25
omnivore is
they eat both plants and meat
26
Detritivores
are animals that feed on detritus (dead organic material) through internal digestion
27
Decomposers are
responsible for basically eating up the dead organisms chemicals and are consumers
28
Intraspecific Competition
Competition between members of the same species
29
numbers of the same species could compete for..
Territories Shelter Mates Food and water Nesting sites
30
Interspecific Competition
competition between different species
31
REMEMBER:
Populations of Prey & Predators go in cycles
32
Parasitism
a relationship where one organism benefits and the other one dosent ( mosquitoes and humans )
33
commensalism
a relationship where one organism benefits and the one is unaffected ( bird and tree )
34
mutalism
a relationship where both organisms benefit ( whale shark and remora )
35
sym=together bio=Living so symboisis..
living togteher
36
JUST REMEMBER
Symbiosis is a close and often long-term relationship between two or more species
37
adaptions
structural, behavioural or physiological characteristics that allow an organism to survive and reproduce in their environment.
38
structual adaption..
features of organism body like shape or colour
39
behavourial adaption..
ways organisms behave that increase their chances of survival e.g., migration, courtship rituals
40
Physiological
Things that go on inside an organism body related to chemical processes e.g. hibernation, colour-changing
41
verterbrete claasses:
amphibia, pices, reptilla, aves,mammalia
42
the two domains are
prokanyotes and eukanyotes
43
5 kindoms are
bacteria, animal, plant, fungi, protists
44
what is an endotherm
they have to maintain an internal body tempreture and generate their own heat ( so they ccan be warm in cold places )
45
what is an ectotherm
they do not maintain constant body temp and they have to adapt and go to places to get the heat or cold they want ( like the sun or shade)
46
an apex predator is
the animal at the top of the food chain that has no natural enimies
47
cellular respiration is made by
oxygen + glucose = carbon dioxide + water + energy
48
photosynthesis is made by
carbon dioxide + water + energy = oxygen + glucose
49
monera is
bacteria
50
bacteria factors
no nucleus, has a cell wall/capsule, no chloroplasts, unicellular
51
protists factors
has a nucleus, no cell wall, chloroplasts and is unicellular ( mostly )
52
fungi factors
has a nucleus, cell wall, no chloroplasts, is multicellular and unicellular
53
plants factors
has a nucleus, cell wall, chloroplatss, multicellular
54
animal factors
has a nucleus, no cell wall, no chloroplats and is multicellular
55
biotic and abiotic factors
Biotic factors are living things in an ecosystem (such as plants, animals, and bacteria), while abiotic are non-living components; (such as water, soil and atmosphere)
56
detrtivore
an organism (such as an earthworm or a fungus) that feeds on dead and decomposing organic matter.
57
heterotroph's and autotrophs
Autotrophs are organisms that can make their own food. heterotrophs depend on autotrophs and other organisms for nutrition. ( like the tree and strangler fig )
58
trphic levels
the number of steps from the start of the food chain
59
monotremes reproductive system
lay eggs
60
marsupials reproductive system
undeveloped thing that climbs into the pouch
61
placental reproductive system
nourish baby iside mothers body by placenta
62
bird reprpoductive system
lay hard shell egg
63
mammals repproductive system
give birth normally and feed with milk
64
amphibians reproductive system
lay eggs without shell underwater
65
fish reproductive system
lay eggs without shell under water
66
reptile reproductive systme
