7.EC.5A.1
Develop and use models to describe the characteristics of the levels of organization within
ecosystems (including species, populations, communities, ecosystems, and biomes).
1. What are the 5 levels of organization in the environment from simplest to the most complex?
2. How is each level defined?
Species:
3. What is a species?
4. True or False. Organisms of the same species can reproduce to make more of that species.
5. Give an example of a species.
Populations
6. What is a population?
7. True or False. Members of a population compete for food, water, space, and mates.
8. Give an example of a population.
Communities
9. What are communities?
10. True or False. Communities involve many types of interactions among the populations.
11. What are some interactions among populations?
12. Example –all of the living organisms (biotic factors) in the environment with the white tail deer,
including ______________________, grass, ______________________, moss,
______________________, and Carolina wrens.
Ecosystems
13. What is an ecosystem?

14. True or False. Example –all of the living organisms (biotic factors) in the environment with the
white tail deer, including pine trees, grass, squirrels, moss, mushrooms, and Carolina wrens as well as
all of the abiotic (non-living) factors such as rivers, soil, air, and rocks
Biomes
15. Individual ecosystems grouped together according to the climate, the predominant vegetation,
and characterized by adaptations of organisms to that particular environment are called
______________________.
16. Give an example of a biome.
17. What is a habitat?
18 The particular role of an organism in its environment including type of food it eats, how it
obtains its food and how it interacts with other organisms is called its

7.EC.5A.1
Develop and use models to describe the characteristics of the levels of organization within
ecosystems (including species, populations, communities, ecosystems, and biomes).
1. What are the 5 levels of organization in the environment from simplest to the most complex?
Species, Populations, Communities, Ecosystems, and Biomes
2. How is each level defined? By the type and number of biotic (organisms) and/or the abiotic
(non-living) factors present
Species:
3. What is a species? The individual living organism
4. True or False. Organisms of the same species can reproduce to make more of that species.
5. Give an example of a species. Example –white tail deer
Populations
6. What is a population? All of the individuals of a given species in a specific area or region at
a certain time.
7. True or False. Members of a population compete for food, water, space, and mates.
8. Give an example of a population. Example –all of the white tail deer in South Carolina
Communities
9. What are communities? All the different populations in a specific area or region at a certain
time.
10. True or False. Communities involve many types of interactions among the populations.
11. What are some interactions among populations? obtaining and use of food, space, or other
environmental resources.
12. Example –all of the living organisms (biotic factors) in the environment with the white tail deer,
including pine trees, grass, squirrels, moss, mushrooms, and Carolina wrens.
Ecosystems
13. What is an ecosystem? One or more communities in an area and the abiotic factors,
including water, sunlight, oxygen, temperature, and soil is an ecosystem.
14. True or False. Example –all of the living organisms (biotic factors) in the environment with the
white tail deer, including pine trees, grass, squirrels, moss, mushrooms, and Carolina wrens as well as
all of the abiotic (non-living) factors such as rivers, soil, air, and rocks
Biomes
15. Individual ecosystems grouped together according to the climate, the predominant vegetation,
and characterized by adaptations of organisms to that particular environment are called Biomes.
16. Give an example of a biome. Example –the temperate deciduous forest that the white tail
deer lives in.
17. What is a habitat? The place where an organism lives in order to obtain its food, water,
shelter and other things needed for survival is called its habitat.

18 The particular role of an organism in its environment including type of food it eats, how it
obtains its food and how it interacts with other organisms is called its niche. For example, the niche
of a bee is to pollinate flowers as it gathers nectar for its food.
