APES 1.1-1.3 Intro to Ecosystems/Terrestrial/Aquatic Biomes

Front

What is a keystone species?

Back

A keystone species is a species that has a disproportionately large effect on its environment relative to its abundance. Its removal can lead to significant changes in the ecosystem.

Front

What happens to vegetation when a keystone species is removed?

Back

The removal of a keystone species, such as a mountain lion, can lead to a decrease in vegetation due to an increase in herbivore populations.

Front

Which biome has the most nutrient-rich soil?

Back

Temperate Grassland is known for having the most nutrient-rich soil, making it ideal for agriculture.

Front

Define a population in ecological terms.

Back

A population is defined as a group of individuals of the same species living in a specific area.

Front

What is predation?

Back

Predation is a biological interaction where one organism (the predator) eats another organism (the prey), usually of a different species.

Front

What is commensalism?

Back

Commensalism is a symbiotic relationship where one species benefits while the other is neither helped nor harmed.

Front

What is mutualism?

Back

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

Front

What is competition in ecology?

Back

Competition occurs when two or more species or individuals vie for the same resources, such as food, space, or light.

Front

What is the difference between biomes and ecosystems?

Back

Biomes are large regions characterized by specific climate and vegetation types, while ecosystems are communities of living organisms interacting with their physical environment.

Front

What role do decomposers play in an ecosystem?

Back

Decomposers break down dead organic matter, recycling nutrients back into the soil and supporting plant growth.
