what are producers?

producers produce substances like food, nutrients and oxygen. they are a primary component of an ecosystem . an example of a producer would be plants

plants

what are consumers

consumers consume things generated by producers. an example of a consumer would be animals

animals

what is the population equation?

dN/dt=rN

biomes in canada

artic tundra, which is found in northern parts of canada


boreal forest, which is the largest vegetative region in canada


temperature rain forest, which costal regions have mild climate with abundant precipitation


short grass prairie- the growing season is warm and dry


long grass prairie- ideal for agriculture

biome definition

a forest of tundra , a large community of fiora and fauna occupying major habitats

on the periodic table , where are the metals and non metals located

non metals are on the far right corner except for hydrogen, which is on the opposite side. metals are found on the left of the stair line .

electricity force is

amount of charge that has the ability to change the motion of one or both objects

induced charging

the separation of charges on an object due to the presence of another

charging by friction

a transfer in electrons when two objects rub together

conductor

a marital that permits flow of energy

insulator

a material or object that does not easily allow heat

load

the comportion or portion used in a circuit the consumes power

swich

removes or restores the conducting path in a circuit

parelle circuit

closed circuit in which the current goes in 2 or more paths

population size

definition

what are periods on the periodic table ?

the periods are numbered 1 to 7 on the left side of the table

what are collums on the periodic table ?

each collum is a group that has the same number of elections in the outer orbital called valence elections

what is a chemical reaction?

it’s a process that involves rearrangement of the molecular or ionic structure changes in physical form or nuclear reaction

how are ions formed?

when atoms loose electrons or gain elections . metal atoms form positive ions . non metal atoms form negative ions.

finding protons / nutrons

subtract the atomic number from the atomic mass

what is static electricity

an electric charge usually produced my friction that causes sparks and crackling

physical change

cutting up a peice of paper would be a physical change . physical changes can be reversed

what is a chemical change

chemical changes cannot be reversed , a chemical change would be old milk, bread to toast and rust forming on a nail

population size definition

the number of individuals in a population

population density

population size per unit area

population abundance

refers to the relative representation of a species in a particular ecosystem

cellular respiration’s word equation

glucose+oxygen —> carbon +water + energy

photosynthesis number equation

6CO2+6H20–> sunlight energy +C6H12O6+602

what’s glucose ?

C6H12O6

what’s 6H2O?

water

what’s carbon?

6CO2

what’s 6O2?ab

oxygen

tundra

relating to or resulting from living things , especially the ecological relations

abiotic

physical rather than biological , not dependant from living organisms

tundra

a vast , flat treeless artic region

natiility

the ratio number of births to the size of the population-birth rate

mortiallity

the number of deaths in a givin area

e

the action of coming to live permanently in a country

l

the act of leaving ones country to settle peremintly in another

exponential growth

growth whose rate become more rapid in proportion to the growing total number of size

limiting factors

environmental conditions that limit growth abundance of distribution of an organism or population of one in an ecosystem

what’s photosynthesis word equation

carbon dixiodie +water +sunlight energy +glucose + oxygen

what is cellular respiration number equation

C6H12O6 + 6O2-> 6CO+6H2O+ATP
