2. the structure and levels of biological organization
A Slide show about
the structure and levels
of biological organization
in a Living Organism

3. By Mr. D

4. Levels of Organization
Grade 5 Science
Levels of Organization
Identifying cells, tissues, organs, organ systems, organisms, populations, communities, and ecosystems as levels of organization in the biosphere.

5. The following slides explain the levels of organization from Cells to Biospheres

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

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

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

9. Organ Systems
Some types of organ systems are, Circulatory, Respiratory, Digestive, Nervous, and Reproductive.

10. Organism
A single living organism. Example: Humans, Cows, Birds, Trees.

11. 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.

12. 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

13. 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.

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

15. Questions Test your Knowledge

16. 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

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

18. A. Organism B. ecosystem C. population D. community
Study the picture below Which level of organization is BEST represented by the entire picture?
A. Organism
B. ecosystem
C. population
D. community

19. B ecosystem
An ecosystem is a community and its nonliving surroundings as labeled here
Air
Bird
Trees
Bushes
Grass
Water
Alligator
Fish

20. 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

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

22. 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?

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

24. 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

25. B. Ecosystem, Community, Population, Organism
Ecosystem, Community, Population, Organism is the levels of organization in descending order

26. 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

27. 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

28. Birds observed during one year
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
Birds observed during one year
Bird
Number observed
Osprey 63
Egret 85
Crane 22
Student
Organisms
Population(s)
Communities 1 3 2
170 4
A Student 1
B Student 2
C student 3
D student 4

29. C student 3
Since an organism is a single living thing you have to include all of them so =170 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

30. 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

31. 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.

32. 10
Study the picture
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

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

34. 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

35. 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.

36. A: Bone Cell B: Stomach C: Muscle D Digestive System 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

37. 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.

38. 13 : Student Question
A herd of animals in the same area is an example of,
Population
Biosphere
Organism
Ecosystem

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