Standard 5 Identifying cells, tissues, organs, organ

1
Identifying cells, tissues, organs, organ
systems, organisms, populations, communities, and
ecosystems as levels of organization in the
biosphere.
Standard 5

• Aaron Sahmod

2
The following slides explain the levels of
organization from Cells to Biospheres
3
Cells

• A structural unit of all living things. The
  smallest unit classified as an living organism.

4
Tissues

• Tissues are an ensemble of cells, they are not
  the same but the are of the same origin, that
  carries out an function.

5
Organs

• Organs are groups of tissue that perform
  different functions. There are many organs in the
  body like skin, kidney, liver, and etc.

6
Organ Systems

• Some types of organ systems are, Circulatory,
  Respiratory, Digestive, Nervous, and Reproductive.

7
Organism

• A single living organism. Example Humans, Cows,
  Birds, Trees.

8
Population

• A group of organisms of one type staying in the
  same area. An example is like and herd of cows on
  a plain, or the number of people living in
  Tuscaloosa.

9
Community

• Different populations that live together.
  Examples Cows, snakes grass, hawk.
• They must all be LIVING Things
• The community below includes the horses, cows,
  chickens dogs

10
Ecosystems

• These include the living nonliving things found
  in the community (people birds water soil dogs
  etc.
• Two examples of Ecosystems are wetlands and
  forests.

11
Biosphere

• Our Biosphere is made up of all of the biomes/
  ecosystems on the planet earth.

QuestionsTest your Knowledge
13
A Pod of bottlenose dolphins living in a specific
region can be identified as which level of
organization?

• A. Biosphere
• B. Ecosystem
• C. population
• D. community

14
C population

• A population is a group of organisms of one type
  that all live in the same area.

15
Study the picture belowWhich level of
organization is BEST represented by the entire
picture?

• A. Organism
• B. ecosystem
• C. population
• D. community

16
B ecosystem

• An ecosystem is a community and its nonliving
  surroundings as labeled here

Air
Bird
Trees Bushes
Grass
Water
Alligator
Fish
17
A group of cells that work together for a common
function would MOST LIKELY be described as

• A. a tissue
• B. an organ
• C. an organelle
• D. a community

18
A. a tissue

• A tissue is a small group of cells used to make
  up organs such as the brain

19
Study the diagram below

• A. Plant
• B. Animal
• C. Biosphere
• D. community

• Which is a level of organization that could be
  represented by X?

20
D. community

• A community is larger than a population but less
  inclusive than an ecosystem

21
Study the picture below

• A. Biosphere
• B. Ecosystems
• C. Populations
• D. community

• Which level of biological organization results
  from the combination of the living organisms
  shown in the picture?

22
D. community

• A community is all living things (plants and
  animals) that live in a defined area

23
Which figure BEST represents the levels of
organization in the ocean from largest to
smallest?

• Community
• Organism
• Ecosystem
• Population

• B. ecosystem
• community
• population
• organism

C. organism population community
ecosystem
D. population ecosystem organism
community
24
B. Ecosystem, Community, Population, Organism

• Ecosystem, Community, Population, Organism is
  the levels of organization in descending order

25
Which sequence correctly identifies the levels of
organization in a biosphere from most complex to
least complex?

• A Organism?Population?Community?Ecosystem
• B ecosystem?community?population?organism
• C community?organism?ecosystem?population
• D population?ecosystem?organism?community

26
B. ecosystem?community?population?organism

• An ecosystem is a community and all its
  surroundings making it the most complex and an
  organism is one living object making it the
  simplest

27
Study the tables below. Ospreys, egrets and
cranes were observed in an area around a small
oxbow lake at Perry Lakes Park in Alabama
Which student correctly categorized the
observations according to the levels of
organization in the biosphere
A Student 1 B Student 2 C student 3 D student 4
28
C student 3

• Since an organism is a single living thing you
  have to include all of them so 638522170 and a
  population is only one type of animal and three
  birds were being studied there were 3 populations
  and since a community is all the populations
  combined there is only 1 community

29
Study the Diagram below

• Forests, animals, sunlight, soil, water
• Oak forest, grey squirrels, deer
• Oak forest
• Oak tree

Which example below represents the organizational
levels shown in the diagram?

• A Organism B ecosystem C Community
  D Population
• Population community
  Ecosystem Organism
• Community population
  Organism Ecosystem
• Ecosystem organism
  Population Community

30
B ecosystem community
population organism

• An ecosystem is a community and its nonliving
  surroundings. Communities are populations in a
  defined area. Populations are groups of
  organisms. An organism is a single living thing.

31

• Study the picture

10
Hint This includes the water ,soil, animals
trees.
Which level of organization is BEST represented
by the entire picture? This includes the water
,soil, animals trees.
A Population B Community C Ecosystem D
Organism
32

• C. Ecosystem, because it is made up of the living
  non living things.

33
11

• A scientist studied a coral reef in an ocean. The
  scientist made a data table to record what was
  observed. How many populations are represented by
  the data?

A 2 B 6 C 67 D 101
34

• The answer to that question is B. 6
• It asked how many populations, and there are 6
  populations. (Sea turtle, Sea Star, Nurse Shark,
  Clown Fish, Parrotfish, Sea urchin. Each TYPE is
  a different population.
• The population of a town is the number of people
  that live there.

35
12
Study the list of terms below.
osteocyte stomach muscle digestive system
Hint This word ends in cyte which means CELL

• A student preparing for a test in human anatomy
  studied the terms in the list. Which of the
  following represents a tissue in the human body?

A Bone Cell B Stomach C Muscle D Digestive
System
36

• The answer to that question was
• C. Muscle
• Muscle is made up of cells that are
• similar to each other
• because the stomach is an organ
• an osteocyte is a bone cell
• the digestive system is a whole system.

37
13 Student Question
A herd of animals in the same area is an example
of,

• Population
• Biosphere
• Organism
• Ecosystem

38

• The answer is A. population
• because, a population is a group of organisms of
  one type staying in the same area.
