Unit 2: Ecology

Front

What is competition in ecology?

Back

Competition is an interaction between organisms or species in which both are harmed as they compete for limited resources such as food, water, or territory.

Front

What happens to carbon in a forest after a fire?

Back

The carbon from the forest will go into the atmosphere as carbon dioxide due to combustion.

Front

What occurs when a population exceeds its carrying capacity?

Back

Density Dependent limiting factors start to occur, resulting in the population decreasing back below carrying capacity.

Front

What is an abiotic factor?

Back

An abiotic factor is a non-living component of an ecosystem, such as air, water, and minerals.

Front

What is a parasitic relationship?

Back

A parasitic relationship is a type of symbiosis where one organism benefits at the expense of another, such as ticks feeding on a dog.

Front

Define symbiosis.

Back

Symbiosis is a close and long-term interaction between two different species, which can be mutualistic, commensalistic, or parasitic.

Front

What is carrying capacity?

Back

Carrying capacity is the maximum number of individuals of a particular species that an environment can support sustainably.

Front

What are density dependent factors?

Back

Density dependent factors are limiting factors whose effects on the population vary with population density, such as competition, predation, and disease.

Front

What is an example of a biotic factor?

Back

An example of a biotic factor is any living component of an ecosystem, such as plants, animals, and microorganisms.

Front

What is predation?

Back

Predation is an interaction where one organism (the predator) kills and eats another organism (the prey).
