Ecosystem: Biodiversity, Relationship, Succession

Front

What are pioneer species?

Back

The first organisms that appear in an ecological community during the process of ecological succession.

Front

What is ecological succession?

Back

The process by which ecosystems change and develop over time, involving a series of stages from pioneer species to a mature community.

Front

What is biodiversity?

Back

The variety of life in a particular habitat or ecosystem, including the number of different species.

Front

How does high biodiversity affect food webs?

Back

High biodiversity makes food webs more complex and better able to support various species, even if some populations decrease.

Front

What is a herbivore?

Back

An animal that only eats plants.

Front

What is a carnivore?

Back

An animal that primarily eats other animals.

Front

What is a food chain?

Back
