Ch.9 Section 2-3

Front 1

Producer

Back 1

use photosynthesis to turn sunlight into food

Example: Grass takes sunlight and turns it into food

Front 2

Herbivores

Back 2

eat producers because the can't make their own food Example: cows eat grass only

Front 3

Carnivores

Back 3

eat meat/herbivores and omnivores

Example: Foxes eat cows and other meat only

Front 4

Omnivore

Back 4

eat both plants and meat

Example: Humans eat meat and fruits

Front 5

Consumer

Back 5

Can't make their own food so eat other things

Example: all animals that are alive

Front 6

Detritivore

Back 6

eat dead plants or animals and break down materials to be used in other things

Example: Worms and insects eat rotten apples

Front 7

Food Chain

Back 7

models how energy flows in an ecosystem through feeding relationships

Example:grasshoper eats a plant the mouse eats the grasshopper & the snake eats the mouse

Front 8

Food Web

Back 8

a model that shows several connected food chains Example: a rabbit eats a plant and a coyote eats the rabbit the coyote also eats the chipmunks

Front 9

Energy Pyramid

Back 9

show the amount of energy available at each step of a food chain Example: Producers 100% Primary 10% Secondary 1% Third 0.1% Fourth 0.01%

Front 10

Oxygen Cycle

Back 10

Example: 6Co2 + 6H2O + energy -> C6 H12 O6 + 6 O2

Front 11

Carbon Cycle

Back 11

CO2 + H2O + light => C6H12O6 + energy or fuel + oxygen -> heat + water + Carbon Dioxide

Front 12

Photosynthesis

Back 12

the way plants get their food -6Co2 + 6H2O reactants -> 6O2 + C6H2O2 Products

Front 13

Population

Back 13

made up of all the members of one species that live in an area

Front 14

Community

Back 14

all populations living in an ecosystem at the same time

Front 15

limiting factors

Back 15

are factors that can limit the growth of a population Example: predators, disease

Front 16

Biotic Potential

Back 16

the potential growth of a population if it could grow in perfect conditions with no limiting factors

Front 17

Carrying Capacity

Back 17

The largest number of individuals of one species that an ecosystem can support over time

Front 18

Habitat

Back 18

the physical place where a population or organism lives

Front 19

Niche

Back 19

the unique way an organism survives ,obtains food and shelter, and avoid danger in its habiat

Front 20

Symbolic Relationship

Back 20

one in which two different species live together and interact closely over a long period of time

Front 21

Population Size

Back 21

can increase or decrease

Front 22

Population Density

Back 22

describes the number of organisms in a population relative to the amount of space available

Front 23

Overpopulation

Back 23

A population becomes larger than an ecosystem's carrying capacity

Front 24

Mutualism

Back 24

a Symbolic Relationship in which two species in a community benefit from the relationship Example:

Front 25

Parasitism

Back 25

a symbolic relationship in which one species (the parasite) benefits while another (the host) is harmed Example a tick in a dog

Front 26

Commensalism

Back 26

a symbolic relationship where one species benefits and the other is neither helped or harmed Example:barnacles on whales stomachs

Front 27

Prey

Back 27

an animal hunted or seized for food especially by carnivores

Front 28

Predator

Back 28

any organism that exist by preying upon other orginisms
