q

Parasite

A

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

40
Q

Parasite host relationship

A

Form of interaction within a community that involves one species the parasite living in or in another species the host typically without killing the host

41
Q

Parasitoids

A

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

42
Q

Pheromones

A

Chemicals secreted by some animals to communicate with other memebers of the species, chemical messengers

43
Q

Photsynthesis

A

Process by which plants trap the radiant energy of sunlight and turn it into carbohydrates and carbon dioxide and water

44
Q

Pioneer species

Q

Predator

A

A form of interaction within a community that involves the eating of one species the prey by another species the predator

48
Q

Prey

A

Living animal that is captured and eaten by the predator

49
Q

Primary succession

A

Ecological succession occurring in an area that was not previously colonised

50
Q

Producers

A

Photosynthetic organisms and chemo synthetic bacteria that given a source of energy can build organic matter from simple inorganic substances

51
Q

Secondary succession

A

Establishment over time of replacement communities in an area following an event that removes the original community

52
Q

Succession

A

Natural process by which the community living in an area changes over time

53
Q

Sulfur bacteria

A

One group of bacteria that gain energy by oxidising Sulfur compounds

54
Q

Symbiosis

Prolonged association between different species in a community in which at least one partner benefits including parasitism mutualism and commensalism

Q

Volatile

A

Refers to a chemical substance that vaporises at ambient temperatures and diffuses through the air

56
Q

Warning coloration

A

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