Ecology - Section IV Review (interactions, niche, competition)

Front

What is competition in ecology?

Back

Competition in ecology refers to the interaction between organisms or species in which both are harmed as they vie for limited resources such as food, space, or mates.

Front

What is an ecosystem?

Back

An ecosystem is the collection of all biotic (living) and abiotic (non-living) factors in a specific area, interacting as a system.

Front

What is intraspecies competition?

Back

Intraspecies competition is competition between individuals of the same species, often for resources like mates, territory, or food.

Front

What is interspecific competition?

Back

Interspecific competition is competition between individuals of different species for the same resources.

Front

What can cause intraspecies competition among animals?

Back

Intraspecies competition can occur due to a limited supply of resources, such as food, water, or space.

Front

What is a niche in ecology?

Back

A niche is the role or function of an organism or species within an ecosystem, including its habitat, resource use, and interactions with other organisms.

Front

What is mutualism?

Back

Mutualism is a type of symbiotic relationship where both species benefit from the interaction.

Front

What is parasitism?

Back

Parasitism is a relationship where one organism benefits at the expense of another, often harming the host.

Front

What is the difference between biotic and abiotic factors?

Back

Biotic factors are living components of an ecosystem (like plants and animals), while abiotic factors are non-living components (like water, soil, and climate).

Front

What is the competitive exclusion principle?

Back

The competitive exclusion principle states that two species competing for the same resources cannot coexist at constant population values; one will outcompete the other.
