Biotic and Abiotic
Living or once-living part of an ecosystem
• Can be producers, consumers, or decomposers
• Examples: grass, birds, lions, fungi
Biotic Factors
An interaction in which one organism hunts and eats another organism (prey)
Predatory Relationship
Any living thing
• Only able to breed with organisms of the same species
• Can be plants, animals, bacteria, protists, fungi, etc.
• Smallest level of organization
Organism
All living things are made of cells
Theory #1
an organism whose cells lack a nucleus and other organelles
• bacteria such as Staphylococcus Aureus and Escherichia coli
Prokaryote
• Non-living part of an ecosystem
• Come in different types and vary among ecosystems
• Organisms and populations often compete for abiotic factors such as availability of light and water,
range of temperatures, or soil composition
• Examples: sunlight, temperature, altitude, rain
Abiotic Factors
A relationship between organisms that require the same resources in the same place.
Competative Relationship
A group of organisms of a given species in a particular area
• Same population of organisms = same species
• Can have different genetic makeup for certain traits (i.e. hair color or eye color)
• 2nd level of organization
Population
The most basic unit of structure and function of life is the cell.
Theory #2
an organism whose cells contain a nucleus and other organelles
• humans, plants, and animals
Eukaryote
1 example of organisms or populations
competing for biotic factors.
Answers will Vary
a relationship in which both individuals benefit from the activity of the other
Mutalism
All of the populations in a specific area at a given time
• Includes populations of organisms from different species (all living things)
• 3rd level of organization
Community
All cells are produced from existing cells
Theory #3
an organism that is made up of only one cell
• amoeba, paramecium, and euglena
Unicellular Organisms
1 example of organisms or populations
competing for Abiotic factors.
Answers will Vary
a relationship in which one organism causes harm to another by living in or on it
Parasitism
All of the living and nonliving factors in an area interacting together
• Biotic and abiotic factors
• Can include a large or small area
• Largest level of organization
Ecosystem
Red blood cells, white blood cells, muscle cells, nerve cells, and skin cells
Cells in the Human Body
an organism that is made up of many cells
• trees, ants, and mushrooms
Multicellular Organisms
List A: Cow, Chicken, Wolf, Rose, Apple Tree
List B: Sunlight, Temperature, Soil, Water
List A: Biotic Factors
List B: Abiotic Factors
a relationship in which one individual benefits and the other is unaffected
Commensalism
All of the populations of living things in an area
Community
Parenchyma, collenchyma, sclerenchyma, xylem, phloem, meristematic, and epidermal cells
Cells in a plant
List A: Grass, Flowers and Algae
List B: Grasshoppers, Snakes, and Bears
List A: Autotrophs
List B: Heterotroph
