SCIENCE TEST UNIT 2

Define Organism TEST

single living member of a species

what is a population *******TEST

all members of a single species in the ecosystem

Whats a niche******TEST

WAY OF LIVING in a habitat

What is a carrying capacity********

MAXIMUM # of organisms in a species that

can SUSTAIN INDEFINITELY

What is exponential growth*

MAXIMUM RATE that population increases with

UNLIMITED RESOURCES

What is the definition of Ecology

1. Study of nonliving and living things

2. or you can say study of ECOSYSTEMS OF THE EARTH

what does Eco or Oiko mean

HOME

What is an ecosystem

AREA where plants and animals interact with each other AND THEIR ENVIRONMENT

What is a biosphere?

All of earth’s ecosystems

What is a factor?

Part of something

What is logistic Growth?*

SLLLOOOW down of growth due to LIMITED resources/competition

What is the term for limited resouces and competition? (2 words!)

Environmental resistance

What is POPULATION GROWTH?*

When an organism enters a new environment it tries to make copies of itself

What are living things called?

Biotic factors

What are nonliving things called?

Abiotic factors

Name 5 biotic factors

1 plants

2 animals

3 bacteria

4 fungus

5 protists

Name 5 abiotic factors

1 Sunlight

2 air

3 water

4 soil

5 minerals

What is an abiotic factor that makes it so that ecosystems can’t survive?

POLLUTION can DESTROY an ecosystem to make it impossible to live there

What is an abiotic factor is recycleable

water

T/F is Wind is abiotic

True

T/F elevation is abiotic

True

T/F temperature is abiotic

True

T/F latitude is abiotic

True

T/F climate is abiotic

False

T/F Calista is so amazing :)

TRUE

Can exponential growth go on forever?

Yes

What are the limits of an ecosystem?

1 The amount of resources available

2. The population size

3. The amount of resources each organism is consuming

Why can’t exponential growth go on ?

Limited resources causes the growth to slow down

Name 3 things that make up life

ICE

• Instructions (follows instructions inside itself)

• Copies of itself

• Energy it takes in

What is the rank size small to big

Organism > Population> Community> Ecosystem>Biosphere

FILL IN. A habitat is a place where an _________ lives TEST

organism

Give me an example of a niche

Warbler bird, cape may, bay breast, yellow rump live in different parts of the tree

T/F Is Livi great

True

T/F Is Mom hahaha

hahaha

T/F is Dad hehehe

heheHA!

T/F Is Maddie SUPER CUTE!!!

TRUE!!!!!!!!

T/F Is Camille SUPER CUTE!!!

TRUE!!!!!!!!

What is TROPHIC LEVEL?

A feeding level in ecosystem

What is the LAST trophic level?

It is BACTERIA as a decomposer

T/F does a food chain show how matter and energy move through the ecosystem

True

T/F Does energy transfer from the first to second to 3rd to 4th trophic level?

True

T/F Does an organism’s metabolism and as heat lose energy as kcals or calories or kcal/m2?

True

Is a food web more realistic than a food chain? Why?

Yess because the web is a network of connected food chains, and its more realistic because organisms feed on more than 1 species for food

WHAT IS A COMMUNITY? TEST

COMMUNITY-all living things in ecosystem

what is a habitat TEST

place where an organism lives

What are 4 things a Habitat provides? TEST

*4 things habitat provide:1 food/water for energy/nutrients

2 shelter for safety 3 livable environment, 4 space to reproduce

HOW IS EXPONENTIAL GROWTH DIFFERENT THAN Logistic growtth? TEST

different growth curves, limited vs unlimited resources

What is the difference between density dependent vs independent factors?

Density dependent factors like food/water,disease,predators-limit pop.

Density Independent natural disasters

What is the definition of density?

amount of stuff in a space

what is a claim vs evidence vs reasoning

claim is answer to the question, evidence is quantitative observations, and reasoning is why the evidence supports the claim

formula for F to C , and C to F

F-32 x 5/9 ; Cx9/5 add 32

are moose and wolf populations affected? Why is it important for us to study?

Linked and more moose more wolves etc , helps us see our actions impacting our world

what organization is it? Insect fish anad algae in lake"?

A tree frog?

An ocean?

A bat group in a cave

fish and alge and insecs is a community

frog is organism

ocean is ecosystem

bats in a cave is a population

whats the difference between biosphere and biome

biosphere is Earth and ALL systems, biome is a specific ecosystem with the SAME clomate and similar communities

what is a biotic

living part of the environment

same species same area is a

POPULATION

What is a niche vs habitat?? TEST

How organism goes about gathering its resources

habitat is just the place in the ecosystem where it lives

if 2 organims try to live in same niche in the same habitat what would happen?

one would force the other to starve or leave the area

TF are limiting factors closely tied to carrying capacity?

True

What happens if too many species in ecosystem

stress, starvation disease predation and damage to habitat

what is it called when there is an increase in number and may be a temporary exceed in carrying capacity

Overshoot

what is a limiting factor?

Factor that controls the growth of a population

What is CER?

claim , evidence, reasoning

What is symbiosis

2 DIFFERENT species living together

whats mutualism

2 different species living together and they both benefit

does a parasite kill the other organism?

no, A parasite FEEDS on it but usually doesnt kill it

what is parasitism

relationsship where 1 organism benefits and the other is harmed

what is commensalism

2 different species live togehter, 1 benefits and 1 doesnt care

what is an equillibrium?

balance

what is a predator prey relationship?

eaten and eat

what is the difference between autotroph vs heterotroph

autotroph self feeding and makes its own food, producers like plants, heterotrophs do not make own food

what does biomass mean

total energy/matter including plants animals microbes in an area

wahts the 10% law

TRANSFER-energy from 1 trophic level to the next =10% LAW

what are words to describe the food chain? bottom to top

prim…quaternary

as energy passes through food is energy loss

yes energy is loss (by HEAT during the organism’s metabolism); measured in KCAL and overall kcal/m2/year

are there more producers than all consumers combined?

yes

is a secondary consumer an omnivore?

yes

what is conservation?

protection of resources

can 2 species. share the same habitat but not the same niche?

yes

is salt water and fresh water part of the biosphere?

yes. Along with air and land

are phytoplankton producers? what are kelp?

yes, phytoplankton are kelp are primary producers

are zooplankton herbivore THEY ARE HETEROTROPIC

yes
