Question 10

habitat

Answer 10

conditions required for the survival of a species
ex: ocean, rainforest, desert

Question 11

UV Radiation

Answer 11

reveals how much time to spend in the sun on a specific day

Question 12

biodiversity

Answer 12

number of species in an ecosystem and the variety

Question 13

why the frog?

Answer 13

health of frogs shows the health of the ecosystem
insect populations would increase
malaria

Question 14

are wolves bad?

Answer 14

no, when wolves disappear there are more coyotes
bigger animals left without food source

Answer 15

no, its detritus

Answer 16

organism that people consider harmful/inconvenient
ex: weeds, some insects, rodents

Question 17

ecology

Answer 17

study of the interaction of living things with each other and with abiotic factors in their environment

Question 18

abiotic

Answer 18

non-living things that factor in an ecosystem
ex: sunlight, temperature, strength/ direction of wind

Question 19

Biotic

Answer 19

factor in an ecosystem by the presence and role of living things
ex: plants, animals

Question 20

population

Answer 20

all the members of a species living in the same ecosystem or habitat

Question 21

community

Answer 21

collection of all the populations of all species in an ecosystem

Question 22

ecotone

Answer 22

the transition area between 2 ecosystems, includes members of the community of both ecosystems

Question 23

yes invasive species

Question 26

photosynthesis

Answer 26

plants and other organisims use sunlight energy and carbon dioxide and water to produce sugar and oxygen

Question 27

albedo effect

Answer 27

measurement of the percentage of light that an object reflects (higher the albedo greater the object’s ability to reflect sunlight)

Question 28

autotrophs

Answer 28

organism that uses energy and raw materials to make food, instead of photosynthesis
ex: algae, grass, wheat

Question 29

primary consumers

Answer 29

organism that survives on autotrophs for energy source (second trophic level)
ex: flies, rabbits

Question 30

secondary consumers

Answer 30

organism that relies on primary consumers for energy source ( third trophic level)
ex: carnivores, frogs, fish

Question 31

heterotrophs

Answer 31

incapable of making its own food, feeds on other organisms to gain energy
ex: humans, bacteria, fungi

Question 32

food web

Answer 32

representation of the feeding relationships or organisms in an ecosystem

Question 33

biome

Answer 33

collection of ecosystems that are similar or related to each other in that the dominant form of plant is the same
ex: boreal forest biome is dominated by coniferous trees

Question 34

physical adaptations

Answer 34

feature of an animal that helps them survive better in their environment
ex: shape of a bird beak, colour of a animals fur

Question 35
