Biotic Environmental Factors Flashcards

Flashcards covering biotic factors, species interactions including competition and symbiosis, and relevant cognitive verbs.

What four examples of limited resources are identified as causes for competition in an ecosystem?

Shelter, Food sources, Water, and Mates

What is the definition of Intraspecific Competition?

Competition between members of the same species.

What concept does Intraspecific Competition drive within a species?

It drives ‘Survival of the fittest,’ meaning only the fittest individuals survive to pass their genes on.

What is Interspecific Competition?

Members of different species competing for resources.

How is Predation defined in the notes?

When one organism kills another for food.

What is the general definition of Symbiosis?

A relationship between two members of different species.

In the study of symbiosis, what are the effects on Species A and Species B in Mutualism?

$+$ and $+$ (both species benefit).

What are the effects on Species A and Species B in Cooperation?

$+$ and $+$ (both species benefit).

How are Species A and Species B affected in a Commensalism relationship?

$+$ and $0$ (one species benefits, the other is unaffected).

What is the impact on Species A and Species B in Amensalism?

$0$ and $-$ (one species is unaffected, the other is harmed).

What is the interaction outcome for Species A and Species B in Parasitism?

$+$ and $-$ (one species benefits, the other is harmed).

What occurs during Mimicry?

One species mimics a different species.

Which species interactions are used as syllabus objectives to compare ecosystems across spatial and temporal scales?

Predation, competition, symbiosis, and disease.
