Species Interactions and Community Structure Assessment

Front

What are species interactions?

Back

Species interactions refer to the various ways in which different species in a community interact with each other, including predation, competition, mutualism, commensalism, and parasitism.

Define community in ecological terms.

Back

A community is a group of populations of different species that live in the same area and interact with each other.

Front

What is ecological succession?

Back

Ecological succession is the process by which ecosystems change and develop over time, involving a series of species replacements and community changes.

Front

What is primary succession?

Back

Primary succession is the development of a biological community in an area where no soil exists, such as on bare rock after a volcanic eruption.

Front

What is secondary succession?

Back

Secondary succession is the process of community change that occurs on previously occupied land after a disturbance, where soil and some organisms still exist.

Front

What role do lichens play in primary succession?

Back

Lichens contribute to primary succession by secreting organic acids that break down rock, helping to form soil.

Front

What is the difference between biotic and abiotic factors?

Back

Biotic factors are the living components of an ecosystem (e.g., plants, animals), while abiotic factors are the non-living physical and chemical components (e.g., soil, water, climate).

Front

What is a climax community?

Back

A climax community is a stable and mature ecological community that has reached a steady state of development and is characterized by a diverse array of species.

How do arctic foxes affect seabird populations in the Aleutian Islands?

Back

The introduction of arctic foxes led to changes in the ecosystem, including a decline in seabird populations due to predation.

Front

What is mutualism?

Back

Mutualism is a type of species interaction where both species benefit from the relationship, such as bees pollinating flowers.
