Organism Relationships in an Ecosystem:
Relationship between organisms comes in 3 major varieties: predation, competition, and symbiosis. These organism relationships can happen between the same species OR different species.
Predation, competition, and symbiosis
In predation, one organism eats another. For example, a deer eats grass. Another example would be a wolf eating the deer. In competition, one organism competes with another organism for resources.
In competition, one organism competes with another organism for the same resources. For example, a squirrel competing with a bird for the same tree counts as competition. Or, a squirrel competing with another fellow squirrel also counts as competition.
In symbiosis, one organism lives with another organism closely together. This can be a friendly or not-so-friendly relationship.
Next Generation Science Standards:
MS-LS2-1 Analyze and interpret data to provide evidence for the effects of resource availability on organisms and populations of organisms in an ecosystem.
MS-LS2-3 Develop a model to describe the cycling of matter and flow of energy among living and nonliving parts of an ecosystem.
What Science Does this Comic Teach?
⇒Topic: Relationship between Organisms
Anything that helps an organism survive counts as a resource. Examples of resources are: food, water, living spaces, mating partners…etc.
