Answer 1

the study of the relationship between 2 organisms and an organism and its enviorment

Question 2

Answer 2

be composed of one or more cells

contain either dna or rna as their genetic material

be capable or growth

be capable of reproduction

demonstrate the ability to respond to outside stimuli

as a popul. be able to adapt to the environment and evolve

have metabolism

Question 3

reproduction can be what and define

Answer 3

sexual: 2 parents produce genetically unique offspring together

asexual: 1 parent produces genetically identical offspring

Question 4

stimulus

Answer 4

a change in an organism’s environment (change)
how an organism reacts to a change in its environment (effect)

Question 5

Metabolism

Answer 5

all of the chemical reactions of each cell in an organism that provides energy for life’s processes and create key molecules

Question 6

venn diagram on photosynthesis. vs. chemosynthesis

Answer 6

photo: source of energy from sun
Chemosynthesis: source of energy is chemicals
Middle: use non-living sources for energy

Question 7

Organism

Answer 7

individual member of a species are population example one deer

Question 8

Population

Answer 8

multiple organisms of the same species living together

Question 9

Community

Answer 9

multiple populations of different species living together

Question 10

Ecosystem

Answer 10

Community plus all the abiotic factors in the environment

Question 11

Biome

Answer 11

multiple ecosystems that share similar characteristics but are located in different parts of the planet

Question 12

Biosphere

Answer 12

the zone of life on Earth encompassing all of the Earth’s ecosystems

Question 13

Biodiversity

Answer 13

the variety of organisms considered all levels from populations to ecosystems

Question 14

binomial nomenclature

Answer 14

to name naming system that names organisms after their genus species

Question 15

abiotic

Answer 15

non-living

Question 16

Biotic

Answer 16

living

Question 17

Producers

Answer 17

autotrophs

Question 18

autotrophs

Answer 18

Producers

Question 19

Where and when do producers get their energy from?

Answer 19

from non-living sources most capture energy during photosynthesis to make simple sugars

Question 20

Consumers

Answer 20

heterotrophs

Question 21

heterotrophs

Answer 21

Consumers

Question 22

where do heterotrophs get their energy from

Answer 22

living or once living organisms

Question 23

Consumers eat other organisms to get energy then they break what and why

Answer 23

Macromolecules inside of them to release ATP in cellular respiration

Question 24

Herbivores

Answer 24

Eat only vegetation

Question 25

Omnivores

Answer 25

eat meat and vegetation

Question 26

Carnivores

Answer 26

eat only meat

Question 27

detritivores

Answer 27

eat dead materials

Question 28

Food chain

Answer 28

traces a single flow of energy and show trophic levels which are the levels of nourishment in the food chain

Question 29

Rule of 10

Answer 29

as energy flows from organism to organism the energy is used for metabolism or converted to heat

because of this the next organism on a food chain only receives 10% of the energy
obtained in the previous level thus the other 90% is used or lost as heat

Question 30

energy flow name wise

Answer 30

producers, primary consumers, secondary consumers, tertiary consumers

Question 31

food web

Answer 31

shows multiple food chains at once and how they interconnect

Question 32

Trophic pyramids

Answer 32

models that show how energy flows through an ecosystem

Question 33

energy pyramid

Answer 33

represents the energy available at each traffic level, levels always get smaller as you go up the pyramid

Question 34

Numbers pyramid

Answer 34

represents the number of organisms at each trophic level since energy decreases as you go up the pyramid, fewer organisms can be supported

Question 35

Biomass pyramid

Answer 35

represents the total mass of living organic material of each trophic level
