Q

The variety of important biological
and chemical processes occuring
in ecosystems .

A

functional diversity

24
refers to variety of life forms and the number of each species present in a biological community
species diversity
24
refers to the total variety of genes or inheritable characteristics present in a population of organisms.
genetic diversity
25
number of different kinds of species in a particular area
species richness
26
is a set of inviduals that have the same distinct characteristics and are able to mate and produce fertile offspring.
species
27
refers to the variety of ecosystems in biosphere. Climate and amount of sunlight help organisms to adapt to a particular habitat.
ecosystem diversity
28
refers to the biological and chemical processes that includes energy flow,biogeochemical or nutrient cycles, and interactions of organisms, which are important for the survival of species, populations, communities and the entire ecosystems.
functional diversity
29
types of interaction
competition predation symbiosis (commensalism,mutualism,parasitism)
30
Organism of different species that live near one another strive to obtain the same limited resources
competition
31
An organism of one species kills and eats an organism of another
predation
32
Two or more organisms of different species live together in close association over a prolonged time
symbiosis
33
One species benefits and the other species neither benefits nor harmed
commensalism
34
Both particular species benefit
mutualism
34
One species benefits but the other is harmed
parasitism
35
survival of living things
population organism ecology community
36
Is a group of interactive organism of the same species that live in a particular area.
population
37
Is a sub-branched of Biology that deals with the study of the interaction of living organisms (biotic) to its environment (abiotic).
ecology
38
Is an individual form of life that is capable of growing and reproducing, and have one or more cells.
organism
39
The various populations of different species interacting with one another in area.
community
40
is a collection of creatures of the same type.
population
41
provide food
economic value
41
struggle between organisms
competition
41
It’s a living being's tendency to adapt
natural section
42
value of biodiversity
ecological value moral and ethical value economic value
43
depend on each other for survival
ecological value
44
total disappearance
extinction
45
gradual process of becoming extinct.
background extinction
45
when a certain population of organisms cease to exist in a geographic area
local extinction
46
species that are risk of extinction
endangered species
47
could become endangered
threatened species
48
Extinction of the dinosaurs
Cretaceous-Tertiary Period Mass Extinction
49
Half of all the species including large amphibians become extinct.
Triassic-Jurassic Period Mass Extinction
50
Also known as the Great Dying
Permian Period Mass Extinction
51
Three quarter of all species on Earth died.
devonian period mass extinction
52
Third largest extinction in Earth’s history
Ordovician-Silurian Mass Extinction
