What are the two main types of ecological succession?

Back

The two main types of ecological succession are primary succession and secondary succession.

What is primary succession?

Back

Primary succession occurs in lifeless areas where soil has not yet formed, such as after a volcanic eruption or glacial retreat.

Front

What is secondary succession?

Back

Secondary succession occurs in areas where a disturbance has destroyed an existing community but left the soil intact, such as after a forest fire.

What are the four main types of symbiotic relationships?

Back

The four main types of symbiotic relationships are mutualism, commensalism, parasitism, and predation.

Front

What is mutualism?

Back

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

Front

What is commensalism?

Back

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

Front

What is parasitism?

Back

Parasitism is a type of symbiotic relationship where one species benefits at the expense of the other.

Front

What is predation?

Back

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