organism that can make food for itself and store some food for another organism

Question 3

Autotroph

Answer 3

organisms that capture sunlight/energy to make its own food

Question 4

Consumer

Answer 4

organisms that rely on other organisms for energy and nutrients

Question 5

Heterotroph

Answer 5

organisms that require energy from other organisms

Question 6

Decomposer

Answer 6

organism that chemically breaks down dead remains into detritus

(and recycles the nutrients back into the environment)

Question 7

Detritivore

Answer 7

animals that commonly digest decomposers that live on, and in, detritus particles

(eats detritus particles)

Question 8

Scavengers

Answer 8

animal that consumes the carcasses of other animals that have been killed by predators or have died of other causes

consumer that only eats other animals

Question 11

Omnivore

Answer 11

animals whose diests include plants and animals

Question 12

Food Web

Answer 12

a network of feeding interactions that depict the complex feeding relationships in ecosystems

Question 13

Food Webs link together many ____ _____

Answer 13

food chains

Question 14

Where is energy stored?

Answer 14

in body tissues

Question 15

How does energy move between organisms?

Answer 15

from the “eaten” to the “eater”

Question 16

Ecological Pyramids

Answer 16

pyramids that show the relative amount of energy or matter contained within each trophic level in a given food chain

Question 17

Types of ecological pyramids

Answer 17

pyramids of energy, pyramids of biomass, and pyramids of numbers

Question 18

Energy Pyramid

Answer 18

pyramids that show the relative amount of energy contained within each trophic level in a given food chain

Question 19

Trophic Levels

Answer 19

steps in a food chain or food web

Question 20

The 10% Rule

Answer 20

10% of the energy available within one trophic level is transferred to the next trophic level

Question 21

Photosynthesis

Answer 21

process that plants do by using resources from the environment to create food

Question 22

Balanced Chemical Equation For Photosynthesis

Answer 22

6H2O + 6CO2 –(light)-> C6H12O6 + 6O2

Question 23

Where/what do plants store polysaccharides as?

Answer 23

in the tissues/as starch

Question 24

Types of Human Interference Disturbance Impacts

Answer 24

pollution and overharvesting

Question 25

Pollution results in…

Answer 25

bioaccumulation/biomagnification

Question 26

Bioaccumulation/Biomagnification

Answer 26

when a pollutant is picked up by an organism and is not broken down or eliminated, and it is collected in the body tissues instead

as producers are eaten and the organisms of trophic levels becomes higher, the more concentrated the pollutant becomes

Question 27

Disturbance Impacts

Answer 27

phenomenons that occur and change the natural way of a food web

Question 28

Overharvesting

Answer 28

when humans overdo something and kill of a majority of a species

Question 29

Disease (in terms of Disturbance Impacts)

Answer 29

naturally occurring sickness that wipes out a majority of a species’ population

Question 30

Introduced Species (in terms of Disturbance Impacts)

Answer 30

a new species being added that increases competition with the already present species

Question 31

Climate change (in terms of Disturbance Impacts)

Answer 31

changes in the climate that can severely alter the landscape

causes loss of habitat

Question 32

Invasive Species

Answer 32

species that are foreign to the environment that dominate the area and becomes harmful to environment

(as a result of introduced species that don’t have a predator in the area)

Question 33

Ecosystems that have greater biodiversity are said to be more resilient. Why?

Answer 33

more biodiversity increases the amount of organisms that can be preyed on

If a majority of one species is wiped out, there will still be more food sources that keep the food web stable
